My favorite is the balsa USA stick .40 I learned to fly with one, and have taught others as well. I think there are a lot of good trainers out there and there is no one plane that is the best . the old-timers I grew up with Had a different choice of trainers than is out there now. years back
arfs were unheard of. Sig, Goldberg,sterling, balsa USA, and many others made good kits for trainers. A lot of which I have flown. I have also recently purchased a falcon already built and it was a very crappy job of building can't even say I had one good flight. The end came when the firewall tore loose when I was ready to take off. the moral is, even with this type trainer model. this plane would not have been good for anyone. but the falcon IS a very stable plane when built and setup correctly
