RE: Looking For goof Trainer
The SIG Kadet II ARF is a very good plane to start with. Also, Tower Hobbies has an ARF trainer that is Guarented as long as you learn with an instructor.
As for the specifics, a "high wing" .40 size plane, with a 4 channel radio and a .46 size glow engine is a great way to begin. Here are my thoughts on my suggestions...
4-channel radio: Ask any pilot at the field, and he will have at least one 4-channel radio. No matter how long you are flying, you will have a need/use for the 4-channel radio.
.46 Glow engine: If you fly off a grass field, the .46 will help pull you through the high grass during the spring season. Stick with the glow planes to begin with...sometimes the electrics don't have the power needed for high grass/high wind flight.
Just a thought.
