I am trying to optimize my prop pitch in search of the perfect setting for cruise and climb. I was making about 5400 rpm on climb out, which gave a good climb rate but I could pass redline at full throttle in level flight. 5000 rpm gave about 95mph and 5500 close to 110. By the way, I have a Model 4/912ul with 22" Dessers. I added 1 degree of pitch. It gave a big boost in cruise but now only making about 5000 rpm on climb out. It still climbs good but my concern is am I lugging the engine. I know Rotax says not to overprop. What's the opinion? Should I remove 1/2 degree? James Thomas
