I just setup my VESC with these babies and seem to be hitting 24-25k eRPM with 23 volts (6s) which indicates a kv rating of about 150. Perhaps I did something wrong @chaka?

Are you talking about the 200kv or the 170kv ones?
Sorry same as yours 200kv

Duty cycle is only showing 82%.
I tested these on a calibrated kv tester. I’ll make a video and post it tomorrow.
How did you get it to top out at 82% on that screenshot?
So when controlling from the control panel on BLDC tool (bottom right), I couldn’t get duty to go past 50% for some reason. I only got 82% duty cycle by using my remote.
After I switched the phase wires around, I am now getting higher erpm (with remote)! Though still not as high as 200kv.

The proper way to evaluate the results from realtime data is to divide the power by the motor current to find the actual voltage being delivered to the motor.
In your last screen shot we are seeing the power equaling 15.6W . We divide that by the motor draw of 0.73 amps and we get 21.4V
Now we take the ERPM of 27856 and divide it by 7 pole pairs and get an actual rpm value of 3979 rpm. We can now divide 3929 rpm by 21.4V and we get 185.5kv but we are only running at a duty cycle of 94.4% so we need to calculate for that. We take 185.5kv and divide by 94.4 and we get 1.97 which we now multiply by 100 to find the actual or estimated kv of 197kv.
The actual kv of these motors measures around 203kv with a calibrated instrument. There seems to be a small margin of error when measuring with the realtime data plot on the VESC.

I got a slightly different number for the KV before calculating 94.4% duty cycle, but still landed almost exactly@ 197kv.
15.6W/.73=21.4V
27856ERPM /7=3979RPM
3979/21.4V= 185.9Kv
185.94/94.4= 1.97
1.97*100= 197kv
Sounds perfectly reasonable to me. Totally checks out.

exact same number as mine, nice!

Took the motor out for its first spin last night - it’s a sprightly little thing

Do not try this at home!!! Traveling at speeds above 20-25 mph is extremely risky. Skateboarding is inherently dangerous and can cause serious injury or death even at moderate speeds.
I had a few users wanting to know if they can run the 200kv version at 12s with the VESC V4.12 so I fitted one of my 12s boards with a pair on 16/36 on 90mm abecs. The torque was a little lighter but they still climbed a 10% grade at 20 mph, Might try a steeper hill later today. Top speed was a little over 37mph in a full tuck and the motors were hot but I could still hold them in my hand after the high speed runs.
I still recommend going with the 170kv motors at 12s but the 200kv motors seem to be working fine. These motors perform best if geared to top out at 30mph and under, if you really want a high speed beast you will want to wait for V6.xx VESC and fit them with some 6368 or larger motors. I’ll use this board as my daily driver for a few weeks and make sure no faults develop.

any price estimates for a V6.xx VESC?
Does anyone know of a pair of trucks that will allow you to do a Dual Rear setup?
Once the BOM is made public I will calculate the price. I also need to be sure the enclosure/heat sink fits before I send it of to fab.
@Sboard342 I think the om5065’s will fit on the older 42 degree buck trucks paired with @psychotiller 's r.i.b.a. mounts. I have a set but I need to turn them down on my lathe to get the cups to fit.
Hey, couple quick questions.
-
I am assuming the discount deal is done?
-
is it possible to have 4mm bullet connectors put on?
-
if i buy one tonight, do you have an eta on its arrival? (i’m in MN)
I ship them via priority mail, 2 to 3 days shipping. If you leave a note during checkout I will switch out the connectors for you.

Awesome!
So discount deal is done?
(doesn’t really matter since i already made up my mind 
just wondering)

thanks! Right now I am using the Caliber II trucks. What if I mount one forward and one backwards for now? Any concern with this? Or would I be better off running diagonal?
Yeah, I ran that discount during the first production run for those that pre-ordered.
@Sboard342 You can do the ying yang style of mounting. In my opinion it doesn’t look esthetically pleasing but it works. I am a big advocate of a dual diagonal setup for weight distribution reasons. The rear end will wash out fairly easily in a dual rear and when it does it is hard to bring it back.
My concern in the dual diagonal is wiring up VESCs to battery and canbus connector. I am thinking run battery in middle with VESCs at each end.
