Ready to Fly Model AIrcraft

RC RTF planes, or RC Ready to fly planes, are the most common models used by novice RC plane enthusiasts. RC RTF planes come pre-installed and ready to operate, in a box and all you have to do is to put a few outer parts like wings,tail and fan together, to get your RC airplane going. This is one of the main reasons for the popularity of RC RTF planes with starting RC airplane enthusiasts.

The first RTF RC planes were created in 1960s when transmitter technology became cheaper. This made it affordable to build devices with RC technology on a large scale basis, as people could afford it now. The RTF RC models range was very limited at that time and all of them were gas fuel powered. Since then, there has been a tremendous progress in the field of RC RTF planes, with many electric models becoming a huge hit with enthusiasts.

Unlike RC kits or published plans which take hours to complete, it is extremely easy to get an RC RTF plane on the field. RC RTF planes come fully equipped with all the essential parts like the plane, the remote control device, the antennas, the engine etc. It takes only about fifteen minutes to put everything together and you don't have to be an expert in RC models to do this job. The instructions are given with model and you just have to follow them to the dot. RC RTF planes are best for people who don't have the time or patience to put a RC plane together.

RC RTF models are also a great way to introduce the RC model hobby to your child or friend. As these provide a completely hassle free flying experience, you will be able to enjoy the art of flying RC models to the fullest, without the need for extreme technical knowledge. In order to find the most suitable RC RTF plane for yourself, you should first conduct a survey on the best models available, and your budget. If you are buying your first RC RTF model, then you would be pleasantly surprised with the range of planes which are available in the market. From small gliders to big jets, you can find any type of aircraft in RC RTF model. They come in both electricity and gas fuel versions. Some popular manufacturers include Megatech, Hobbico, Vortex and Aspire.

The first time RC RTF flyers should make sure that they buy a RC RTF aircraft which is easy to handle and operate and as they get experience in flying, they can progress to the more complex models. So, what are you waiting for? Go to your local hobby store or just log on to an internet site that sells RC RTF models and get one.

How to operate model aircraft engine?

Setting Up, Operating and Maintaining Model Aircraft Engines
Having a reliable power system in your model airplane is critical to your fun if not the aircraft's health.  The power system should be dependable, consistent and provide years of service with little maintenance or tinkering.
The average sport airplane is designed to have the engine and tank installed as ideally as possible while providing good access to the engine for maintenance.
These pages should help you avoid confusion as to what you need, what you do not need and to dispel some myths.  Hopefully this information will get you on the right track by helping you avoid problems or wasting money.
I e-mailed Clarence Lee, the Engine Clinic columnist for Radio Control Modeler magazine, and asked if he would use some of his valuable time to read over these pages to ensure the information I am providing is correct.  He replied with excellent feedback that I have included in sidebars on the appropriate pages.
The following pages give specific information about engine mounting, propellers, spinners, throttle linkages, fuel tanks, lines, fuel and air filters, hand starting or using an electric starter and general maintenance suggestions.

Jet Engine RC Helicopters

RC Helicopter Direct Drive Turbines

RC Helicopter jet engines spin their axels at far to great a speed to directly hook up to the rotors, so the most obvious way to slow them down is a gear box. In the direct drive design, the turbine shaft is directly connected to a gear box, which slows down it’s rotation speed and powers the main rotors. This is the most obvious and simple design, but it has a few problems that have caused another, more sophisticated one to gain popularity. For example:

1. All the thrust produced by the jet engine is wasted. Because the only work done by the engine comes from it’s main turbine shaft, all the thrust from the engine is left unused. The thrust from the engine is usually channelled outside the RC helicopter.
2. The wasted thrust can lead to unwanted motion. RC jet engines produce a lot of thrust, and forcing it outside the RC helicopter creates unwanted forces that have to be cancelled out.
3. Direct drive jet RC helicopters are very inefficient. Only 20% of the total power produced by the rotor blades actually goes into turning the rotor blades.

With all the problems present in direct drive turbines, most jet RC helicopter enthusiasts are turning to another design:  two stage turbines.

RC Helicopter Two Stage Turbines

Two stage turbines use the thrust produced by the engine, instead of simply venting it as exhaust. Recall that a jet engine has a main turbine shaft, which is used to compress air and keep the engine running. A two stage turbine leaves the first shaft free to spin, and then adds an additional turbine to the end of the engine, where the exhaust is emitted and thrust is produced. The second turbine spins another shaft, which then drives the gearbox that powers the main rotors. What’s the benefit of using two turbines instead of just one? There are actually quite a few:

1. A two stage jet engine is about 80% more efficient than the direct drive design.
2. Less thrust is wasted, so there are fewer unwanted forces caused by venting it.
3. The engine has to carry less load. Overall, it’s better if the jet engine doesn’t have to directly power anything. Harnessing the thrust produced by the engine reduces vibrations and wear.

