Spare propeller

I bought this as a spare propeller for my Critical Mass electric airplane. It looks great and I'm sure it will perform just fine

Critical mass propeller

Very scale looking and works great with the hot up modification's I made,keeping the scale look and gaining a lot more speed.

great

I love this prop, it fits on several of my motors for my planes and is highly effective for the speed I like to fly.

Great props.

These props are great for an upgrade to the new EFlight P-51 Mustang. I stuck a EF Power 25 1050kv motor with a 60 amp ESC with the Critical Mass Prop and I'm clocking 80 Mph+ These props are amazing.

Keep a few of these around

Good prop, gives you lots thrust with four blades. It takes a beating but will break if you have a tip over on landing.

Better than the durafly prop

This is almost an exact drop in for the durafly 10.5x8 prop used on warbirds. I used this on my 1150mm airfield p51, and also swapped the motor and shimmed my custom motor mount. Prop worked great! Strong, flexible, and survived a nose over on the first flight where a durafly prop would have snapped. You can feel the difference in quality when you have them both side by side. Order several as backups, but you won't have to replace them as often as you would a durafly prop.
