Taking off your Radio Controlled Jet

Okay I take it on me, my bad, I have been writing about all the things but the simple basic maneuver which is taking off your rc jet. Yes ofcourse take off is the first move anyone in the hobby of radio controlled flying hobby would do. Although it is the most basic and easy maneuver but still some of you will face some difficulty in taking off your rc airplane specially smooth take offs because one will require some practice in overcoming irregular take offs and becoming a consistent rc jet take offer. So no worries because this post is all about smooth, sleek under controlled take off doesn’t matter which model you are flying. See this step by step guide:

- As we know the basics of any take off that they are performed into the wind. You need to have a windsock to know the direction of wind. Although all major air fields have but you can take a hint from your hanky. Intensity of the wind is to be judged as well, too much of a wind can make the moves erroneous. You need to position your rc jet into the wind and also mark any land mark not of much height because you are going to make a turn above it after climbing a height.

- Positioning your remote controlled airplane is very important. Make sure that it is placed in the middle of the runway because sometimes rc airplanes go cut sides and go off the runway. Your rc aircraft is facing the wind and positioned between the runway.

- Some of the air fields have marked pilot positions, these are the spots from where you fly your rc airplane if you are using an airfield, get there, choose a nearby your rc plane.

- Better take offs are always about swift speed catching. You need to give smooth but full throttle in a short time so that air cuts the controls surfaces faster and give you edge in lifting your rc jet in the air.

- You will be required to use a little rudder here and there to keep your remote controlled aircraft in the middle of the runway and in a straight line so it can catch up speed faster. Use a small up elevator if you are flying a tail dragger, this will keep your rc plane to nose down.

- After seeing your rc jet gaining full speed, you need to pull back smoothly and gently, if you make it climb too steep, your rc airplane can catch a stall which can happen due to low altitude. Keeping it in a gradual climb and straight for a little while will give it stability. You may want to apply correction to bank by tapping the rudder or aileron stick. You will have to plan your height from where you want to take a turn over the land mark chosen earlier.

- After reaching the land mark location for the turn, reduce the throttle to half and level off. Take the turn in the direction you want by banking your rc jet or aircraft while maintaining the altitude so you don’t find your remote controlled plane ditching on the ground.

That’s it; you have made a very smooth take off. You deserve a pat, enjoy flying.

RC Jet Planes – Rolling Loop Aerobatic

In the last post we covered up all the previous knowledge we had shared through this blog of rc jets. I can ascertain that many of the readers of this blog by now may have been doing great maneuvers with their rc airplanes and some might have reached and finished their skills to the level of flying rc jets. There will be some of you who might have become experts in doing some awesome maneuvers but there are some who need to learn them and that is why I thought to write some posts for how to do some advanced maneuvers with your rc jet. For today we all take a look into some very known aerobatic move made by all rc jet lovers, those fighter jet planes out there which carry real human pilots use the same technique to perform this move, you must have seen them doing this move in real at some air show or in television. Let me tell you something which I have never shared and that is if it was not for this cool move of real fighter jet plane I saw in an air show back then when I was 8 year old, I might not have been in the hobby of rc jet planes. The great move of rolling loop was made by the pilot so immaculately while passing by the main center of the ground that it got its deep impression on my brain. Okay enough of rambling, now let’s take a look at how the rolling loop aerobatic move can be achieved with your rc jet:

The rolling loop is very cool when you see it performed by any rc jet. To perform this cool move you must know how to do it precisely so you may not lose your rc jet. To be safe and as a rule of thumb, you should take your rc jet at a high altitude before trying to learn any new maneuver on your rc jet. This rolling loop move can be done on your park flyer, your electric rc jet, scale rc jet and model rc jet. Taking your rc jet to a sufficient height/ altitude ensures that recovering time from any mistake made is in your hands. You should try this move in the direction in which feel most comfortable, after doing it for few times. Follow this step by step guide to perform the move:

- Make your rc jet plane into the wind and remember that your scale rc jet is on high altitude.

- Rolling loop is achieving a vertical circle while rolling your rc jet simultaneously.