The only problems with the two stage design are that two stage turbines tend to be heavier than their direct drive counterparts, and they’re also a little more expensive.

Buying one..

Buying a plane is like buying a car, golf clubs or a tennis racquet. There are subtle differences in them, and the right one for you is determined by your unique abilities and preferences. You are best off talking to an experienced rep from TBM because we can ask the right questions and put you into the model which is outfitted with the components which best fits your needs. We point out an endless amount of variations in the planes, servos, engines, and electrical systems on our website, but we can't put in perspective which advantages outweigh which without a one on one consultation with you. So please read up as much as possible so you have a good knowledge as to what to look for, and then call or e-mail us for our recommendation for you.

Flying Jet Engine RC Models

The model jet engine (gas turbine)

A true rc model jet engine (turbine) adds the ultimate touch of realism to an rc jet, and commercially produced units for radio control use are now widely available and becoming more commonplace.
Turbine rc jet flying has become a big thing in recent years and there are some spectacular models around, but this aspect of the hobby is not for the novice! Endless hours of flying experience and an impressive budget are needed to actively participate in flying radio control jets with real gas turbines. Even the smaller model jet engines can cost upwards of a thousand dollars - and that's on top of the cost of the jet itself, radio gear and all the other bits needed. So it's serious business indeed but ultimately has to be one of the most rewarding ways of enjoying rc flying... if you can afford it!
Incidentally, rc model gas turbines are also used in larger scale helicopters but, from a personal point of view, I don't find these too realistic because of the sound - rc helicopters running on a turbine sound more like jets than helicopters (again, just a personal opinion!).

Shown right is a JetCat model turbine, one of the more popular commercially produced model jet engines readily available. JetCat USA are at the forefront of this remarkable technology and offer some excellent turbine units.

Before model jet engines appeared on the radio control flying scene, rc jets always lacked the authenticity of having a true gas turbine; previously radio control jets had to be powered by either gas or electric motors with a propeller (thus spoiling the look of the aircraft) or noisy IC ducted fan units. Pulse jets were another option but these are more rocket motors than anything else, a pulse jet runs at full throttle for a short time and then the jet glides.
But now model jets can be powered by a fully functional and realistic looking and sounding jet turbine, thanks to manufacturers like JetCat!

How model jet engines work

A model jet engine design can vary slightly from one manufacturer to another but they all work on the same basic principle. The most common type nowadays is the centrifugal flow turbine as opposed to the lengthier axial flow turbine.
The big difference between centrifugal and axial flow turbines is in the stage of compression. In a centrifugal flow unit, air entering the turbine is thrown outwards as it passes over the spinning impeller, or compressor. The air hits against the inside of the can and so is compressed greatly before passing into the combustion chamber. This intense compression increases the pressure and hence temperature of the air, making it more effective when it mixes with the fuel.
The kerosene based fuel, commonly called 'Jet A1', is introduced into the combustion chamber as a very fine mist and so mixes easily with the now highly compressed air. This fuel/air mixture is then ignited by a small glow plug, much the same as the one found on a 2 or 4 stroke model airplane engine.
As the fuel/air mixture ignites and explodes within the chamber the coned shape of the chamber and the incoming flow of new air forces the mixture rearwards towards the turbine; the rapid flow of the fuel/air mixture spins the turbine which in turn spins the compressor at the front of the jet engine (the turbine and compressor are connected by a central shaft).
The gases (exhaust) finally get squeezed through the narrowing jet pipe at the very rear of the engine, exiting at great speed and pressure thus generating the high levels of thrust.
The drawing below shows the basic principle of a centrifugal flow model jet engine:

Model jet engines need to be started with compressed air to initially power-up the turbine. This can be supplied from a diver's oxygen tank or a similar source. Only when the compressor has reached the necessary revolutions per minute (RPM) can the fuel be introduced into the chamber and the engine operate normally.

Scale RC Models

 Scale R/C Models is a new company dedicated to the Scale enthusiast for providing scale drawings, airplane kits, and accessories for kits from the early days of flight to the modern day of Jet aircraft. Its sole purpose is providing, as accurate as possible, aircraft of the different period for today’s scale builder with the scale accessories for completion of his miniaturized dream.  With this in mind, Mike Beaulieu got together with two of friends, Mike Goolsbee and Paul Stelly, both interested in scale modeling.
     Mike Beaulieu has been modeling for over 40 years, from the early Johnny Walker Fireball control line days to todays radio control models. In the early1970's, I did my 1st. Scale control line for ½ A's engines of the P-61 Black Widow and it was published in one of the major model publications. In the early 80's, I prepared the Mylar's for publication for the national magazine " Scale R/C Modeler" and have shipped scale drawings all over the world.
