Hubb,
Thanks for your reply. Yeah, at a hundred bucks a pop, I want to make sure that the top of the backplate and the front/top of the cowl line up, and I know to leave some room at the sides for thrust adjustments. Did yours need any? Then again, I will be running a 27-10 2 blade versus the 3 blade you were running. My experiences have been bigger props seem to need a bit more thrust offset. Thanks for your feedback.