- For making a round vertical loop with your plane of reference, while making a 360 roll, give full throttle and begin climbing the altitude more.

- You would want to use a little rudder to up hold rc jet in a vertical position while climbing the altitude.

- Up elevation and aileron is to be used to make rc jet roll while climbing.

- You want to watch the climb with respect to the roll rate carefully as wings need to be at horizontal level when rc jet is at the top of the vertical loop.

- When your rc model plane is at the top you should decrease the rudder input, this is to make your plane descend from the top of the loop.

- At this point you should decrease the throttle but continue to use aileron with rudder input to make rc jet maintain its rolling with a constant rate.

- From the top of the loop where you started descending your rc jet till the cardinal point (from where you initiated the vertical climb) your plane should complete one more 360 roll and achieve its horizontal reference level upon reaching the cardinal point.

- In other words your rc jet makes 2 rolls of 360, each on half of its way completing the vertical 360 loop.

Was that difficult? I don’t think so (well only in reading :) ) when you will practically go doing it will take a little time in mastering it. This rolling loop move is more difficult to perform on rc jet planes as they are faster than rc airplanes and other rc model airplanes. Doing it on scale models look cooler as they give the feel of making a real jet rolling in a loop. Try roll looping your rc jet plane in an open ground so you can perform it with ease with the stress of getting into electric wires, buildings and towers.

RC Jet Airplanes - Explained

RC Jet Airplanes:

I hope that all the information that we are sharing here on this blog are giving a good value to all of the readers who are in the hobby or intend to fly rc jets. Well, when I started this blog around two months ago, I wasn’t expecting to have this kind of a traffic in this short span of time, but yes this blog about rc jet airplane flying is doing good and hopefully continue to do better in coming days. In this post I just want to have a refresher of all the things which we have discussed regarding rc jets flying earlier and have good value in getting them read again specially for the new readers of this blog.

To begin with I want to establish something first with all who are new to this blog and are intended to get the feel of flying rc jets soon. The thing to establish here is that we all who are attached to this hobby of rc jet flying are in this hobby because we have love for flying and not only flying but flying fast, speedy in the fastest flying machines which rc plane hobby has to offer and those are definitely rc jets , not the rc helicopters. No offence to rc helicopter lovers out there as I like rc helicopters for doing maneuvers which rc jets cannot do but they lack the element of speed which has all the thrill attached. With flying radio controlled jets you can achieve speed in access to 200 miles per hour, now that I call a real fun with this kind of speed only can give and else not.

For all the new comers in radio controlled hobby, I want to tell them that with advancement in technology now we have radio controlled planes which fly with the power of radio controlled electric motors. Okay that is an advancement and a very good one but what we have established in the opening of this post about the speed and faster flying; the radio controlled jets with the propelling power of electric rc motors, lack that speed element so we can call them electric rc jet, not the real rc jets with turbo rc jet engines. The rc jet airplanes which use real gas engines, are the ones which go higher on speed and in proportion to thrill. There are types of rc jet engines, which we although have already taken a very detailed insight in earlier post dedicated to them, but we will again go through it, for our new readers.
Radio control rc jets which use gas engines are faster and are near to the real jet. The types of rc jet engines which these planes use, make them called with names which are associated to the engine type, and these are:

Rc jet airplane-Pulse:

This type is very simple in design, it only has one moving part which is its opening and closing valve. Rest of the engine only consists of a tube with a fuel igniter. These types are very noisy and are inefficient hence not used much. Especially the sound is so irritating that this can only be flown away from population unlike the park flyers which are less in sound and use electric rc motors for propulsion.

RC Jet Airplane – Turbo

This one is which I called the real one as it uses a turbine engine which is as same as the ones used in the actual jet. The little difference is of the stages of compression used. Axial flow is used in the real jet and the centrifugal flow is used in the rc jet turbine. This rc jet has all the speed we require, with the top speed reaching more than 250 miles per hour. This is also not a park flyer. These are big radio controlled airplanes, require fueling with kerosene or Jet A-1 fuel, same as used in the real ones. Also the maintenance of these rc jet airplanes is of the greater concern for few who just like to fly but don’t want to get their hands dirty. We will see this aspect a little later.

