Good turning radius? (Diameter?)
 

So I'm finishing up my sporty, sucker punch chassis, XR wide mod axles, OD / UD, axial unis (beveled at the corners), hulksta plate, 7950, etc.
What is a good turning circle? Like if I drove in a half circle, what should the inside "door to door" distance be? Or wheel track to wheel track?
Maybe measured on concrete, so we can have similar test conditions, since it seems smaller on loose dirt...

Re: Good turning radius? (Diameter?)
 

Can you post some pics of your setup?
Some numbers that you came up with?
Does your rig, push the front end or pull the rear, when your turning?

Re: Good turning radius? (Diameter?)
 

What steering arms do you have? 50* is all that's going to happen unless you modify VP arms or run something like rcbros arms.

I'll go test mine in a minute but I've got 70* turning OD / UD and a heavy front end that keeps the front planted.

Re: Good turning radius? (Diameter?)
 

Smooth concrete floor 44" outside tire circle. On grippy surfaces it's much tighter, I'd say in the 36" or less range.

Re: Good turning radius? (Diameter?)
 

So I'm getting about 45* of steering, but like a 48" circle, measured inside to inside, on carpet.
The front end is quite heavy.
I don't know how to answer the push or pull question, the front wheels turn 1.2 times (or so) for every 1 turn of the rear wheel.
The angle of this looks kinda off...

It is clocked pretty far, I guess that could be what's holding it back...
I'll go test it on concrete tomorrow

Re: Good turning radius? (Diameter?)
 

Get some rcbros or krazed arms on there and you'll start needing to narrow your links and shock mounts on the axle. :lol:

I'm running ar60's but the concept is the same. My links are I side the stock link mounts and the shocks are angled to clear the tires. They still hit pretty solidly. :lol:

I don't know the degree's, but it looks like this..

36" on the vinal kitchen floor..

If the rear is pushing the front, you have, push.. (bad setup)

If your front is guiding the rear or pulling it into the center of your circle.. you have, pull..

The only problem with this test, is, it's not really what's happening on the rocks. But for thought, it helps ballpark..

Need more info on how it works or acts and reacts, on the rocks.

I would recommend a longer horn and a little less caster.
When you go with more steering, you'll want to mod the inside of the uni ears, as well.

Re: Good turning radius? (Diameter?)
 

Yep, White Trash is right.

Never thought I'd type that....

You're gonna have to pull the arms out front a bit to get the leverage on the servo arm, and keep the right angles on the knuckles. I completely recommend the Krazed carbon arms if you want to keep those knuckles. As far as clocking, looks good to me. I run toe out, and dig that shit into my shocks and links. Helps with the polished look.

Re: Good turning radius? (Diameter?)
 

:lol:


The 8* parts he's using help with turning but not a whole lot on the rocks. I've ran 70* with both scx c hubs and wraith and the scx keep the angles pretty even across the whole range.

I run a few degrees of toe out too. The dlux setup goes slightly toe in on the outside tire at full lock without it.

Re: Good turning radius? (Diameter?)
 

Funny you guys like a little toe out..
I run a little toe in.
The outside tire, is the tire doing the work/steering.
With toe in, you get better, smoother, steering
With a little toe in, it keeps your insides tire from rubbing or possibly binding up your drive train.

Re: Good turning radius? (Diameter?)
 

That technically helps with "wheel push". 8* makes it harder to "push" the wheel towards a different angle. When you come up on an obstacle, and depending on how you approach, 0* will stress the servo more than 8*. The wheels can hit the same angles, regardless of toe/caster/camber to a point.

If you're turning the wheel and the inside turns farther, that's Ackermann.

Re: Good turning radius? (Diameter?)
 

I only run enough to get the full angle on both knuckles. If there is too much toe out it will limit the outside tires ability to go full lock for sure. I don't run that much, once passed about 30* the tires go even to lock.

Exactly. 8* knuckles make a big difference in open front diff rigs and on road, it doesn't help so much in a sporty. The 8* king pin inclination and the same 15* or so caster I ran with both styles of knuckles made the 8* look much more exaggerated so it appeared to turn much sharper than it really did. Plus it put the inside tire into the shocks pretty hard.

Re: Good turning radius? (Diameter?)
 

So how much caster is too much?
My last rig had a ton, and it really seemed to help when I was like walking the front end up with the servo...

Re: Good turning radius? (Diameter?)
 

I'm headed out tomorrow to do a bunch of testing. I brought the toe out back in and made it toe in to see how it reacts. My gut tells me you're right even if my head and (slight) ocd says you're wrong. :lol:

Re: Good turning radius? (Diameter?)
 

Take some tools and post as your testing.
You can dial your rig in, thru the internet now! Lmao

Re: Good turning radius? (Diameter?)
 

I can do that. I changed a bunch of things all at once that needed to be done but I can certainly post about the steering. :mrgreen:

Re: Good turning radius? (Diameter?)
 

With the, desTroy plate, your running, the knuckles aren't going to make up enough stress, to hinder your servo.
Not anywhere as close to the stress your servo took, before you went with the desTroy plate.. Trust me!
I haven't burnt a servo up since I designed it and started running mine! ;)

As far as getting full lock, the right steering, etc.. that comes down to the amount of time you put into your setup.

Too much caster(past 15°) you lose steering. The inside tire gets into your links or shocks. Dependent on 8° or non 8° C's..

I was all 8° until I watched Dlux run, at World's 2015..
I Watched what difference it made!
I switched shortly after and watched what my rig was doing different.

IMO.. I wouldn't ever go back to 8°..

Unless it's on a scale rig.. My C1 Troyota, C2 killer (TF2 modded with VP scx C's, knuckles and VVD's) and C2 scx XJ(VP wraith C's, knuckles and uni's) benefited enough from the amount of work I have put into them.

I put as much work into my rigs steering, as I do into the rest of the rig. If not more!
All are modded uni's, full lock to lock steering, matching EPA's(or dam close)

Agreed!
I run my rigs C's, around the 12°-15° area, for caster.
It's shown the most benefit, all around.

Some guys are around 20° or so and not only does it look crazy, but not needed. IMO..

Yes, it may help in the One spot.. but hinders in 10 more.. again, just IMO and what I Watch.


I Watch alot of rigs in Many states and just as many different rock types..

I've crawled in a dozen states, at comps, with guys from surrounding states and countries..
I watch alot of rigs run..

Quote me when you do.
I don't get as many notifications thru Tapatalk anymore, like it use to.

Re: Good turning radius? (Diameter?)
 

I'm following along I us the distroy plate and like it but could stand to dial in my steering better.

Don't you disTroy! Or I'll block your a$$ from texting me! Baahahaha...

Pics help. Straight, full left, and full right.
