Can anyone suggest what size motors to go with for a twin set-up. I am currently running a TP 5670 720 kv 5y on 12s. I have the flier model 400a 90v red waterproof esc. I would like to go with two motors and use one esc so I need to keep my amps right at 400 for both motors. This esc is supposed to have a 500a max rating, Is there any way to accomplish this for that hull? I would like to still use 12s, so 1 6s pack per motor.
Thanks,

Glen
