Subject: 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.
