Trampa has conversion spacers, and those bearings exist in 9mm width version.
These ones? I believe those are meant only for their hubs when assembling them. I need them to work with 3d servisas hubs 
Hmm, but if 8 x 28 x 9 bearings exist, I could just use those and ignore the 1mm sticking out

I mean those spacers yes, they probably wont work with 3dservisas stuff no.
These are the bearings I found https://www.twenty4bearings.nl/638-2z-zen.html

ZZ or 2Z bearings will roll more freely than 2RS bearings but not last as long.
RS bearings like Bones Reds (608-RS) only have the rubber seal on one side and, when used in pairs, with the unsealed sides together, can be the best of both worlds.

This one should do the job for example, https://www.boardbumpersshop.com/product-page/trampa-superstar-hub-bearing-adapter-set I think
Edit: there is also one from Trampa and the quality is somewhat better. However, I could not find that one quickly. Both do the job.

Those thinner wires on the motor side are likely covered in epoxy, it’s an easy thing to overlook. Sand the whole exposed wire part with sandpaper before trying to solder it again, you should have an easier time. Oh and make sure to use flux.

I just mounted a peli case with the same method to a mountain board just recently
not to be argumentative, but in the interest of correctness…
the discussion was based on Unity HW and VESC FW…

Fair enough. Don’t use Unity, so I didn’t know. Great clarification

Once I am finished can I just use copy and paste to publish or do you proceed?
Yes, that’s what I do. Edit the post, copy the source, and paste it in a new post.

Is there any disadvantage to using larger motor pulleys? Like, 20T for example.
Cheapest potential option when upgrading to lower kv it seems 
Other than the consequent reduction in gear ratio, not really.
They’re mostly advantages, such as
- more teeth engaged
- less belt wear/fatigue
- less belt tension required
- less belt related frictional losses

The only disadvantage to running a lower Kv motor and a bigger motor pulley would be less effective unsensored operation and more reliance on HFI or sensors, or bigger hip-flicks.
A higher Kv motor with a smaller pulley (to acheive the same speeds) would give better unsensored operation but have slightly more belt wear and frictional losses as @MysticalDork noted

Serious tho. Antarctica is not far away 
Can’t find any location settings… Halp!

Soo, my only real disadvantage is under 2000erpm where i set my vesc to stop reading hall sensors? (Potentially even lower if motor handles tests well)
I understand that 2000erpm at different gearing ratios will mean different speeds but it should be negligible
Anyone tried 12s with the dual FSESC 4.20+? I would like to hear experiences.
I heard of people trying it on their eMTB builds and they failed miserably and some on some higher powered street boards, but it’s just gonna be on a 12s3p Tayto with a 15/40T ratio.
I’m gonna be doing testing this weekend, but would like to know if I should have a medic on call
