How to slow down the buggy ? dualsky 870tf
 

My 2wd buggy is bit too fast for me to handle.. its running 6.5t x12 motor on dual sky 870tf, i got programme card.

How can i slow it down like it is running 7.5t or 8.5t motor without changing the motor for slower ones? what setting in esc?

Try turning down the end point on your transmitter?
