I would personally reccomend the aircore 40 trainer. It is an easy plane to build and fairly easy to fly. Also a good thing about it is the fact that it is nearly indestructable. I have crashed mine with full throttle and it only required about an hour's work to repair it. Lastly it is very cheap, to build and fly. My website
www.geocities.com/rclinks2002 under "My Planes" has the story that I wrote about the plane. Have fun.
