RE: Slower prop for T-34?
There's no reason someone who's mastered a basic trainer can't fly one of the sport scale t-34's. I have one.......the airfoil, aside from being a bit thinner than, is not to far away from a four star or tiger, certainly less forgiving than a U-can-do or a something extra, both of which were recommended to me by instructors for possibilities on second planes.
The idea of scale is an odd thing.....generally it's a no-no for a newer pilot, bu this plane is one that's doable.
