no pitch change for Pit's RV9
Thank you Guys, very good comments, advices and good ideas ....
The prop is overhauled, balanced, blades alligned, it looks like new. The best picture of my problem was represented by one of your comments which sounds like these
"If full throttle at cruise altitude is possible without exceeding 2600rpm ...." or that one "Is a lot of your high speed cruising time spent in a condition that you have to pull the throttle back" or this clause "have you considered the 'total' performance gain of adding one electronic ignition" and this one "Sounds like you have a good combination now."
A RV9 O320 with a Sensenich prop pitched 79" does not exceed 2600 in the cruise ... and so does ours. Now she runs much smoother than before. And yes, she has got two Pmags which are indeed responsable for the smooth run generally.
Thanks! Pit
