Re: REFLECTOR: SVX & IVO Prop...rigging
I'm approx. 4.5" above the center line with my thrust line.
Last time I talked to Dwane about this he suggested I try it like it is (1
degree forward) before making any changes. He also said that the reason they
start with about 1 degree forward cant was because after the engine settles in
after running for a while they sag sometimes 1 degree. In any case, when
we do our high speed taxi tests we may get some indication of a problem if there
is one. We'll keep a close eye out for a nose heavy tendency during our
tests.
We haven't rushed anything yet with this plane and don't intend to now. My
guess is that 4.5" offset is not enough to cause a problem, but I'm
not going to bet my life on it. It flies when it's right and not before then! I
certainly appreciate your comments and suggestions and will keep the group up to
date on our progress especially now that we are getting closer and exciting
things are happening.
