thanks alot for all the help. If this site would have been around 15 years ago I would probably be giving the answers. Its great!! As for the radios iv decided to buy a 4 chan with feather receiver and servos. By the time I buy the receiver and the servos for a few more bucks I can have the trans too! That way I don't have to swap the one feather I have around as much. Lots of fun building arfs. mostly on my butt.
