FWIW, I am running the GT 2.0 Pro in a DESC 410R and love it so far. Handles the power of my 4.5 550 motor easily, even in heat above 90deg. Just started selling off all of my old escs and will be converting everything to Speed Passion. Super smooth, great power, and excellent feel for both throttle and brakes. 2 thumbs up!
