Had this junk laying around, I have a buddy that’s into Batman... then this happened.

 

Still testing it... needs a little tweaking.

Cool!

That esc is way over kill for this setup.

Id remove the heatsink and heat shrink. Wrap the esc with Kapton tape

David it’s the only switch available. It was intended to handle a multitude of slot car applications.

 

The heat sink and shrink wrap are part of the switch. Removing them could be a bad thing.

the brushless motors make plenty of power.

Tom, I don't mean to be disrespectful, but I have to ask. You're saying your switch did not start off life as an ESC? Sure looks like one.

What is the weight of motor, esc and switch combo?

It did “start “ an ESC Phil.......now it’s a switch. I can’t turn any ESC into a switch,only that certain one.

The motor weighs 7.5 grams....the switch weighs 17.5 with full length wires.

You can shorten the wires and cut 3-5 grams more.

The input wires can also be replaced with thinner gauge. That motor your using is nothing for that esc. You might have converted the controller to a "switch" with programming but its still a 3 phase, Dc, esc. I would also consider removing the large cap and install a smaller one. It takes time to charge and with your use time is not on your side.

I'm setting up 1106 motor with surface esc and tx.
I don't know enough about a switch to make it work.
I expect the setup is going to weigh a couple grams more than a x12 motor. And programming with the esc and adjustment with tx should get me the car working on the track. The cost is about 100$ and according to what I have read, performance is about the same as x12. Definition cheaper than a bp x12 and high tech electronic controller. And I like that I can drive from different parts of the track. There's nothing to wear out on the motor.

Yeah that’s where we were 8 years ago with all the R/C radio stuff and the track owner didn’t like his track hot all the time.

you may find it trips the power supply when you shut of or go over the counters 

with the track on full 12 v ,the back emf pushes up the voltage and trips the PS

i think its going to be undrivable in that chassis

yeh - NSR chassis maybe a little weak LOL. But it will be my test bed to iron things out on my rolling dyno.

also, I'm prepared to dial back voltage to 2s levels at the control panel, and use lesser KV motors.

and planning to use GTP body and a wide track with NSR chassis for track testing, then installation on a proper 1/24 chassis!

 

making my best guess at this, will be a fun development project

Batman is done. The best pass I got out of him was .733 @ 47mph. He hung in there @ .760’s pretty good.
