Every design contains a series of compromises. The 727 had a t-tail. Was it for performance or because the exhaust of the Fuse mounted engines was in the way of a standard tail? What part does structure play in the decision making compromise.
Most commercial aircraft have the horizontal stabili

1. Is the hook solid in the bottom of the plane?
2. It sounds like the plane is nose heavy. (4 clicks of down trim flying fast but flew fine with out the down trim in a hand launch)
3. Hang the plane upside do
Yea - sounds familiar.
Check the longitudinal balance.
The left wing might be heavy. It doesn't take much to cause this problem.

my memory of the Condor. First thing I see is a plane with almost no LE
