JK. Damn this is impressive. Honestly shocking what Lipos and RC car controllers are capable of.
Have you tried these launches with the 20s lil foccer board yet?

Too bad it takes away a ton of usability and smoothness. It really makes those ESCs extremely unpleasant to ride with.
But God damn are those RC car ESCs freaking powerful and fess is one hell of a rider for sure

Curious to know what it is about them you’re not a fan of.

Duty cycle control.
Picking your speed is not great when not racing.
Picking your torque/power/current just feels better imo
Throttle as smooth as vesc is hard to do while also having lots of power. And why would you need a smooth throttle on an RC car?
not in a while. had some issues.
been slowly working back to it.
i had the board with me on drag day, but I wasn’t willing to push it yet. wish I was near @hoytskate and their dyno.

As Jackson says just his opinions.
I’m now riding a powerful castle based board, and a powerful vesc based board. I set them both up with the same remote.
The vesc based board is IMO more awkward for handling the power. it’s got less fidelity (mushy and runs on) I suspect it’s the more indirect current control relative to dutycyle control because of the pid loop. but that could be tuned so jury’s still out.
On the street. the castle based board feels awesome. I’m never thinking that it’s “not smooth” or having trouble setting my speed.
They are definitely different. I’m taking the time to get a feel for both now. Otherwise, there’s a familiarity bias there. riders just hate what they aren’t used to. others just have an axe to grind.
The real feature to miss from vesc on RC stuff is voltage and temperature based current ramping as a signal to the rider that it’s time to save the hardware. RC stuff your choice is avoid killing the hardware on your own or enable cutouts and kill the rider. (though hobbywing may have some of that? )
The second is the telemetry ecosystem.

There’s a reason 99% of boards people ride don’t have that jerky ass throttle. It’s not fun imo, just necessary to get those watts.
You are the only person I’ve spoken to that runs RC Car ESCs that says they enjoy it on the street. Even the world’s fastest esk8 racer cant stand RC car ESCs for street riding.
What are you referring to? What input settings do you run? Have you tried all ramping time set to zero?

Of the couple of stooge boards I’ve ridden, I thought the the throttle was mushy, the brakes were gross, and the response was severely lacking, compared to vesc based counterparts.
I’ve never ridden a Castle board at full power but the learning curve is steep it seems.

On the VESC board, are you running default ramp times of 0.400 and 0.200? Bring both of those down to 0.1s if not. Some ESCs get overcurrent faults at 0.0s, but others are fine with it.

@ShutterShock @Shadowfax since this feels slightly off topic for the drag thread. I’ve responded to you here.

familiarity bias factors in here. which is fair. i’m working to factor that out.
appeal to authority, and bandwagon fallacys, in your response.
jerky ass…
skill issue.

The benefits of RC car ESCs for racing must be pretty substantial if those same riders really hate street riding on it that much.
I think that is a far more interesting and important question, is why can’t VESC match the performance of RC car ESCs?
The watts delivered are seemingly comparable with HV vesc setups, so why does Castle/Hobbywing setup absolute smoke our fastest VESC boards in a drag race?
I wish you would learn how to engage in a discussion without personally attacking your friends. It seriously detracts from the fun of talking about skateboards with you.

Which part specifically? Using hummie as an example? I guess could have been said differently.
Expressing my opinion on parts shouldn’t hurt anyone’s feelings unless they’ve associated their sense of self worth with skateboard parts. Certainly a lot less of a personal attack than “skill issue”
This is a thread about draggy results. That’s one of the underlying issues here

I think @Swol_Moon or @Skyart have pulled closer to 16kw on vesc*? I haven’t yet, but i’m trying to get there to make the apt comparison.
other voices in the castle/hobbywing camp. just don’t have the trust for vesc not to blow up and streetface. I think that’s just because of the wide landscape of vescs out there. I see no reason a particular vesc couldn’t be engineered up to the task. i’m hoping to find out the lil’focer is one of them.
*pulled 16kw measured. not rated, sometimes people conflate those two.

The post was just kinda mean man. That’s my 2c. Take it for what it’s worth.
Mean to who though? To castle? To hobbywing?
Is fess an ESC engineer working for them and I had no idea?
If rocinante was constantly breaking down and someone was talking shit about the 100D+ I would not take that personally. It’s a part in my stupid toy
I should also add i’m interested in how much wattage a lighter person would need to get the same accel.
This was rude to Fess, IMO. I’m not gonna put words in your mouth explaining how it came across, but it didn’t come across kindly. Also not exactly kind to hummie, regardless of what his opinion is.

I was thinking that too. I get constsnt wheel slip any time I get over 8kw. I need to try a set of the BRP wheels. My racebox is coming in today so I will have some good testing soon.