RC Jet Airplane – Turbo Fan:

This type is almost the same as the turbo one but with a slight twist in the burning cycle. To make this type more efficient on fuel, some quantity of cool air is mixed with the heated air fuel mixture to increase the fuel efficiency but reducing the exhaust speed.

Okay, we have seen what are the types of rc jet airplanes out there which use gas engines. Let’s now see what is electric powered radio controlled plane has to offer since not being great on speed. The ones which use electric motor as a propulsion means are also great flyers, they are able to do some very advanced kind of moves. They are very efficient on pocket as they come cheap as compared to the gas types. The electric motors are now made very efficient by the use of brushless technology. Yes the brush less motors use have made the electric loses of these rc jets very less, hence increasing the flying time. These types of rc jets now have kind of batteries like lithium polymer, which are able to give very long duration of flights having bigger Amp hour charge holding values. When you use these kinds of rc jets you do not have to worry about fueling them and maintain them every now and then, even you don’t have to clean them more often as compared to the ones which use gas engines. Electric rc jet airplanes are very good park flyers as they are very low in noise and can be flown in your neighborhood so you don’t have to go far in the air field and grounds from your home. These are also called park flyers as they can be flown in a park nearby you and amaze children out there, if you have to .. hehe

The radio control jets which use gas engines on the other hand are not the park flyers if you are looking for one, these are real speedy rc jet airplanes, which make sound and look same as of a real jet. These rc jets are for you if you are not afraid of getting their hand dirty as when you keep this kind of rc jet airplane, you will have to take a good care of it in maintenance, fueling and cleaning of exhausts and engine oil. Although these rc jet airplanes are heavy on pocket and are not suitable for ones who are just starting the flying hobby, but these are the real ones on which you will have to shift eventually after having some learning done on the propeller type electric airplanes and electric rc jet airplanes.
I now call it a post for rc jet airplanes as this has really gotten long. Those of you who are enjoying the good times of flying rc jet airplanes may want to contribute their experiences by commenting here. Till next time..

Happy flying!!

Types of RC Jet Engine

The most impressive technology that the Remote control industry has yet created is RC Jet engines. The look and the sound of Remote Controlled Jets enable them to be an amazing sight at the flying field. In this post we will look at the differences between a real full scale jet engine and an rc jet engine. Remember that we are not talking about electric rc airplanes or electric ducted fan models electric rc jets those are found in hobby stores out there but we are only taking into account the real jet engines which are scaled to be used in radio controlled or rc jets and burn kerosene or jet A-1. Many a times EDF jets (electric ducted fan jets) are confused with real gas rc jets, though EDFs are great models and can perform advanced aerobatics.

You must know that rc jets having gas turbo engines are the most complicated and expensive radio controlled airplanes available before you go buy one. A beginner should clean their hands on the slower kind of beginner rc airplanes before getting an rc jet as to fly one you will require a huge budget and many hours of flying experience to be a successful rc jet flyer.

How radio controlled Jet Engines Work:

In order to have an understanding of radio controlled jet engines, we are required to have an insight look at the real full scale jet engine used by passenger carrying jets. The definition of a jet engine is that it is a device which operates in a medium of fluid which is air, and discharges it at a higher rate, to achieve propulsion. This is simple Newton’s third law of motion which is “every action has an equal and opposite reaction”. In other words radio controlled jet engine expels air at a higher rate than it sucked in, hence getting propulsion. This is the basic principle on which all jets and radio controlled jet engines work.

Now take a little deeper look; since we know that volume and temperature are directly proportional to each other, the heated air will have more volume as it expands. That is why when the temperature of a given volume of air in a chamber increases, its pressure increases as well. When we release this heated, pressurized air, it exits at a greater speed then the speed it entered the chamber, as a result the engine gets the thrust to move forward.

