Master Airscrew GF Series 7x4 Performance Propeller

So you've been using those cheap 6-for-$10 Gemfan props for a while and you're finally getting tired of them breaking on featherlight-flare perfect landings, right? Well, Bunkie, this is the prop for you! Not only is it strong enough to survive hard landings, it does not flex like the cheap props and delivers all of the thrusty goodness you need to impress your girlfriend or your neighbor's dog, whichever happens to be your observer pilot the next time you're flying.

i used them on my .40 motors for ages

Very happy with this propeller, works well on my airboat.

Product is good but was expecting a quantity of 12 as described in the title.

Great upgrade! 10x better than cheap plastic more durable then wood. Price is good too..

Great replacement for the one my buddy exploded when he tried landing the junky trainer I keep around for laughs. Fits and balanced on an OS .40 just fine. Have yet to test impact resistance, but the prop seemed a tiny bit softer than the poor APC it replaced.On the flip side, being pitch black it tends to disappear easier than the bright grey APC. So be careful and mind your hands around nitro powered finger killers as always :)

These are not the same Master Airscrew/Windsor Prop 7x3 props I have purchase in the past, currently comparing them to my older Master Airscrew/Windsor Props and these are flexible unlike my same old MS windsor props that are stiff. ... not suitable for my D2628/d 2200kv motor these will flex and make crazy noise at that RPM on 3s ... going into the trash.Picture shows 2, description has 12 in parenthesis "Master Airscrew/Windsor Propeller Nylon/Glass Propeller 6 x 3 (12)" so how many are their? Just 1 prop ... -_-

Excellent product
