Hi all, continuing on quest to build cheap e-board (aim is to plane, not fly), just decided to buy a deep tuttle => naish adapter and found an $80 40cm mast. My next step is to pick a motor and 3D print an enclosure for it. Initially hoping to do direct drive, I couldn’t find a good <$300 waterproof option. But I did find this one with a watercooling jacket for $120, the only problem being that it’s at 600KV. 1: has anyone tried using this motor?
Folks in these parts are using 5:1 reducers on such motors, but is this actually needed? What if I just keep the KVs, but use a smaller prop? I did a test run using an RC “boat” I just built, and it managed to get a SUP with human up to speed. The motor there is a HobbyKing 2040SL, which is rated at 4800KV, running at 220W off a 3S. It did stop in the process (not sure why), but just for fun here’s a video of this.
