Our Club has dove into combat head first we went from 1 club member having combat planes to over 20 within a month, most of the members have TT .15's and the reviews are awsome. The LHS did have some of these safety nuts that were modified from a different safety nut in a machine shop custom for the TT .15, but they are out .

Does anybody know a good source for the Blue MAS 8x3 prop used for SCC?
