Introducing the latest addition to the Armattan Oomph line of motors, the Velvet Edition!
The construction of these motors was carefully selected with smoothness in mind. A lot of motors offer insane performance these days, but that usually comes with multiple drawbacks. High amp draw is the first concern. Noise and vibrations making tuning a more tedious task is another concern. And of course, if you have noise on your build, or if it is not well tuned, it affects HD footage greatly.
In other words, really high output motors are not suited for freestyle flying. They are better for racing. Flights are too short and the footage is only "OK."
-Low amp draw. Check!
-Low noise. Check!
-Low vibration. Check!
Results: Easy to tune, smooth as butter, and crisp HD footage.
With Armattan's innovative design changing props is easy. All that holds the propeller down is a standard M3 bolt and washer combination on the top of the motor. Once the bolt is unscrewed, the propeller and washer will slide right off of the smooth shaft. Gone are the days of fighting to pull off a blade-less hub and coming away bruised and bloodied. Besides eliminating binding, the Oomph motors have a shorter (lighter) shaft and require only a hex-key (Allen Wrench) for a prop-swap.  Another added feature of this solution is that you can tighten the prop-bolt much tighter without fear of stripping anything. This means you don't need to worry about fitting locknuts in above the prop or getting shafts threaded in the proper direction.
