When I decided to go to RC I just built a two ch. 1/2A cub and used one of my old free flight Tee Dee engines with a home made two oz. tank. The Hitec radio and servos were about 65 bucks. That got me into RC for just a taste over 100 dollars. Only tools I used were a razor knife and sand paper, I did borrow a covering iron and heat gun. Dosn't take a lot to get into the hobby. Things just seem to add up a lot with time.
