my setup as of now is:
feigao 1853kv draw=74A
turnigy 100A esc
2x8.4v 4200mah nimhs in parallel (claimed 40A/batt therfore 80A)

when i guna my throttle from a dead stop the motor jerks and then slowly accelerates.whem i slowly put the throttle on thenm gun it,it accelerates sharply and immedietly.is this because of the lack of amps on startup?or could it be because of the timing setting i have it on which is low?

thanks in advance
