It took about 4 gallons through mine to get it as good as it probably will ever get. The trickiest thing in my case was that dang low-speed disk. Tuning the Moki turned out to be the most trying experience in R/C for me.

I've tried plugs: OS8, OSF, Enya3 (the best, very hot)

I've tried fuel delivery tweaking: Large diam. tubing, drilled-out clunk, even a check valve! (No change)

I've tried fuels with/without nitro from 0 - 10% (No significant difference although the needle design likes FAI)

At this time:

1. No deadsticks, GOOD!

2. Transition on the ground good; however it sucks big time in the air! As soon as the plane speeds up during the takeoff run, it sputters as you advanced that throttle! Figure that one out!

3. As soon as it is in the air anything below 3/4 stick is way rich, and if you roll it inverted it becomes richer. HOWEVER, IF YOU LEAN THE DISK ANY MORE THE ENGINE WILL CUT ON TRANSITION!!!

4. EXCELLENT IDLE

5. EXCELLENT, MUCHO POWER at the top! (Hovers a Sig CAP 231EX!)

6. Since it doesn,t deadsticks I will keep it.