Now let’s discuss the types:

Pulse Type:

This one is a simple kind of a radio controlled gas engine, consists of a tube, a fuel and igniter. The tube has a shape which makes the inner flow of air more in velocity and less in pressure. An radio controlled or rc pulse jet engine works by igniting air and fuel mixture at a very high frequency of air bursting in from the inlet. The air coming in from the inlet has more velocity and less pressure but when inlet closes and fuel gets ignited in this air, the air gets hot to escape from the outlet which is a converging opening. This makes the escaping air high velocity. The escaping air from the chamber leaves a low pressure, which upon opening up of the inlet makes the air to rush in. This whole cycle continues to keep the rc pulse jet running.

This process is described in the diagram below:

Though radio controlled pulse jet are very simple in design but are very loud and not very efficient. Mostly hobbyists use them because they are simpler in design and do not have moving parts. They are built in small scale to be used. They are not much used in full scale jet airplanes.

Turbo RC jet:

In this type of radio controlled jet engine, turbines are used to compress the air, adding fuel and then igniting it to get the thrust. A turbine is actually a compressor which consists of a set of many blades which when spin, move the air through each other and towards the closed end, this builds up the pressure and compress the air.

This figure shows the working cycle of a Turbo RC Jet Engine:

A typical cycle of a turbo is:

1. Air is compressed when it enters the turbo chamber.
2. This compressed air is then enters the combustion chamber where it is mixed with fuel.
3. Upon ignition, the compressed hot air leaves the chamber at a high speed, giving the turbo rc jet engine propulsion required.
4. Interestingly, the hot air leaving the chamber is routed through a turbine which drives the compressor which was used to compress the air in the first place.

Turbo rc jet engines are very efficient as it is evident from its working cycle where the energy produced is also initiating the process. Though these are very efficient but are not in subsonic speeds, turbo radio controlled jet engines require higher operating speed than sound to give their optimum performance. That is why turbo engines are not used in the subsonic operations.

Turbo Fan RC Jet Engines:

As we discussed the working process of a turbo radio controlled jet engine, turbo fan also works on almost the same principle. The cycle gets a bit different where not all the air intake is taken through the combustion chamber but some of the air is made to exit not burned. Some cool air is mixed with the air fuel mixture to increase the fuel efficiency, reducing the speed of exhaust.

This figure illustrates working cycle.

How Model RC Jet Engine Works:

Until recent years, Model radio controlled jets were not true Turbojet engines as previously, the look of the rc jet airplane was spoiled by electric motors or gas engines with a propeller, Pulse engines or Ducted fan airplane types. Now we have real turbo rc jet turbine engines for our beloved radio controlled airplane flying hobby.

The little difference rather an advantage for our radio controlled jet engine is the type of turbine. The small rc jet engine uses the centrifugal flow turbine as compared to the axial flow turbine used in bigger passenger jet planes. The difference between the two types of turbojet turbine is the stages of compression. In a centrifugal flow rc turbojet turbine, the air when passes through the rotating impeller it is thrown outwards after entering into the turbojet turbine. The air is compressed when it hits the inner walls of the turbojet turbine chamber after that the air is passed to the turbojet combustion chamber. This greatly compressed air has an increased temperature and in turn pressure which upon ignition gives immense energy.

The Combustion Process:

As like real jets, the fuel which is used in all types of rc jet engines is Jet-A1 commonly known as kerosene. To mix this fuel with the hot pressurized air, the fuel is entered in the turbojet combustion chamber in form of a fine mist. A small glow plug just as used in the 2 or 4 stroke engines is there in the combustion chamber to ignite the mixture of hot air and fuel. The fuel air mixture, upon ignition explodes within the turbo radio chamber. The shape of the chamber is such that it compels the hot gases rearward the turbine and in turn increases the velocity of hot air through the turbine. This all makes the pressure of the hot gasses to build up at the narrowing cone pipe to exhaust with a great thrust from there.

