Thanks all, Once I get the spinner weight/CG issue settled, then I'll tone down the throws. Chris, I thought I'd start at 1/2 of the rec. throws and gradually decrease as needed, and then I saw your post. Bingo! I have several different 9" props that I'll put through some test flights. What type of spinner are you all using? The plastic cone-type is not my favorite. Tru-turn or spinner nut?
