Must be like the Brusheless Gimbals BG-10 model, thing is BG 10 its less half the price and handles my RED Epic like a champion! ( 32 bit Upgrade Version)

IMO I used M5 before, the only difference I found is their quick release and auto tuning are superb. Other then that the rest are the same provided you make sure your structure, balance and tuning are almost prefect.
