Thank you guys very much for your replies. It definetely helped. However, I am still unclear why the fourth channel is required on all the glow trainers I looked at. Is it because it is standard for glow trainers to have ailerons?

To answer your questions as to what kind of radio I have rcflyer, is that in a nut shell I dont have one yet. The plane I am flying now is an AEROBIRD, but its kind of a generic radio that comes with it, its 3 channel. It has a mixer, but.... I can only use it with the AEROBIRD, so I do need to buy another. I am pretty sure I will buy a 4 channel, maybe a 6, but probably a 4.

When I first got the AEROBIRD it was on the ground more than it was in the air. But its only been a couple months and now it has become easy. I am just afraid that when I get a glow trainer I will be starting all over. And I know those basa wood planes do not hold up well to crashes. But I have learned quite a bit with the AEROBIRD.

My plan is to get a glow trainer. I will learn to fly it, hopefully without destroying it go badly. Then I will have a 4 channel radio and engine. Then I plan to buy a kit and build one why I'm learning the trainer, because I will already have the engine and radio. All I should need is some servos and maybe a couple other small things. That sound like a good idea? I have seen pretty cool looking kits for under 100 bucks.

Thanks,

Wings
