On a completely unrelated note. I was wondering why a two point rear
stabalizer mount is used with the combined engine mount psru aapter. It was
mentioned that there was a bending moment on the ends of the plate and that
during a flight test drop onto a runway some bending had occured.Obviously
we don't design for this operating condition, but for normal use. It just
seems that if the stabalizer mount that was a three point triangle it would
help counteract gyroscopic loads from the propeller at increased angles of
attack like for climb. Are we just inheriting the two point link from a
previous successful installation without necessairly evaluating it, or is
there some not obvious reason other than weight concerns.

I don't recommend a two point rear stabilizer mount.
How did you get that impression?
I recommend a single rear engine mount.
Which photo did you see that in?
Can you email it back to me?
