An update,

I went and bought a fish scale and set it up behind the airplane and tried 3 different props for thrust tests. Here are the results. You should know that the propellors used were generic Zingers, not the pro series or any fancy props. Weather was 87 degrees with 90 percent humidity at 100 ft above sea level.

Size RPM THRUST

22 x 6-10 6000 18LBS

22 x 8 6300 19LBS

20 x 8 7700 18LBS


I have only flown this airplane with the 22 x 6-10. I guess my question would be..which propellor would work best??
