I purchased one at the IIC. I am using it in 12th scale. Performance-wise, it is pretty solid. As with all motors, you will have to hunt for the sweet spot, as it differs with all motors. However, it isn't much different from other Fiego based motors that I have tested. I turned some of the faster laps (if not the fast lap) this past club race.
With the venting, it seems to run cooler by about 5 deg. However, it does open it up to debris.
