I have a Moki 2.1 on a new GP Wagstaff Extra. Current prop is a Menz S 20x10. I was curious if anybody has tried the APC 20x10 on this engine and a simliar airframe and how did it compare to the Menz? Also the APC 20x10 comes in two blade configurations, the 20x10 and the 20x10W. Is the 20x10W better suited to IMAC style aerobatics with this engine than the standard 20x10. I don't do 3D so acceleration is not a major issue. My concern was whether the Moki has enough torque to pull the 20x10W. The Moki has only about one gallon of fuel through it for break in and I am turning the Menz at about 6800 rpm with a measured 20 lbs static thrust. I was expecting more but maybe these figures will improve with more break in time accumulated. Your thoughts??

The Mokis Have a very hard chrome piston/cylinder and you are not fully broken in yet. You will see Max power after another 2-3 gallons(or more!) It took about 5 gallons in My Moki 1.35 to Peak with my current prop.

Yea, that's what I hear about 5 gallons to max power. Nobody has tried an APC prop on this engine???

Have Your RPM's improved yet? how many Gallons?
