Sorry, I forgot there are more than one Habu. This is a Habu 32 motor - 2150kV 32 size. I guess there is a smaller Habu with a 15 size motor 3200kV, that must be the one you mean.
I was going to go 6S and 100A controller, 5 to 5.5" prop
TBD.
Know anything about annular cooling inlets? So far I have this set up with a prop adapter and no spinner, and about a 1/8" clearance all around the adapter, i.e. it is sticking through a hole 1/4" larger in diameter with a rounded lip. While this opening is much larger in area than the 4 cooling holes in the motor, I am concerned how much air I can expect through there.