This figure below shows the basic working of a centrifugal rc jet engine:

Electric RC Jets - Your First Option

We are moving steadily towards our goal of flying an gas rc jet which is not far off as today we are going to have our hands on a regular kind of a remote controlled airplane which will be an electric remote controlled jet. In last post we discussed the start off period for deciding how you should go for selecting your type from RTF (ready to fly), ARTF (almost ready to fly) and the kit (where you actually start to fabricate from scratch). I hope that you must have decided your type of remote controlled airplane and if at all you like to do things with your hands and decided to go for a Kit, by now your first rc plane must have taken some shape and it is very much possible that your rc airplane is now ready to fly and you have tested it. Today we will discuss the two types of power sources available for flying our rc jets. One is electric powered remote controlled jet and the other is called gas remote controlled jet both as their name suggest have different power sources electric powered have electric motor fitted in it and gas one has a gas engine. I will keep my focus to electric remote controlled jets more and in the next post my focus will be gas powered remote controlled jets. But before discussing directly the electric rc jets and the gas ones, I am feeling somewhat a historian today and want to discuss the early hobby models of airplane power sources. Don’t worry, I won’t barrage about it and try to keep it short… here it comes…

Since the flight of the first practical rc airplane, progress with performance depended on technology as like any other field. All remote controlled airplanes require to be constructed of strong but light materials, like their big brothers, the passenger carrying airplanes, and require some kind of power to achieve their quest of flying in the air.

Early form of light weight and very inexpensive power source for model airplanes was twisted rubber bands, now don’t laugh as we could have been the ones living in that era too (lucky us, we are not :) ). As the rc airplane models progress and grew in size, weight and require more power, enabled small gas rc engines to become the preferred means of powering them. Having gas rc airplanes very powerful, these also require a heavy airframe to handle the engine’s vibration. The advantages of gas rc jets and the disadvantages will be discussed in my next post as for this one I just want to focus on an electrical powered airplanes more. Sure we will have to discuss the cons of gas ones to come up with the pros of electrical remote controlled jets.

As I said the gas ones require a heavy and strong airframe to handle the vibrations of the engine, it also requires proper maintenance, cleaning of messy oil leakages and the fuel smell requires handling too. In addition they produce a lot of sound which may be a problem for some of you living in a close neighborhood, though gas one is always required to be flown in a ground or an airfield away from the population. And the main problem which the beginners face is that the gas rc airplane do not come cheap, yes they are costly, one drop on the ground and you will be seeing yourself repairing your gas rc jet, where as electric remote controlled planes are more robust, few drops from quite a height does not shatter them easily. The benefit of electric power is it being cheap, makes them the beginner’s first choice. But there are many other benefits attached with electric remote controlled jet besides being cheap and here they are:

The Advantages of Electric Powered Jets:

We have already discussed that electric driven remote controlled jets are reliable, don’t break easily, their convenience of operation, low maintenance, low vibration, low noise and light on the pocket. However some of you engineer brains might be thinking that where is the aspect of speed in them, which is our main concern since we are only striving to reach our goal of flying a real rc jet, with real turbojet engine and further an rc rocket, if possible. You have very right concerns over speed of electric remote control jets, because we have examples of electric cars that they don’t speed that much so how can an remote controlled jet powered by electric? Well gone are the days of bulky electric batteries which used to hold little amp hour of current, now we have Lithium batteries which are lighter and hold a longer charge for your electric powered planes. The other concern you might have is the power of the electric rc jet motor, as we all know that an remote controlled electric motors cannot beat the gas remote controlled jet engine when it comes to power. Well, cutting the weight in electric rc jet and replacing the brushed motors with brush less motors have enabled electric rc jet to be lighter weight thus enhancing its speed. Let’s see what a brushed and brush less motor has to play in electric rc jets.

In the common brushed motors, sliding contacts are used to provide current to the conductor in the magnetic field so that the conductor can rotate. These sliding contacts most of the times are carbon brushes which are in contact with the conductor of the electric rc jet motor all the time, this contact makes the brushes and conductor to produce heat and wear tear. This causes current losses in the electric rc jet which makes it lose power. With the introduction of brushless motors this loss of power has been taken care of in electric rc jets. The switching of current to the conductor happens electronically in brushless motors by using electronic switches in electric rc jet motors.

Now let’s take a look at the other factor of power saver in electric rc jets which is the battery. Three main kinds of batteries are used in electric rc jets, Lithium Polymer (LiPo), Nicel Cadmium (NiCad) and Nickel Metal Hydride (NiMH). Though three of them are lighter and hold long charge for electric rc jets, LiPo batteries are lighter and hold more charge than the rest of the two.

