Setting up a crawler ESC

[zomboided]

I've just installed a Tekin ESC/motor in my crawler and I've no idea what kind of settings I want to use as this is my first crawler.

I know I need to go out and try it out, but I'd like to start from a reasonable config.

Drag brake - can be set 1 (off) to 11. What's best when trying to climb stuff? Do I want maximum braking so the truck doesn't roll back? If so, what are the down sides of having it this aggressive?

Reverse strength - I'm used to 1/2 speed reverse, does this matter when climbing? Or is it just a preference.

Throttle response - I'm guessing having a shallow to steep curve is better so that you have more control at slow speed? Or is a linear response better?

Finally, push control or anti-drag - what? Why do I need this?

Any hints from those that go crawling would be much appreciated!

You want drag break pretty high to hold it on hills / rock gardens, but how high is up to you - some people like to have a little but of slack left so the rig will move downhill slowly under its own weight.

The Tekin FXR in my SCX-10 is setup like this..

Drag brake to maximum..

Reverse to maximum... (This can be useful if your about to roll when climbing..)

I think that the throttle curve is linear..

Then fine tune from there to suit your driving style..

I agree with those settings ^

My Wraith has a Tekin FX ESC. You need full reverse as you'll likely find yourself having to reverse up a slope at some point even if you're just turning around, you may not be able to do that without full power in reverse. I found that out the hard way when running a TEU104 in my CC01

Max drag brake is useful for holding the car still on any gradient but it will also kill the rolling effect when you come off the power. It can take a while to get use to or you can turn it down to 70-80%.

Brilliant feedback, thank you gentlemen.

Any opinion on the push control / anti-drag. Seems to be counter to the drag brake if I understand it (and I'm not sure I do), so I'm guessing off is the right setting?

And I'm guessing with high/max drag brake, immediate reverse is the way to go, so no reverse brake/wait a second for reverse nonsense

hi,

i found that the drag brake should be just that, 'drag' , the car should roll very slowly down 45 degree or steeper slope at neutral , keep the separate manual brake enabled so you have to use the brake to come to a dead stop , and have a double tap style reverse , the drag brake should act just like the engine braking in a real 1:1 scale 4wd , i cant begin to say how many crawlers i have seen flip over because of instant reverse or too aggressive a drag brake setting , just watch a few youtube vids and you will soon spot the cars with badly set up esc's

its all personal preference of course and trial and error will find your ideal set up ,

have fun

The braking process used by our ESC's is otherwise known as dynamic braking.. Basically for the brakes to work, the motor needs to be turning..

As for the ESC settings, it depends on so many things, such as, but not limited to, vehicle weight, vehicle weight distribution, Motor (both turns, and magnet strength) gear ratio, the driver...

Sorry, I cant help with the Push control/ anti drag, I don't remember seeing it as an option the last time I had the Tekin FXR connected to the Hotwire programmer.. Maybe I'm using a different software version..

May I also suggest enabling the LiPo cutout if you are using LiPo batteries as well...
