hi i just installed the 17 tooth pinion for a bit of fun out the front on the road. now i got mega fan installed and esc fan but after about 15 mins of straight hi speed runs with trenchers balloning like crazy. i pulled up to a weird smell i touched motor cool as a cucumber same as esc fins. but my battery was pretty warm and pretty sure that was where the smell was coming from here is a photo of battery only 2s 30c 5200mah can some one please explain if you know what might of made it happen and after 10 mins unpluged smell went away and battery good now.
but that pinion opens it up some thing stupid
