I have 25 planes, and I still take out my Telemaster! It's a great plane. Instead of the nice slow landings for a reason to fly it now, I like how it flat spins extremely well, and pulls out 40 feet from the ground, every time. Can't get away with that on my other planes. Telemaster requires kit building I think, I've still seen it around. LONG wingspan helps slow them down. How about the worst? Flying school bus trainers, which have too much dihedral.
