Downthrust -- I need expert advise
My elevator is in neutral position with the trim control in the middle position. If my airplane (J-3 Cub) wants to climb all of the time even when I try to trim it, is the problem:
1 - Too much downthrust?
2 - Not enough downthrust?
Will the answer change if my airplane has wings on the bottom, like a P51?
I'm getting conflicting advise on the subject from experienced pilots and I would like to know what the proper answer is.
Any help will be greatly appreciated.
Thanks,

RE: Downthrust -- I need expert advise
Doesn't matter what wing configuration - in a tractor aircraft, 3 degrees downthrust and 3 degrees right thrust is typically used to mitigate the "nose up", and "torque effect" (left wing down) problems.

Dr Kiwi,
So, based on your comments, the answer to my question is No. 2 -- I don't have enough downthrust.
Is that correct?
