that motor draws 52a max. you'll need a 55a esc. some people have been running the scorpion 6 with the align 35a esc with good results. i wouldnt take that chance however as the esc is way underpowered for that motor. i have the scorpion 6 and run that with scorpion 55a esc , hobbywing ubec. also make sure you fly with lipos with a 25c or above rated. anything below that will get hot.
