I have a Tacon 3660 2200kv running on 4s in my SuperVee 27. Quite a boost in performance. Found a X637 prop is working the best for me so far. Running a stable wet hull at 46mph (gps) with motor temps around 100f after a 5min run. Using the 60a AquaCraft ESC out of my UL1. Great motor, many runs so far.
