2650 motor will draw the amps, with 4s you will have over 38k rpms wich is aprroaching the high limit of what you want
so a 4s will suffice on this setup if I get at least 30c? I just know the setup is power hungry and I don't want to underpower it resulting in fire or whatever it is they do.
oh..I thought they were referring to the 1515, which I was curious about. I read it quickly. If the 1512 is that then I would say the 1515 is quite a bit more. Thanks
