Noob question thread! 2020_Summer

I’m talking about the H/M/L settings that some remotes have, like on the VX1 or Uni1.

They aren’t changing the speed, at least not directly, as you mentioned, they are often remapping the throttle min and max calibration to smaller values. Which is not the same as a reduced speed mode.

Ah so it is just throttle calibration remapping? Interesting, gives me an idea.

No. it leaves throttle calibration exactly as is. H/M/L settings and most other speed modes throttle the current applied. Usually medium is about 60% of max current and low is about 40%

What’s the largest production model deck youve heard of? Im trying to find a good sized work tub for stripping them down.

How does that work on a PPM remote though? I assumed that any change could only be made at the remote level because there’s no real communication to and from the ESC aside from the position pulse.

My guess would be a Hamboard classic. They’re surfboard trainers, and as such are 74" long and 15" wide with a wheelbase of 50".

Thanks, I hate it. I’m thinking 15x60x6 inches should be good. Just need something to soak decks in vinegar in lmao

I have a vesc 4 laying around and i want to use it in a ebike but don’t really know how to wire up the display. My bike display has 5 wire.

Were should I start?

Start by telling us what model number the display is or giving us a link to it

Are most Motors (with hal-sensor cables), remotes/receivers compatible with programmable escs like the
Go-FOC SV6 or focboxes and can they be configured to display things like speed, heat and other sensor data on the remote? Or are the escs programmable to use a certain communication protocol/-standard to make them compatible with that bldc software (if that is what is being used for them)
And does the mini remote have no display? (the website selling it doesnt specify that but it looks like a rectangualr hole as for digital displays) speaking about the miniremote from torqueboard :thinking:

yes

most of the time yes, as long they r programmed to access data via uart

mini has no display


im too dum to know about the other question

He doesn’t know what he’s talking about. Speed modes on a standard PPM remote just limit the throttle signal to some percentage of maximum. Doesn’t limit top speed, only acceleration (less throttle signal = less motor current = less torque = less acceleration). As long as your top speed cruising current is below whatever the new max throttle signal commands, you will still eventually reach the same top speed.

Does loctite eventually just like expire? I just removed 4 small bolts from these boosted motors(which are probably rather old) and they clearly have red loctite on them but they screwed right out like it wasn’t there at all.

It shouldnt, but that obviously doesn’t mean everything. They may have also been using the preapplied stuff (you can buy screws with loctite already on them, kind of a paste), which I don’t trust as much as the liquid.

Also possible those screws had already been removed at some point in the past and not had fresh loctite reapplied after that.

Whew thanks I had just never encountered that and it made me distrust everything I own lol

or maybe they have used offbrand stuff, who knows

My brain: old techs loctite no work=time limit?

All I know is that I’ve used loctite on quite a few things, and never had it quit holding when I didn’t want it to.
