RE: Anyone got readings OS Fx 91?
Just tried the FX-91 with 4 different 16x6 props. All with 15% Power Master and standard muffler. All are peak RPM (I wouldn't fly at this). Trust is static within minutes of each other.
MA "K" Series - 8850 - 11 lbs 12 ozs.
MA Classic - 8600 - 10 lbs 15 ozs
MA Scimitar - 8500 - 11 lbs 0 ozs
APC - 8600 - 11 lbs 5 ozs ( this may be low - will retest - think it s/b about the same as the "k" in RPM & Thrust))
MA "K" Series - 8850 - 11 lbs 12 ozs. ( repeated test)
This FX-91 is brand new - looks and runs great. Haven't tried any other props.
