Steering Trim Qusetions...

[NZ Offroad]

I just got my 1/8 Rockslide SuperCrawler the other day.
I am a tad confused as to the steering trim adjustments, that
are somewhat explained in the manual.
It says " This dial is to centre the rear wheels. The range is around
0 - 100% on the left or right rear wheel "

So is 50 % the technical centre??

It sounds like the adjustment can be made to each wheel.

What am I missing here???

Thanks guys

Ideally, center the steering trim on the TX.
Remove the servo arm/horn from the servo.
Power up the rig, this lets the servo center to the radio.
As best as you can, install the servo arm/horn on the servo keeping the wheel straight ahead. Install servo arm/horn screws and/or tighten clamp.

Now, use the steering trim to make the steering centering perfect, you may want to drive the rig forward with no steering input to check.
After that is done, check the steering EPA's, the radio should stop sending a steering signal just before the steering linkage hits hard parts.

I doubt you can change a single wheel centering except via a linkage change/adjustment. But I don't know the rig.

I don't know if yours is like mine but there is one dial trim to center the steering, and then there is a second one from 0-100% and what that does is it is technically a limiter, (100% being full steering capability and zero being no steering.) Just a little bit, sorry if I just made it more confusing Oh and it is and exceed controller,

[NZ Offroad]

Thanks guys.

No confusion, how ever I do notice the rear wheels turn the same direction, as the trim is adjusted, therefore ruling out crawlerbeast's excellent theory that it could be servo-throw %. I can set that from the control too. I'm still now lost, however, as to the 'technical' centre, without having to take it apart, as mentioned by Charlie-III.
I'd only take it apart if I know what the 0 - 100% actually does, and where the mechanical centre if that range is.

Not too sure if I'm confusing anyone. So here's a link to the crawlers manual.
I've just noticed the online manual differs to my hard copy. Online manual says 0 - 10% ..... but the transmitter allows 0 - 100%

Redcat Rockslide Manual

Cheers guys

I think it's just a simple trim, nothing special. It's hard to tell for sure, it could be (as you sorta mentioned) it may be a "dual rate" control.

I predict you will change out the motor bullets soon as well as the Tamiya pack/ESC connectors.
Both WILL give you problems down the road.

[NZ Offroad]

Thanks, yeah trim is a trim i guess. The 100% thing got me stumped. So in saying that, would 50% be "centered" ??? And as it's moved toward 0 or 100, the trim turn will left or right??

I would say so. Why not just try it out & see??

[NZ Offroad]

Oh yeah, real funny fella. How about not mocking me ???
I joined this forum as I know f all about crawlers.
If that's the reaction I'm gonna get from a person with 5575 posts, I'm better off not being on here.
Your post was fine until the laughing heads pissing themselves at me.
I wouldn't ask the question if I knew the answer.

[Solitaire]

An honest question, really. Why not try it and see how straight it drives. If it drives in a circle, adjust to suit. No need to get irate.

You might try the Redcat section of these forums. Maybe someone there has the same controller.

[NZ Offroad]

I'm not irrate, not one bit.
Just don't appreciate someone knocking and mocking a person who joined this forum to learn.
Not everyone knows everything.
And thanks again for all the help everyone.

WTF? Charlie is like the most mild guy on here so if you get offended by him then you are in for a rude awakening...He is trying to help you dude.

His suggestion is what I would do, turn everything on and mess with the knobs and see what each one does. From there it should be easy to get it to do what you want it to.

[NZ Offroad]

Yes yes people I appreciate the advice.
I don't get what the WTF is for though??
I made it clear I didn't appreciate the laughing heads AFTER his helpful advice.
If that can't be understood, regardless of Charlies' personality, well I
don't know the guy, And I felt the laughing heads were mocking my apparent lack of practical experimentation.
If not, hey I apologise genuinley to him.

[Charlie-III]

NZ, not trying to mock you. I sorta felt it was a reasonable question, possibly so reasonable that it was overlooked.

Yes, the Redcat section may give better answers than we can give.

Have fun with your rig.

What center is on your rig is going to be relative to your steering linkage. It may be 20 to the left or 30 to the right. As CIII said take the servo horn off turn the rig on leave the control at 0. While on; reinstall the servo horn. It needs to be putt back on as close to your rigs steering center (wheels pointing straight ahead). Now drive it some - if it pulls left you need to adjust the trim to get to center I.e do same as if it pulls right. I hope this helps.

[stanmondz]

the trim adjusts the servo to "center" it. gets the wheels pointing strait.
the knob with 0-100% is a dual rate control. that means the % of steering throw the servo gives relative to the steering wheel on the radio.
example
set it at 0% and it wont steer
set it at 50% and the wheels will move 1/2 of what the servo is able to steer them
set it at 100%,you get full steering throw


there is no set in stone setting for your trim control. or dual rate. every truck and radio will be different.

the best way to set your trim is to throw the truck on the ground and drive it, if it pulls on way,turn trim the other way

Really, he gave you good advice on your question. if you cant figure out a simple trim maybe your in the wrong hobby. Charlie has answered many questions on here and most were spot on , I would take his advice anyday. being new here maybe you should start by dropping your attitude.

[NZ Offroad]

Hey crawlhog, had you read further down this thread, you'd maybe have read that I actually apologised to the man.
As for a "simple trim", and "Wrong hobby", as you so mentioned, is this site here to help, or not ?? Not everyone knows everthing,
and entering a new hobby, I thought this site was the ticket.
I know what trim does. It was the 0 - 100 % ( without a centre indicated ) that stumped me.
I didn't come on here to be mocked, so the attitude was justified, until it was made clear to me by CIII that
was not his intent.
So maybe telling someone he can't work out a 'simple trim' is attitude too?? Ya think?
New here, or not, I'll stand up for myself.
You should maybe read my very first post, in the SuperCrawler section.
It outlines the fact I take no crap.
Your signature, "dont get mad get even", is great. So thats what I did. I hit back at an apparent mock.
Hey as far as I'm concerned, I'm over it.

[transambill]

The 0-100% thing that's messing you up I'll try to help on. Don't know about your radio but most have 1-100% L for left and 1-100% R for right. Center of that would be 0 or rite between 1% L and 1% R.
The trim helps to fine tune your front so if you point your wheels strait and you've gotta turn them a hair one way or the other to get the servo horn to slide on, the trim is to help you turn your wheels back that hair so there pointing strait again. The expo controls how much your servo turns in either direction.
Example, at 100% expo you discover your tires hit the lower links at full turn. Your going to want to turn your expo percentage down till the tires almost touch the links and no farther.So turning down the expo decreases how much swing or how much the servo is going to turn your tires in that direction.

[Charlie-III]

Hey NZ, hope you have your answers, let us know what you find out so we can better answer the next guy with the same rig.

Have a nice day.

To those that supported me in this thread, thanks. Also have a nice day.

[NZ Offroad]

Sure do, cheers.

50% is centre. And it runs as if it is un-stoppable.

Cheers CIII, I do now know u were not mocking me, and NHF I hope.

You too have good day, it's winter down here, you guys lucky at moment.
The Arctic chill is unreal during winter.
