I hooked up an older GTB esc I have, and it worked fine. When I steer the buggy, the motor cuts out and kicks back on after a couple seconds, though it still retains steering. I was testing it on the bench and steer the tires back and forth a few times the red and amber LEDs on the esc start flashing which is saying its going in to low voltage cutoff. Just wondering what's going on here. Is my esc junk?

Also, the car is a Losi 22 and the servo is a spektrum 6030 high tourqe digital. The motor is a new Novak ss13.5.

Your servo is probably drawing to much juice and causing it to glitch. Try putting a capacitor on your rx.
