RE: Master Airscrew Props..

Actually, almost all the lighter cast reinforced props like APC and MA flex to some degree. Some more than others. You won't see the APCs doing it because they have such flat incidence from about...

RE: Master Airscrew Props..

My Extra300 is 6lb 15.5oz, or was with the OS61FX on it. It flew very good with a number of 2 blades. If I remember correctly, the TF wood was the best 2 blade. A MasterAirscrew 2 blade was just...

RE: Master Airscrew Props..

If your 12x8(3) Graupner seems to be too much load for the Saito, if I were you, I'd take the 13x8(3) MasterAirscrew back, tell them what it was doing and see if they'd swap it out for you. And see...

Not "bad".... human.

I've run a 13x8(3) Master Airscrew for a couple of years on an OS 75AX with more than excellent results. I actually run it "alternately" with another 13x8(3)MA that I...

RE: Master Airscrew Props..

A 12x8(3) is going to be a better choice than a 14" diameter, at least a better bet for a test. Your Saito is probably about as powerful as the 61FX/75AX averaged.

I found my OS61 two-cycles...

RE: Master Airscrew Props..

The last time I ran a 4cycle (I don't use them very often.), I made a mistake in handling and it beat itself to death. ;)

OK, I'm making fun, but that is actually true..... except for the...

RE: Master Airscrew Props..

They apparently haven't made or marketed that prop dia/pitch.

I'd say there is a possibility you bought a counterfeit.

There is nothing about the dozen or so Master Airscrews I've bought...

RE: Master Airscrew Props..

The old packaging and the new (just bought last week) packaging don't list your prop as one Master Airscrew makes... or at least sold or sells in MA packaging (old and new packaging) in the US.

RE: Master Airscrew Props..

RE: Master Airscrew Props..

I run 14x7(3) on OS91FXs in my P47, Corsair, Spitfire, F6F, and Sukhoi. They pull excellently well. As you would with conventional gear, I've had at least a couple of slight prop hits this summer. ...
