RE: Slower prop for T-34?
Hmmmm You joined RCU 8 months ago. Doesn't mean that you have been flying 8 months....
Gone through 3 trainers? I've never seen you fly but if all you have flown are trainers I don't think you're ready for the T-34 either.
For all the things already mentioned.
Never used more than 1/2 power? why?
