Warbird.... I don't think it is the angle at which the turbine is causing your problem. When you think about this, If the turbine is pointing at a slight angle (front down 3 deg) it is pushing on the rear of the plane down, which in turn would cause the noise of the plane to go up at higher thrust. Just the opposite if you had the turbine thrust angle pointed up to where the front of the turbine is higher than the rear. That scenario is trying to pull the rear of the plane up and inturn push the nose of the plane down.

I would be checking the CG of that plane to see if it wasn't a lil NOSE HEAVY. Also, where is the bulk of the fuel on that plane? Is it ahead of the cg. Could it be causing a nose heavy take off. U2Fast and I experienced a real nose heavy facet this weekend that was very close to not taking off on its maiden. I think the cg was about 1-2 inches ahead of where it should have been. U2Fast was flying it with full uptrim and about 3/4 of the up elevator just to keep it flying level.

Somthing else to check would be the angle of attack that the plane sits onthe ground. Is the nose a little lower than the rear? if so... try to get level if not a slight nose high angle of attack. That should help a bunch.
