Just adding my first post here. I really like the Tiny Trainer, and have graduated from three to four channels with the aileron wing... I can say using the high/low angle template and expo for control surface throws was a big key for learning to fly. Much easier to learn on the low throws ... Just my $0.02 Also, I had to move by battery back to get the CG right. Great plane for me, and a really good build and fly experience.
