Title: Master Airscrew 3-blade props
Post by: Kim Mortimore on January 31, 2011, 08:13:23 PM

I'm curious if anyone has tried these and how they compare to APC 2-bladers.  I understand that the pitch ratings are quite a bit higher than actual.  The fields I fly at are brutal on carbon props, which are beyond my budget anyway.

Thanks.

I've used a 12x5 3 blade Master Airscrew a couple of times. I re-pitched it to about 4" and used it a bit. Seemed to work fine, but I haven't experimented further. Pat Johnston is sort of violently anti-three bladed props, but weirdly, he turned me on to it.
