Excellent motor. I did a careful break-in for 4 gallons of 32/1 mix on a test stand. Motor is tight & shakes at first but starts to smooth out after a couple gallons. Flying in a 32 1/4 lb. bipe with smooth pipes. It rips a 29 x 9 Falcon prop. Needs more prop. I have over 7 gallons through it now ... runs very smooth plus awesome power. My new favorite motor.

Just test ran and got one flight on this engine, out of this world, was easy to start and while setting the mixture screws, one flip and the engine started every time. Going to be great.