Electric rc jets come in different shapes and sizes like powered sailplanes, aerobatic models, scale models and ducted fan type. Let’s discuss the types of electric rc jets with respect to the option given to maneuver an electric rc jet, which with respect to radio controls called channels, yes right more channels more options you have to maneuver your electric rc jet.

First we have simple 2 channel electric rc jet, simple and easy, only yaw and pitch controls are available with 2 channel electric rc jet. This one is great for very initial electric rc flights as 2channel electric rc jet comes really cheap. Then we have 3 channel electric rc jet, which gives you controls over yaw, pitch and altitude of your remote controlled jet. The 3 channel is good for occasional flyer who wants a better control over their plane and still keep a not very heavy load on the pocket. Well the 4 channels electric rc jet is what a real enthusiast require, this one offers full control over the yaw, pitch, bank and throttle acceleration.

Okay, enough for today, I will go for gas rc jets in the next post. To conclude this one, I would say that if you are new to flying rc airplanes then electric rc jet is for you after trying out the slower electric pusher airplane and also you should clean your hands on 2 or 3 channels electric rc jets and then spend your hard earned money on 4 channel ones.

Happy flying !!!


Gas RC Jets - Pros and Cons

Gas RC Jets:

The post before the last one had me make a promise with all of you that the coming one will be about gas rc jets, so here it is. In the last post we have already discussed about the gas rc jet engines, i.e. turbinejet and other kinds which are used in gas remote controlled jetplanes. In today’s post I will only make my focus to gas remote controlled jets, not gas engines. Like the post earlier than the last one, we put all our focus to electric side and discussed all the positive sides of them, today its gas remote controlled jets turn and unlike the concept which was developed in the electric remote controlled jet post that gas powered jets have all the disadvantages attached and who are the smart guys out there who even try them; this concept about gas powered planes is going to change because these are the ones which are called veteran in the rc jet hobby and nobody can get the crown away from them. There are jet properties which electric remote controlled jets don’t have and those features and properties make gas rc jets a hard core choice for the enthusiast hobbyist. Let’s talk about what they have to offer: first the cons.

Gas RC jets- The disadvantage side:

The new comers to remote controlled airplanes hobby always make gas rc jets look at a disadvantageous side, though it’s not that gas powered planes in general do not have any but it will only be logic if we see them in the right perspective. Gas rc jets have complaints of being noisy, yes they are, but they also give more power than the electric ones. The maintenance of these gas types is also a concern for some flyers, well I don’t think one who doesn’t want to take care of his stuff in whatever field he is has anything good going for him there, individuals like these are better advised to leave the hobby and start flying paper planes . Yes I know gas rc jets give smoke, you have to clean the exhaust, change the engine oil etc etc. One rather disadvantage for beginners is that nitro planes are expensive, they are expensive to buy and expensive to keep… and for a beginner it is a big No. Beginners must get the slower electric ones first and once they are all done with it, then they should try the gas rc jets because once the gas rc jet is broken you as a beginner gets a broken heart and a hole in your pocket. You will require a full scale repair kit and an indepth working knowledge of gas engines in order to maintain them and repair when they get broke. Gas rc jets possess a real threat of fire when they crash because of the fuel they use. Gas rc jets use A-1, which is kerosene and is highly flammable. Despite of all these disadvantages, gas remote controlled powered jets have something to offer which electric ones do not have in them, the advantages are here:

Advantage side of Gas RC Jets:

Are also called nitro remote controlled airplanes, these are very close to the real ones out there. The things which you must take into account are that for a nitro remote controlled airplane you will have to deal it as like owning a real airplane. You will have to fuel it and then refuel it (which requires money), change the engine oil for keeping it clean, tweak it adjust its parts to get the optimum. I hear some of you are saying hell that is a lot of work to do. Well I would say it is good for people who like doing things from their hands; I think all of us who are in this hobby are the ones who like to do things with their hands, it is possible that you don’t know it unless you do it. I actually like building something with my hands and get my hands dirty, but once it is repaired or made, I really enjoy it and I hope it does the same for alike in this hobby.

