suspension travel affecting wheel toe geometry...

Has anyone here solved this problem?? - I tried a few searches but the search engine here seems a little finicky or something. "no matches" no matter how I word it.
I have an EVO truck with the standard stuff - lift kit, bearings, Aoshima's, etc. I got this thing as a way to relieve the boredom that sets in around here at my work sometimes. (My main "toy" is a TLT-based rock crawler, but this little thing is new to me)
My big complaint is how the front wheels toe out horribly when the suspension compresses. I've racked my brain on this one and I can't figure out what is making this happen.
I tried just pinning the front suspension, it keeps the wheels straight but the performance is so unacceptable that dealing with the toe-out is better.
I did find one thread with a tutorial on doing this but I don't want to limit the suspension travel if I don't have to.
In that thread though, there is a mention of another mod:

Or you can do Avants way which works entirely... No locking the suspension, full travel with 0 toe
Anybody know what he's talking about and can you post a link?
Or am I just expecting too much from this little truck?
Well, this is a setback - I started noticing some sloppy steering and looking into it found the left knuckle is cracked where the steering linkage screw hole is. There's going to be no way to effectively repair this, it would just crack again.
Oh, well - I have to keep reminding myself not to expect too much out of this thing. What can one expect for 30 bucks?
I've had too much success with it so far to shelve it now, for 15 or 20 minutes yesterday it was performing better than ever. Increased steering radius and the suspension still worked as good as it did stock, except now with very minimal toe-out effect.
I guess I'll look for some aluminum knuckles.
My camera is not cooperating today - I can't get a clear shot of the new steering linkage...
Hmmmm - this does seem to help. Actually quite a bit. Sweet!
I pretty much duplicated what I saw in the Mini-Z page.
This seems to have increased the steering radius to begin with - probably the longer horn I made from a piece of large zip-tie.
There is still a little toe-out when the suspension is compressed - but nowhere near what it was in stock form.
Now I have another idea... pics tomorrow...[/img]
Xmods are probably the easiest, and cheapest way to get started into the RC scene. Unlike the 1:28th brethren (Mini-Zs) they are not as expensive. But also unlike their brethren, they are not as "good" when it comes to "hobby grade." But Hobby grade comes with a price, you need to pay up to have the best.
IF you want a smaller RC crawler for just the workplace or small little obstacles, the Xmod is the way to go. It will just take some things. Like the Aoshima's you already have, the lift kit toe-out fix, and a motor with more torque. Such as a Sub-Micro-Servo conversion with the HS-55.
You'll have fun with your Xmods, I am sure. It will just take some time and money to get them to "your standards". Especially since you went from Hobby Grade, to Toy Grade. :lol:
That looks like what I'm looking for - thanks.
That's sort of what I figured, based on my experience w/ hobby-grade stuff.
I was in Rat Shack picking up stuff for my job, and noticed they were blowing out all the Xmod stuff. I got a Nissan Titan starter kit, lift kit/tires, and a Ford F-150 body for like 40 bucks. The guy kept tapping the keyboard and adding discounts, I could'nt resist.
Now I just have to get over the urge to re-design the damn thing, I guess!!
Thanks for your help...
Avant is a member over at MiniZRacer. Very knowledgable person.
To answer your lift kit question, no one has come up with a "perfect" way to fix it. Avant has come up with the most near fix thats perfect. He used a paper clip and created his own custom tie rod. Seeing as how the tie rod is the main problem with the lift kit.

That's the whole thread above.
More specifically to what you're looking for is this page. Which has pictures of how he did this modification:

Hope this helps. Also keep in mind that he is using a seperate PCB board, than what standard Xmods use. He is using a MiniZ or a Micro T board instead. I forget which it is.
Welcome to the forum, by the way. ;)

Yes, you are. :lol:
