Review on Rustark Diameter Mounting Resistance Reduction by Dave Brummet

Bracket, the part I needed the most works great. The clutches were a bonus but don't work for me. I need a 6 to 7mm and there is a 6 to 4 adapter that comes with it. I was also disappointed that there were no mounting screws for the bracket, just connectors. The kit is fine. If you already have the propellers for the motor and the clutch is right for your needs, this could be an asset.
