Super fast lightweight 3". Can't wait to get some more of the 1404-4850 Superman motors.
I like the simplicity of the all in one Zeus. I may be at the limit with the 4s and 3850 on bi props. I'm not sure I want to try tri-props on it, but for racing they are not needed since most of the throttle is in upper range anyway. Thrust test show the bi-prop has the same or more thrust with less amps at the higher range anyway.

Some laps on the track... .
