it worked the 1st time but when i tried 2 run it again the led lights up when i hit the throttle but nuthing happens...steering works still..but it also flashes sometimes...and in the manual it says 2 push a reset button but theres not 1 there! what do i do

Uh....Get a sidewinder package! Those cheap China ESC's crap out really fast. Did you put a 7cell battery in? Anyway get a SW because the diffs can handle the power and put a big smile on your face.

how much is it and where can i find one

will it work wit the stock buggy motor

NO! If you get the package you get a brushless motor too

o well i jus got this thing yesterday for a gift so could a hobby shop put it in?

Power and exceed don't mix.
