A couple of quick questions to the Moki experts:

1. Does higher nitro increase rpm/thrust with the normal IMAC style props used on this engine? I am running 10% nitro, have not tried lower or higher nitro to check the effects. with fuel costs what they are, I want the highest possible cost to benefit ratio.

2. Bisson lists two muflers for this engine in the Pitts style. One they call the high volume style and the other they call the low volume style. Does anyone know the difference in power output between the two???????

3. I have the low volume stlye Bisson Pitts muffler, what is gained by cutting off the muffler tips like some of you guys are talking about on this thread?

4. I have 4 gallons through this engine so far and I am taching 6660 rpm with the Menz 20x10 prop on 10% Omega fuel. You guys are getting way more rpm than I am. I'm starting to believe I got a dud or someday stuffed a shop rag in my intake. It could also be the Menz prop is less efficient. In defense of Menz and Moki, the combination is pulling my 14 1/2 pound Patty Wagstaff Extra straight up out of sight without even slowing down. Also the downline braking is awesome, it almost stops in midair when you chop throttle. Anyway, has anybody else tried the Menz on this engine, I want all the thrust I can get out of this critter.

5. Where can I get the Moki 2.1 prop everbody is talking about and how much?
