Archived: the OG noob question thread! 😀

@Venom121212 and @Flasher do all three of you think FOC or BLDC would be the ideal setup mode?

Should the “Motor Current Brake Max” be the exact opposite of the Motor Current Max?

For example,

22.5 / -22.5 per side?

This is a really good question, Ive always set it to 1/2 of the motor max. Your batt min shouldnt be that high though. Try -6a for batt min and increase (in the negative direction) the number if you want more brakes. Other direction for less brakes.

I set my brakes lower as @Sn4Pz suggested. Makes for smoother braking. Definitely test out the brakes in a safe location first haha.

Agreed, theres nothing worse than drifting accidentally after your first real acceleration :joy:

For sure. The smoother the better. I was trying before to smooth out the brakes with the throttle curve mapping. Specifically using the throttle expo braking set to -100% on each side of the Vesc and I still wasn’t happy with the braking. To be fair, I was using the VESC tool and the new setup wizards for the motors.


These are my settings for an idea

I’ve always been miserably awful at math stuff, figuring all of this out has been tough, only made easier by these forums. I still don’t feel like I have any real grasp of it though. Like these specific settings seem so unique to multiple options of what battery configuration, cell type, motor type, Vesc type, etc idk how to keep it all straight or find real answers without asking you guys

this is the setup window I’ve got using the Ackmaniac ESC tool, recommended previously over the VESC tool. I guess the VESC tool has become fairly unreliable?

I can’t comment on the vesc tool, it been too long since I’ve used it

I can reccomend ackmanicaks fw tho, worked well for the two boards I had it on

With these settings, I’d still be splitting per side right?

Motor Current Max 40A
Motor Current Max Brake -20A

Battery Current Max ?
Battery Current Max Regen ?

I believe 60/-60 was good (if your esc can handle it)
But

As for batt min try something in between -6 and -12 and give that a shot

Before I destroy your build, I’ll do the smart thing and ask @mmaner to chime in

The 60/-60 was just what the tool reading the default config for the VESC I think. I also can’t seem to find the battery minimum you guys have been talking about…

@mmaner help a n00b out? :slight_smile:

What ESC do you have? Have you upgraded to the Ack firmware?

This is where I usually start, but it is dependent on what amps your ESC can handle.

@mmaner I’ll answer for him since you’re already here and hes not :rofl:
He’s using a flipsky dual 4.20
And yes on ack

Ok, with a FS Dual 4.20 set 60 to 50 on Motor max & min and bat max. You can move motor max & min up later if you want more speed.

So motmax60/motmin-60/battmax?/battmin-?
Maybe 60/-60/40/-12

This is what I would do.

Motor Max: 50
Motor Min: -50
Bat Max: 50
Battery Min: -12
