I realize you are only using 10%, but has your RPMs on the APC 16x6 improved any?

Status: offline 		Think I gained about 200rpm after the bearings where changed. I say "think" just because my engines also turn more rpm sumer time which is now. The rpm change can be as great as +200-300rpm in hot wheather and thinner air compared to winter time and below 0-degree celsius. I also use a dubro 45-degree exhaust deflector that keeps the airplane clean but probably cost me 100-200rpm or so.
