So I hve decided to change motor for LRP Dynamic 8 2200Kv (2370 watts) with 14 pinion, final internal ration is 11,12.. So motor has much more power and ratio is lighter. I hope thanks to this I will solve troubles with overheating and get the same or higher speed as well. Now I am still waiting for smalller pinion (14) and then I'll see

Regarding to ESC, do you recommend replace stock ESC for something "better"? Anyone has experience with stock ESC and hobbyracing?
I thinking about Skyrc Toro TS150A... Does it make a sense?
