A little expensive, but good product.
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
Very scale looking and works great with the hot up modification's I made,keeping the scale look and gaining a lot more speed.
This is a good looking and good werking prop. The only down fall is it brakes to easy.
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 prop for the price, buy extras for you first few flights. Motion Rc is awesome in customer service!
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.
Good prop, gives you lots thrust with four blades. It takes a beating but will break if you have a tip over on landing.
