Old thread, I know
TT Pro 46, stock muffler without the baffle. 7% Fly High Power (Cool Power), APC 11/5, OS#3 plug.
Idle 2500, top 12500.
No increace in RPM without the head shim.
Edit: With APC 10/7
Idle 2500, top 13300
If you look at the attached picture (from
www.mvvs.nl), you can see, that the thrust with the 10/7 prop is a higher that with the 11/5 prop. I guess I'll stick to the 10/7, or?
