Started mine yesterday for the first time. Used my reg. nitro electric starter. With no adjustments to the carb it ran well. It idled at 2300 and the hi end was 6400 with a 18x6 prop. I flew the plane for about 10 mins very rich. Landed and ran the rest of the gas out. The idle smoothed out even more and the Hi end was 6990 still with no adjustments to the carb. It ran very good right out of the box.
This is the one I have.
