I'm thinking of naming my plane "Do & Re-do". Ten days ago in Pensacola, duh?, I set about to re-evaluate my mixture map. (hint to Perry)(Thanks to Ed). I found that the average setting, from 13" to 30" was 5-6 bars/10 on the meter. I reset in Mode 1 to 7-8 bars. Went flying and power was good. However, takeoff roll rpm was still low at 4500. As we accelerated to 5400 in level flight, the mixture meter showed only 4-5 bars. I adjusted to 7 and kept the mixture there for local flights at from 3-5000 with nothing but smoothness. Questions: 1.Why would the WOT mixture decline in flight vs. static WOT? 2. Should I go for more TO power with slightly less pitch until it will generate 6000 +- with WOT in level flight? Regards, Tommy the lurker ps WOT Temps never got above 197* with OAT at 60-65*, even at 80kt climb Rusty wrote:" Speaking of learning, it's frustrating to make so many mistakes ...... a way to do it better the next time.
