All depends. I love the Giles 300 for 3D tumbling maneuvers and gorgeous steep elevators. I love the Caps ability for high alpha knife edge, as well as tumbling maneuvers. I love the Extra 330s for blenders, flat spins, inverted elevators, flip-flops and walls. I love the Edge for its nimble characteristics. I've only flown the 42% Yak-55sp once, and didn't really get a chance to 3D it, but it was the nicest airplane I have flown in a long time.
Can't I just get one airplane with all these rolled up into one??
