Hi Dave,

I've got a new 110 with about 2500 cc of 25% nitro fuel though it now doing the break in. So far, I've found that as you've said here on the forum, the 16x4 prop recommended for the Funtana won't hold this little horse even at this 4500 ft. ASL and about 85 degrees ambient temp.

So I've got the 16x6 prop on it now and my question is that wide open it will spin at about 9200 RPM, but if I close the throttle just a hair it will wind up to almost 9500 RPM, open the throttle all the way and it slows down again. I've followed the procedures for setting it up and the idle, mid-range and transition are all good, but I'm curious about why this is happening. It would seem it's a touch lean wide open, so is that possibly a regulator setting problem?

I'm a newby at this model engine stuff, but I have a bunch of experience with full scale piston and turbine engines, so I'm still trying to learn these nifty little engines.

Thanks,
Zeeb
