I'm using a teu101bk on 8.4v with a Graupner Speed 600 8.4v motor. The ESC is overheating on continous full throttle. Does anyone have any experince of putting a water cooler onto one of these controllers? I want to know if it would be worth attempting such a mod, or simply upgrading to a new controller. Thank you

I would recomend getting a new one. Get the Robbe Navy 535r 35A or the Jeti 600 navy if you dont need reverse.
