Pono,

That looks serious! How much weight do you estimate it will it add, when all's said and done? Any thoughts about going with a folding prop for smoother "touch and go's".

The drive weighs 4 pounds. Controller and battery is an open question. If I just want to go for the lightest weight and assume I'm going to do just a few boosts I could keep it all down to maybe 3-5 more pounds, otherwise 10-15 pounds more. For a folding prop to be worthwhile I'd need to delete the shroud. So no. I can duplicate some of the effects in software by setting an idle RPM.

Hi Jonathon, yeah, that would almost certainly have enough to boost you up. it's a lot more than you'd get with a paddle. And yes, that's probably enough battery for your application. The 4125 is 400 watts, by my estimation, that's about 4 to 6X what you might possibly generate with a paddle. With a 261 wh battery and intermittent use you'd get a couple of hours out of it.

My version is absolute overkill, I'm just using something I already have. I think the guy who built these, Jake Barnhill, is in Australia. You might want to get in touch with him. In his video he hits 46km/h using this drive. Like I said--absolute overkill, I'll probably never use more than a finger brush on the throttle. https://foil.zone/t/complete-geared-motors/11512
