Ah right good catch!

Maybe these SAT SYSTEM™ Precision Truck – REVSKATEBOARD

Does anyone know if it’s safe to unplug all the phase wires from one side of a vesc for efficiency or a broken belt?

I thought I could set current on that side to 0A or 1A but the vesc wouldn’t allow it. I don’t think allowing high rpm and overriding duty cycle limits would have been good for 63100s @ 11k rpm.

When I was miles from home with a broken belt I came up with

wrapping the whole belt around the pulley so it jammed into the idler and wedging the end into the motor mount brace for extra strength.


I know it’s awful but I am typing this from my house

How much does rider weight affect battery usage? I’m building a board intended for someone to ride with me. I weigh 185 lbs, while they weigh more like 140 lbs. I’ll probably use the throttle a bit more than them, too. My board is 18s4p, but I’m planning on going 12s for theirs. I’m having a hard time deciding between 4p and 5p. I know they’ll use less, but I’m not sure if 4p will end up being so much less that they get way less range than me.

I’d be afraid to unless I had a way to cover them. I’ve not done it, but I think you’ll be fine if they don’t touch anything. If they short I’m pretty sure that will almost 100% instantly blow the ESC. Someone on here can probably tell you an easy setting to just disable one side, but I’m not sure off hand.

Just take the belt off. The motor spinning won’t hurt anything and it uses very little power without a load on it. The sound will be disorientating and annoying but it works just fine. You’re likely to get some torquesteer with just one motor on wide hangers.

This is fine if you’re not in high voltage, free spinning at high voltage is scawy.

Scary sounds but you just have to ignore the noises.

I tried that but when one motor spun very fast the other stopped trying. My first guess was I accidentally turned on traction control but it was off, so it must be duty cycle current limits affecting both from just one hitting high rpm. 170kv 16s is a bit high, probably fine for reachers but these get hot and shaky at full 11k rpm.

Should I have re-ran motor detection and set it to something other than esk8 that does cap duty cycle?

I have the receiving side of the bullet connector on the vesc so they won’t short to anything but I would be worried about the vesc trying to put current with nothing there.

For me it works fine, do you have the no limits firmware?

When i don’t want one side to work, i also set to zero the watts limit

Are you sure you didn’t just let off the throttle because it sounded top speed? You have to push it more, the other one will go. Ignore the motor at full speed, it’s using hardly any power and just making annoying sounds. It’s disorientating.

That’s another way to do it. I have the spintend no limits firmware but I think that relates to maximum limits not minimum. I checked minimum motor current and it was 0.25A.

Yes I am sure. I couldn’t even get it to go without me on it. It’s not something that we need to figure out though, I think the power limit will probably work.

Yeah freespinning did not work for me either. My method was canbus.

With ubox you can either use the remote if you have the spinted or uni, or power button method (click it 7 times). Orange light confirms internal canbus is disconnected. Then redo motor detection for the motor you want. There might be another way in vesc tool also i think turning pairing off works for other vesc types.

Unfortunately I don’t think my Ubox has that feature, it has a physical switch for canbus instead.

I’m brand new here, but I’ve owned a Lycaon Swift for a few years. I recently had to replace the battery, but now there’s a loud knocking sound coming from my hub, which I assume is a loose magnet. I’d like to buy a new hub, but I can’t seem to find one for sale that matches my specs since they went out of business. I have also tried getting access to the magnets, as to maybe reglue them or something, but the hub isn’t fitted with screws or anything, and I can’t seem to get it open. Would anyone have an idea what to do here?

If it got put together, it can be taken apart! You probably can’t post pics yet because you’re new. Can you post them on imgur and send the link?

My general question is how on earth do people manage 1wd boards?

This rolling burnout wasn’t on the hill, this was trying to build up speed before the hill with my weight as far back as I could have it.

1WD doesn’t work in the wet unless you are @b264 :sweat_smile:

Doesn’t work in the dry either it seems, I know undriven wheels were wet but that was just after a puddle and the road and driven wheel were dry, at least after 2 seconds into the sliding around.

I think higher psi in the front would make a noticeable difference. I had to get off and push it up a hill :joy:
