I purchased the hobby wing max5 esc with the 5687 1100kv brushlessmotor combo for my traxxas xrt. I have the traxxas 6700 lipo 4s batteries. I had to change the pinion gear 32 tooth and 47 spur it quit after two times running it first time 3 mins not hard. 2nd time 50 tooth spur gear never got a chance to open it up to full throttle. The esc quit sent it back and was told i overheated the esc. I thought they had overheat protection. I am getting a courtesy esc from hobby wing. My esc never shut off i stopped the truck and when i went to take off it wouldnt go. I got the gear ratio from online people who have same setup.anyone heard of this?
