to make sure you are set on 4s cutoff plug the battery with the switch in off position and you will get the 4 beeps..thats are how all yaks came from factory since they are madse to run on 4s.
Thanks! I programmed the ESC, and it seems to be working fine with the 3s battery. I have the following setup: 13 x 4 APC prop - 3300 3s 40c - 60 amp eflite esc - stock motor. I got the following numbers with it: 39 amps and 476 watts.
