How do I order these ?
ok so just so I got this right⌠grub screw on the inner collar, (im gonna file a small flat in the axle to be sure) and loctite on the sleeve nut and Iâm ready to roll?
these things will handle 12S alright yeah?
I donât have a 12s battery so I canât test this but they work fine on 10s, 12s wonât improve on efficiency much unless reducing the kv more to get a higher voltage at your desired speed.
The motor are 70kv +/- 5kv so your top speed will be 50km/h on 12s but the motor will only be spinning 3,100rpm or 43,400erpm
These are my recommended setting for the hub motors.
The braking is not to strong but very sudden if you use the default motor setting and this is not what we wonât for motorised longboard. The settings I have set are very smooth and progressive braking and I feel you could increase the setting to tailor your own riding style, but at this point do not increase max current over 40a and I have not fully tested it.
As for BLDC settings: The BEMF coupling is working best at 300 The integrator limit 150 Min ERPM 50 Int limit min ERPM 600 Start up boost 0.09
When doing motor detections these where the readings I got but then all of a sudden I started getting a BEMF reading of 2000 this could be vesc related but if your motors donât work with your own motor detection or if you feel it looks a little high the set it at 300.
Benjamin Vedder suggested setting low duty to 0.9 for motor detection for these motors and this might fix the problem.
The rest is just setting for the space cell.
This is data from only 1 vesc out of 2!
Ok guys first i have to apologise for the sound i forgot to get the sound to record form my web can that i was holding instead of my macbook mic that had road vibration and the carbon fibre lid the wasnât fully shut to let the usb cable out.
So the first hill was a 10deg hill that i have gone up in a few of my videos, the second was the 28deg hill i went up in my last video, this time i made it 90% of the way before the battery amp cut off went on my second vesc you can see that the first got to 22a and the limit was 25a per vesc.
as you can see the video feed cut at the last second because my board started rolling back down the hill and my web cam usb was in my hand.
I have set up the settings as you have described, but when I ran motor detection it came up with slightly different parameters is this ok?
also my first test spin sees them cogging a bit at low speed, but I havenât finished my 12S yet so I was testing with a 6S I assume this probably has something to do with it and it will probably not be an issue on 12S.
Can you screen shot them for me, you have about 3 strands of copper more per phase then me so being a little out is fine,
More cogging at start up is to be expected with hub motors because they have a lower rolling resistance then a belt drive, so it takes the vesc a little longer to get to the biting point, but jump into the advanced settings at set the start up boost to 0.06-0.09 is what I have been playing with.
i forgot to also change rpm settings that where suggested by vedder, these have also bee suggested for the carbon motors on this thread http://www.electric-skateboard.builders/t/vesc-faq-best-settings-for-hub-motors/212
As for BLDC settings: The BEMF coupling is working best at 300 The integrator limit 150 Min ERPM 50 Int limit min ERPM 600 Start up boost 0.09
Very impressed with the overall quality! I have yet to mount the motors to trucks just some bench testing. Im hoping I can finish my deck soon to try these bad ass mother f@#%ers out. Should be done by april. As you can see Iâll be using 2 VESC and a space cell.
Only issue so far is I seam to be missing the large axle screw on one of the motors. Im not sure if I misplaced it or if it never shipped. Either way I will need a new one so @jacobbloy just let me know the cost and I will paypall the amount.

Just out of curiosity, what is everyone using as the front two wheels with the orange 85mm hubs. I bought Jacobs and Hummies hubs, the black 83mm are no problem to find but cant find the orange in the US only in the UK under 60.00.
I am all most positive they are the orangatang kegel
What Iâm pouring is the same dimensions as the kegel. 80x56
Thanks for the info.
I just received my 83mm flywheel clones, and they are a pretty close match for diameter. however I neglected to realize that I will need to put 150mm hangers on the hub motors to even out the offset. VESCâs in sync and ready for a test ride.

What size hanger do u have on the front?
Yes there is a 30mm offset! Depending on the riding style I have had no problem with the offset effecting my ride! But I would suggest a 150mm hanger for the back, Paris does a 180mm and 150mm hanger.
they are 180mm hangers. should be fine for testing. but for the final product I might change trucks all together.
Still waiting on mine.
Well this is unfortunate 
I dont think I put enough loctite onand I spun the axle and broke at least 1 phase wire.
You need to put lock tight on the nut and on the grub screw, also a flat spot on the axel can help!
But yes this is bad, if you donât think you can fix it I will replace the motor!