Gas rc jets have longer duration of flight as compared to the electric powered, nitro rc airplanes once fueled can fly for hours, where electric ones only can last for half hour or so. Though electric powered are now coming with longer battery times and with brushless motors the loss of current is very less and so their flight time has increased but they still can’t beat the duration of gas rc jets.
The factor that gas remote controlled aircrafts are the stamp for a hobbyist that he or she is really into the hobby if they possess one. This authenticity factor is what makes gas rc jet a must have for all of those who want a more realistic experience of flying. Their engine sounds like the full scale passenger carrying jet, they operate and fly like them too. They have much more torque and speed than the electric ones could have ever. Yet another advantage to be used in gas rc jet races and for the thrill which comes out of fast machines. A good finely tuned gas remote controlled jet can go more than 200 miles an hour. Now that really thrills and if you remember what brought us in this hobby? Yes exactly… the speed.

I believe all the advantages which I have described above are enough for those of you who were reluctant to have a try for a gas rc jet but again you must learn the skills on a slower electric airplane and a electric rc jet one before going for a gas rc jet. It is all worth taking the hassle of cleaning and maintaining your gas rc jet when this pretty machine gives you the thrill of speed while flying it.

You just have to take care of few things and sure your gas rc jet will never break on you. Keep the it and its engine as cleaned as possible, dirt is bad for everything moving and gas powered planes have many moving and rotating and spinning parts. Do a little maintenance before and after the flight, the maintenance procedures come with every plane and are easy to follow. Change the engine oil regularly for keeping your remote controlled jets clean from inside, tune the engine for better performance and longer life.

Happy flying!

Small RC Jets

The feeling of flying is something which is linked with flying small rc jets, many folks think in this manner, well they all have some reasons. Remote controlled jets are the machines which are the best in the world of remote controlled airplanes. The thrill which flying wonders give, drives people crazy because of the joy which it brings. You can always ask somebody who has flown an remote controlled airplane the joy it gives. The experience is out of this world. It can be categorized into two categories:

Types of small rc jets:

Pusher type and electric ducted fan type. The remote controlled jets which use gas turbine are bigger in size. Well I have mentioned the two because you need to select the right one in the beginning with respect to the speed, so selecting a pusher is advisable for the ones who have just started the remote controlled planes hobby. When you have gotten an idea of how to fly rc jets on a pusher type then you can shift to the ducted fan type. The ducted fan type are more speedy than the pusher type. Only when you have cleaned your hands on the small rc jet of ducted fan type, you can go for the gas turbine rc jets which are bigger in size and also in speed.
The point in telling you to select the small rc jet for learning is that by doing this you will be good to your pocket. Because buying a bigger gas turbine remote controlled jet with a gas turbine engine is very costly. If at all you have bought it, maintaining it is again not a cheap idea.
The small remote controlled planes of pusher type is handled with much ease by a newbie. The ones available in the market are very quiet and also very handy in flying them in parks, and near by fields where you cannot fly gas rc jets. In fact any place is good for this remote controlled airplane because even being a beginner you are very less susceptible to crash it. You would want to avoid flying your small rc jets in windy and stormy days because you would never want to lose this little wonder.

After the pusher remote controlled jet, you would want to switch to a little faster electric ducted fan type. While you can enjoy flying the rc jet of ducted fan type with a little faster attitude you can never compare it with the gas turbine rc jets. The gas ones are super fast flying machines. By the time you have acquired skills on the small ducted fan remote controlled jets you will be very good in flying gas rc jets. The aspect which cannot be neglected is that there are some of you crazy as me out there who can make a mistake of buying gas rc jet as your first remote controlled plane and then repent, as it can never be handled if you have not flown any slow speed plane. I am saying all this from my experience of flying rc jets of all types. You must remember that you are here to stay in this hobby so it is better to start right and give yourself chance of learning the flying skills with right kind of flying machines and those are definitely small rc jets. Some of you, who always go with the right start, can buy a learner remote controlled plane and after having a taste can shift to any kinds of rc jets.

Happy Flying!!
