All,
I crashed the QQ Yak thru no fault of the motor just me being stupid. The 3W-50I has sat for three years and not run. I have been flying 80-100 cc planes and now I have finally come back to 50cc. Pulled the three dubya out and installed it in a new Wild Hare MX-2
and ran today on a 3W 22x10 wood prop.

Temp 80 degrees
humid 54%
wind calm
3W 22x10 wood 6600 almost 6700
idle 1600
32:1 Penzoil Aircooled

Also ran a DLE-55

Biela 20x10 three blade
6800
1600 idle
