Some props have the 10x4.5 R marked on the top side, sooooo the "R" meaning reverse (CCW)? Also is it safe and can I run 4S batteries with the 10" props? The 3S batteries seem to not have enough power for the 10" props. As a matter of fact the F550 running on a 3S system seems to be very short on power. Mayeb its just becase I come for a super powerfull T-Rex 500 the really thumps in power. so please correct me if I'm wrong and I will shut the heck up.
