I’ve got a temp checker I used for nitro rc, I think around 60•c is about the highest you want to be at you could try Gearing down May help ? I've just procured a Losi scbe last time I bought and sold it it had the dynamite fuse motor which got hot. I bought this as a roller and shoved a surpass hobby 4300, but it whipping the Arse out of the battery run time running 16t pinion I gone down to 14t it seems to running a bit longer. And cooler .What is safe motor temp? When should I let it cool before running again?
