Larry,
The throttle system you describe is normal for the Rotax two strokes. The cables
are pretty robust. I do not know of any failures in flight. I have and prefer
a friction type throttle. I don't like the vernier either.
That Horizontal stab/stick/elevator position is odd.
Two things come to mind. An adverse aft center of gravity and/or the flaperon
rigging is out of wack. Did you have to hold forward pressure on the stick for
level flight?
