Can your remind me, how much does your 4wd board weigh?
wow surprisingly light! I’m watching these motors closely, waiting for the dust to settle a bit.
I’m thinking of running these with the v4 speeddrives. Maybe just once to test.

Had the same tought But i don’t see any interest at the end Wether you go carvon AWD wether you go hummies AWD
4wd 12S6P and only 25lbs? Nice, my 4wd is just under 30. Where do you think your weight savings are coming from?
Sounds like there’s some cool stuff right around the corner!
Wheels? You run some heavy wheels.
Good point, thats probably it.
I don’t think it’s 6p now. I’ve been ridding it. I think he was talking about some possible future board. Don’t know what this weighs

They tell me in five days they’ll send the parts. Always a delay I know but they are a real place and real MOTors wil be made. Soon come hold onto your remotes

ugh and they tell me Thursday they will send now! at least they’ve been showing me pics and things are looking good.
@evoheyax I noticed that the wires on your test board is going underneath the hangers. I assume you are doing this because it is easier to route the wires into the board setup that you have.
Is it possible to route the motor wires above the hangers when using a different deck setup?
12S5P AWD on 16/33 ratio with 107 superflys. Propels a 220 pound man up to 37mph (actually done, not theoretical) while carrying an additional 15-20 pounds of work related crap. board weight: 24 pounds.
we may be bumping this guy’s board up to an 11 ply deck soon however, i’m seeing signs of wear that concerns me for this particular rider. Also he seems to like to crash into things. That weight class is definitely pushing the upper limit for my typical 9 ply decks at the wheelbase that i used here, which is longer than usual.
So lets talk about torque on a 5074 stator or whatever it is you’ve got in there because i’m eagerly watching this and hoping for hubs or direct drives that can actually compete with belt reduction. I’m watching you guys and working with Carvon so i’m obviously not married to belts but so far…

i got one motor to confirm the new design and its all good except one mistake where the bearing housing is too loose for one bearing. I guess this is to be expected and that’s why they only sent me one to confirm things. They say ten days till the rest are done and they’ve always been maybe two weeks behind schedule but we will see I guess.
Talking of torque with a 5074 stator…well it’s 4752 in these motors so not quite that big. I think what’s really worth comparing is the Km, which is the torque output efficiency. So a smaller motor with 100kv will put out as much torque per amp as a 100kv big motor, as defined by their kv, but almost always the bigger motor will be more efficient so it can put out that torque or power for a long time and stay cool, and therefore continue to keep its good efficiency because its cool and get better range. It will have a better Km.
I’ll post up some pics of the new motor later tonight which show how it’s built and that’s the advantage of this newer design.
But besides design and back to talking of km effects this new motor is as big a motor as @evoheyax has been using so seemingly similar, but really since we rushed to get his wound the weight of the copper shows he’s got 100 grams and after figuring the ideal winding I get 120 grams in, which results in him having greater wire resistance at .06ohms than my .05ohms. So put an amp through and you can calculate how much will turn to heat. I have a better Km motor but we have the same kv.

Are you sure about the weight? AWD and superflys, 24 lbs?
it weighs more now because he has this crazy foam topper on it but yeah. 24 and some decimals before it shipped.
hubs just move some of the metal from outside to the inside. I’d like to see a weight comparison of hubs vs motors with mounts bolted onto them.
The fucking raptor 2, a 10S4P with a slim sexy box, weighs just as much as my 12S5P base model scarlets which are rear wheel belt drive at over 3000 watts per motor and are right in the 21-22 pound zone.
They just keep adding steel into those wheels. Looks lighter, but isn’t. They’re getting some real power in there finally, but trading lightweight aluminum outside the wheel for heavy ass steel inside the wheel isn’t going to reduce weight. I doubt that’s really the objective at this point though. Right now they’re still just trying to surpass belts in power-to-the-street and flexibility.
also i’d like to point out that batteries, in the grand scope of the entire board’s weight, aren’t the biggest contributor. Cells don’t weigh much.

That’s crazy lightweight. My 2wd with superflys weighs 25lbs.
Well I tried @evoheyax board at SPD2 and that thing is crazy powerful and the best part is it’s super stealth both in appearance and noise
@Hummie Is the urethane hot-poured or mixed? Since you’re getting the PU done in small batches, I’m curious about how the final product’s PU is casted.
