I'm using a DA50 on my yak,I have put 3 gallons of breakin fuel and oil through it.Now i'm running my 100to1 oil mix.
I"m now wondering what rpm number i should be expecting.
I'm at sea level and its about 85 to 90 degrees,I'm using a NX 22x8.
RPM is around 6500.

Thanks guys

Status: offline 		DA 50R, stock muffler, Xoar 22 x 8 prop, peak lean 7360, 7200rpm ready for flight with good transition. 85degrees, 500 ft. msl. Lawnboy 32:1 with almost 4 gallons run through. Plan to go to a Vess 23A prop, but might settle on the 23B. Heard a recommendation today to go 24 x 8 with MSC cans. Don't know about that one due to weight.

While break-in my DA50 with ashless 32:1 in 1st gallon of gas, I got 6900 RPM on the ground with Mens 22X8 @ sea level.
