FWIW, I've decided to run the standard 30% Morgan heli fuel until more time is out on the motors in general. I'm not sure what the value of running less oil is at this point (besides less of a trail). Flying my 170 CDI back to back with Juan's Brio/170 standard, there is a a big difference in spoke trail already (mine is reduced versus the standard). With the Mezjlick 18x10, I set the idle to 1700-1800 rpms, and top end was 8640. If you set the idle any lower, it starts to mismatch the throttle curve because now you have to move the throttle stick some just to get into the usable power band, then all of a sudden the power starts coming on. At 1700-1800 rpms, you need a higher degree of stick pump to go over stall turns nicely (perhaps though that is just my poor technique).

At the end, I adjusted the idle in the 1700-1800 range, and the curve so that it is "steep" in the beginning, then flattens a bit to the top. I also took 25% off of the Throttle AFR and was still achieving the 8600+ rpms. So, this leads me to wonder where "full-throttle" really is on the thottle body. Attached are some pictures of the servo and barrel at 100% and at 75%. The original 100% position was short of exactly 90 degrees on the barrel. There is a noticeable difference in the 100% and 75% positions. Also, the pump screw is just barely out from flush. The high-speed needle is about 1 turn out.
Thanks,

Can anyone else describe their pump position? I think this is where some people are seeing higher fuel savings than others.
