Hi All,
I am so glad to read Rusty's honest appraisal of how it really works in
this experimental stuff.  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
