All,
Update
Switched from Pennzoil Air-cooled 32:1 to Red Line Synthetic at 40:1
also switched to 3W CF 26x12 two-blade prop. While noise has greatly increased with this propeller the climb and performance have also greatly increased over the Biela 26x10. Turns the 3W propeller at 6000 even. Doesn’t seem like it but this is a great 3D prop.
