Has anyone tried to open the grill hole in the front of the body, make (3D print, maybe) a nice duct and lead the incoming air to the motor? I know this might require opening the rear a little more to let the air out again, but do you think / know it will work? Requiring no fans, no power taken from the battery? Maybe only a heat sink on the motor?
