well i got the motor dropped in last night and it was funny because i went from a 55T geared 21/87 to a 4899kv motor geared 13/87 and there wasn't much of a difference. I jumped up my pinion to around an 18 (i just grabbed one) and now its pretty freakin sweet. It really isn't that fast (relatively) but its alot of fun. It cool to hear the slingers screech a little when i spin out in reverse. I ran it hard for about 5 minutes and then checked the temps. Esc was warm to the touch and the motor was a little hotter, maybe around 125ish. One i get the bugs worked out, i will put a full battery pack through it and see how it does.
Overall it makes for a very very cool trail truck.
I need to work on my front driveshaft this week and get it hooked back up. I am having output yoke issues with it.
