have you tried , trimming the throttle down , it might be on throttle even though the stick is fully down . also . check your channel to see if the throttle is not reversed .
usually the ESC IS A DUD when this happens . ive came across 2 faulty escs in 6 months .


if that fails , turn your transmitter on 1st with throttle on full , then the rx and esc , wait 30 seconds and pull throttle back to stop , and trim down . it might work then .
