[@baymoe1]

Nice! Waiting on ours to arrive from kunray

[@TackleThat]

Awe yeah! good choice!

[@dcktater7847]

Some hard data would be nice. Weight KV dimensions for instance

[@TackleThat]

Great point! I should do that more.. for now all the info is on its listing! www.alibaba.com/product-detail/KR5V-Kunray-72V-5000W-Upgrade-Motor_1601074663671.html?spm=a2700.galleryofferlist.normal_offer.d_title.5fdb4340pZuAsI

[@dcktater7847]

@@TackleThat yea i already figured the weight. But the KV is still missing. (Also it'd be nice to see the stator diameter and magnet height.)

[@MooseRidez]

Letssss goooo.

[@TackleThat]

Right?! 👍👍👍

[@strainfly7372]

Hello! Would the kunray kr5v bolt directly to a mx500/650 frame? Or will i need to weld brackets

[@TackleThat]

Oh yeah!! They bolt right onto the razors, no mods needed!

[@ilkzode1822]

Spoke to seller thru aliexpress. Its doubld d shaft only. The rep said i couldnt get or there was no splined option. Picture on their page is a little misleading

[@TackleThat]

Thanks for sharing!! I hope my double d will hold up at 190a, we will see!💪

[@olingerscreations]

How’s the motor shaft? I’ve seen two different types. One that’s like the my1020 and the other is splined like the “one” ec4p. Be nice if it was splined pushing 15+kW

[@TackleThat]

I didn't get to pick from Alibaba, but I got the double D shipped to me. So far so good running 190a (15k watts). I too would have rather had the splined shaft, maybe next build!

[@diy-bj2ed]

Do you think this motor is capable of pulling a lightweight motorcycle chassis?

[@TackleThat]

Yeah for sure, thats essentially what a built out Razor is. Prob be fine for 125cc or less frames. Now if you are wanting to run hard and long, id go for a qs motor.

[@diy-bj2ed]

@TackleThat ok thanks. I'm interested in trying a build, but dont wanna see out the fisrt try works out.. want a qs build but maybe on the second build

[@ChiLly___]

do you have the link where you got it from? the kr5v and how long did it take?

[@TackleThat]

I think they ship pretty quick, like a week or 2 now that they are in stock... but I did wait about 6w for mine since I guess I bought on the pre-sale list. www.alibaba.com/product-detail/KR5V-Kunray-72V-5000W-Upgrade-Motor_1601074663671.html?spm=a2700.galleryofferlist.normal_offer.d_title.5fdb4340pZuAsI

@@TackleThat alright thank you

[@ChiLly___]

@@TackleThat and what would be the best car driver controller for this motor if i run a 72v battery

[@TackleThat]

@@ChiLly___ at least a 72450, you could go bigger if you wanted.. depends on your battery.

[@ChiLly___]

@@TackleThat imma run a 33ah 72v amorge battery

[@FPVirruZ]

How long would it take to ship if i was to order?

[@TackleThat]

Now that they have them in stock, I got mine in a week, air mailed from China.
