Perfect new Flipsky waterproof motor 7070 for foildrive assist?

This motor seems perfect for foil drive assist, what do you think ?


I don’t think it will work. Inrunner in that size will most likely not provide enough torque and thrust.

The 6374 outrunner for foildrive has both a torque and cooling advantage

the data sheet seems to announce same torque as a 6374 motor , the max power seems similar, I don’t see why it couldn’t work, (except if you think the data sheet is wrong) ?

I find the price and data sheet very interesting, especially if you dont know how to waterproof a 6374 or 6384 motor.

Regarding cooling, do you really think it could be a problem ? (my 65161 innrunner motor does nt have any cooling issue)

Thing is that i don’t believe the specs. There is likely the same steel, same magnets, same wire in these motors so it will be difficult to find any magic that provides the needed difference between inrunner and outrunner.

On the theoretic side: Same torque is produced by the same current when fed to the same kV motor but this is dependent on that the motor doesn’t saturate or overheat before you get there and there is a huge difference in cooling between outrunners and inrunners. I wouldn’t take a gamble on this motor.

You obviously can’t compare this to a 65161 which is more than twice the motor steel, wire and magnets

very clear :slight_smile:

maybe I will try it and make a feedback

Doesn’t even look like an inrunner. This might be a potted outrunner. 12N/14P inrunner at that price and size ?
Look at the overall shell, it’s built like an outrunner. I have doubts…

Looks more like an outrunner I agree.

But since it’s called an inrunner…? I guess anything is possible but flipsky should at least get that right.

You’re probably right, amazing description by flipsky😄
There doesn’t seem to be any bearing on the shaft side so outrunner it is. Too bad it’s got a lot higher phase resistance when waterproofed😂 they really should start putting more effort into their so called specs

And looking at the motor diagram it’s a faked one, just some lines drawn on a sheet but not reality

Could work but I´m really in doubt if I should build myself or buy this new perfectly fitting all in one solution…for 3000$ with battery

with only 150WH, you won’t do anything, maybe 5 or 7 waves, you really need more battery and more power for a good foil drive assist. You can build one for less than 1000 €, with a a bigger battery and more power, with almost no expertise, (if you buy a lipo , or a li-ion custom made), and a motor already waterproofed like the flipsky.

It is actually $4500, and additional battery $1200

Actually they demoed it already and it showed an endurance of continious 15min foiltime with 80kg rider and effecient wing… Allthough it is not designed for continious efoiling that is quite impressive for such a small battery system! And it will be 3399€ …see

Indeed the price is better than on their website. If excluding VAT, it comes to 2900EUR…
