yeah, always calibrate with wheels/pulleys/belts off.

I’ve heard that’s a myth.

Alright, I found the post about thermal paste eliminating the motor chatter/movement but I’m gonna need @torqueboards to help me understand why the motors would be stuttering in sensored FOC (Unity) at 65 amps and beyond. It’s really only happening at sub 5 mph. It’s quite annoying but other than this issue I have been impressed so far.
@Meeep I calibrate with wheels. I would need a video of what you’re referring too (You can send an email). You can try and put some bearing oil on the cir-clip area and bearing area. Typically, that clears up any added sounds that you may hear.

Man , just wanted to say I love these DD, I had to create a profile in vesc app to tone down the acceleration for me.
I recently recovered from a bad fall on another board, so iam taking it easy.
Free rolls like a dream on flat terrain.
Ty @torqueboards for helping me fine tune my issues.

@torqueboards Hi Dexter, on one of my motor, this part is moving:
Is it something I can fix myself ? Does it affect the motor itself ?
Thank you,

That’s just a circlip, so movement is no issue.

Any chance to buy these wheels for TBDD before Christmas?
On your website I see that you can buy the wheels, but I don’t see any type of adapter for the TBDD.

If it’s rattling and bothering you, use a toothpick to put a few small drops of superglue around it

@ThomasL Glue works as @Pedrodemio mentioned. It’s okay if that moves and/or it’s okay if it doesn’t. It’s just meant to keep the bearing from popping out.

Umm, it might seep into the bearing a little. Not that it will make anything stick because of the grease, but it might be a bad idea.
If the c clip is moving n shouldn’t be it’s either grabbing the seal and rotating, unlikely, or the bearing’s race is moving n shouldn’t be. Maybe take the bearing off n glue it down if it’s loose
Yeah, you have to be careful, just the tip of a toothpick, and just on the external side
@torqueboards I never sent in a support email/video but now I don’t think it’s necessary. I thought you’d like to know that the low speed stuttering on sensored FOC was pretty much eliminated when I changed the "Sensored to sensorless transition RPM from 3000 to 5500rpm (max the unity app allows).
I am going to go into the FOCBOX Tool and increase this value more and see if it fixes it entirely. I also vaguely remember @BillGordon saying something about increasing this value on the Elofty direct drives thread.
With this issue narrowed down/fixed, I am thoroughly enjoying these drives. I have wanted a set since the 2018 announcement and ogling at Carvon drives in 2017. Excellent work, you should be proud of what you’ve accomplished! Consider me a happy customer 
EDIT: Changing the transition RPM from 5500 to 10000rpm has eliminated the issue completely.

@torqueboards, I love my new cnc trucks!! Gotta ask why no clear coat though? 
The matte finish was surprising lol but some high gloss enamel fixed that real quick.
It would have looked weird with those shiny new motor mounts

@torqueboards sorry if anyone ask this already but for the Torqueboard direct drive, how long is the DD from axle to axle. I didn’t want to assume that it’s the same as your new CNC trucks.
BTW how long until you put the AT adapter on your site?
@Gee I think it’s about 330mm. Would be same as CNC Trucks. Maybe 1 month for AT Adapters they are in production now

@torqueboards On your site it said axle to axle length is 244mm…So 330 mm or 244mm?
- HANGER LENGTH - 220mm / 8.66"
- AXLE LENGTH - 25mm Axle Length + 12mm Shoulder Length + 11mm Threaded Axle = 49mm / 1.92"
- AXLE TO AXLE LENGTH - 244mm / 9.60"

@Gee 330mm is with 110mm wheels from end to end. That axle to axle length is actually wrong. It would be 318mm. Thanks for catching that.

What motor amps is everyone else using on these?
I’ve tried pushing my 90kv set up to 100 motor amps per motor and noticed some cogging under full throttle, I guess the stator is being saturated. I never had this kind of cogging under full load at 80A, might give 90A a try.
