What is Gas RC trainer airplanes
Gas rc trainer airplanes are typically designed around the '40' or '46' size (.40/.46 cu.in) 2 stroke glow plug engine, and are 4 channel with control to throttle, aileron, elevator and rudder. The wingspan will vary around the 60 inch mark.
The planes can be purchased in kit form or RTF/ARF (Ready To Fly / Almost Ready To Fly). RTF airplanes are the better choice if you have no desire to do any model building, and you just want to get flying as quickly as possible.
The primary differences between kit, ARF and RTF are:
- Kit: the plane needs building from plans, you'll need to purchase quite a few extras and have a good knowledge of model building techniques.
- ARF: the plane will be about 80% finished, needing some final assembly work, taking maybe a couple of evenings to complete.
- RTF: the plane is completely finished, with motor and rc gear fully installed. You just need to buy batteries for the rc gear.
