the model flying upright, straight and level."

Look at the horiz. stab. It is mounted incorrectly...being that it is glued
onto the top of the fuse, at the rear....with a wild up angle. [X(]
Normally it would be mounted at the same angle or incidence as the
wing....however, in this case....being a flat bottom trainer type plane,
the wing shoulg have about 2 degrees positive incidence at the front.
(about 3/16" will do)

That's why you have to give up-trim for level flight....and that trim is
making the inverted flight even worse.
