just got my controller , servo, reciever and esc in the mail. ive connected my motors both 2 the one esc and connected the esc to both channels and i get no engine response on either one but i get response from the servo on both. there is also a connect seperate from channels callled the BEC. im not sure where the problem is but the esc is a 20/30 amp 9.6v and the motors are 400 graupners.
