Interesting. I guess water flow directly through the stator laminations is the best way to do it.
@Brucecreations solid battery! I’m guessing they’re a Sony high discharge cell? Did the battery handle it ok?
@cim96dm7 that’s not very promising for such an expensive product. What are the specs of your battery?
Anyone know how much power these MHz jet drives use when up on the plane and when accelerating onto the plane? When @cim96dm7 says 200a have you measured this to be the current it is drawing from the battery? I would think that the current levels would be within the VESC 75/300 capabilities.
