i did that but velcro is not strong enough by itself it is useful for keeping cables down though and holding the vesc in place

Hey guys,
I am trying to set up a VESC for the first time using the VESC-tool. However I am having issues updating the firmware. When i plug the vesc in i get a prompt telling me to update the firmware. When I go to update it the update starts and after 10 secounds i get a promt saying “Erase timed out”. I can’t seem to figure out whats wrong. I have a maytech v4.12

anyone know hobbyking mount centre to centre distance?

Newest Vesc tool? I had the same issues, and went back to the safety of 0.83 immediately.

You can find it or newer versions here:

Precompiled VESC Tool Archive

Since each build of the VESC Tool is compatible with only a few particular versions of the VESC Firmware, every now and then we find ourselves searching around for a place to download a precompiled executable of one of the older versions. When faced with this situation you either have to find it by googling, ask around on the forum, or download the source code and compile it yourself. All of these take time and can turn a simple task into a real pain. To remedy this, we have decided to crowdsou…

wondering how much range i can expect from a 12s5p 30q with 6x2 aliexpress wheels

i need 30miles around and have a cutoff at 34v

do you think i can make it on a relatively new pack

[PixelatedPolyeurthan]

if you were to do 15Wh/km you could get 43km ish of range. probably more if you have flat roads and don’t weight much (less than 62kg)
to acheive 30miles you would need 13wh/km average on the calc.

[Halbj613]

@PixelatedPolyeurthan

62kg)

weigh less and currently doing 26wh to the mile with half flat wheels

what do you think if i pump them up and ride cleverly

[PixelatedPolyeurthan]

@Halbj613

26wh to the mile

what’s that in Wh/km lol?
i don’t know how to make the conversion… well i think i do lol hang on

[PixelatedPolyeurthan]

@Halbj613

26wh to the mile

so you currently do 41wh/km?? you’ll not have a chance if my caluculation is right

[Halbj613]

no do 16wh per km

[PixelatedPolyeurthan]

oh lmao i multiplied
yeah you should be able to do that

[xsynatic]

I get 12-17Wh/km and reach 20-27km with a 12s1p lipo. Cutoff at 42/40v. And i weigh double as much.

10s4p 30q gets me around 20ish km. (although i ride fairly agressively)

[Manola1027]

Awesome i’ll try that! Thanks

[Halbj613]

so you think i should be good its around 50km

[xsynatic]

Probably. Pump your tires up more, don’t race the cars and you are proooobably fine.

[Manola1027]

It works now! Thank you so much:D

what are the pros/cons of 2 x single esc’s over a dual? been looking at the neobox dual or 2 neobox v6’s, price suggests just 2 v6’s, but maybe im missing the benefits of a dual system…

[wandagoner]

fair question and everyone has their own opinion and here is mine, i’m ignoring cost as that can fluctuate.

2x single
Pros: if an issue arises in one you are able to pivot to single motor temporarily.
Cons: potential for single point of failure, sometimes a larger footprint than dual

1x dual
Pro: smaller foot print, some have integrated components like anti-spark
Con: potential for single point of failure.

[Geo_Engineering_FTW]

sorry if ultra-noob question, but what is a ‘single point of failure’? like what would be an example?

[Venom121212]

Any 1 part of your project that stops you in your tracks if it fails.

So if you have a dual motor build and one motor dies, you can still limp home fine with one motor.

A single motor build will be useless if the motor dies.

In the single motor case, the motor would be a single point of failure.

If you cut a wire into 6 pieces and solder them all together to make a wire again, you have created 5 more points of failure.
