Moki 1.8, its up to you. I ran mine 2 hours on the ground and now after 4 gallons I'm getting 7650rpms on a 22x8 JXF. Did your needle settings change yet?
I have two DL-50's running 22X8 JXF. The most I'd get is 7.1krpm. That's enough to pull my 17.5lbs Extra vertically out of sight at takeoff. And yours turns 7650?
