Crawling without a drag brake

You Dudes. I'm thinking about trying my sensored brushless castle 1410 3800kv motor in my sport. I dont have a good crawler sensored esc but i do have a traxxas vxl3s laying around which does have a sensor port but no programming capabilities.

Have any of you tried crawling without a drag brake? This is probably a bad idea but i thought id ask anyway.

It's a bad idea. Definitely need it or you'll lose it going down. You'll burn the motor trying to keep reverse to climb down.

What about... and hear me out here...installing a dig on the 3rd channel and therefore having actual brakes instead of drag brakes.

It'll have brakes, just like a slash would. Would just have to hit the brakes often. Probably would be tricky and get frustrating, but I suppose possible.

If you're after a cheap sensored esc with crawler capabilities (100% drag brake, instant forward/reverse) the hobbywing 10bl120 ain't bad for the price. I use one in my son's crawler, been dependable.

That's only the AXE models from Hobbywing, those are proprietary tech (mostly because of the connectors).

That won’t work in the TRX-4 in sensored mode. I bought one, couldn’t reverse motor rotation in sensored by programming so I had to upgrade to a MAMBA X

I think you reverse a sensored motor by switching any 2 wires.

That’s only for sensorless. If running sensored it has to be A B C to A B C
