There's no logic to acquiring more planes. I have to stop myself because I have plenty of planes to fly. Do I want more, yes. I always see the next model I'd like to have. I've seen the Parkzone Corsair fly. One of the guys in the neighborhood flys one at the park. It's pretty cool. Would you benefit from it? Probably. The T-28 is pretty cool also. Or even the Super Cub could have training benefits. But I will admit that I get the greatest joy flying the same plane over and over and over. You get a real good feel for a plane when you do that. So maybe a second plane is a good idea, whatever you do, get as much flying from whatever you have.
