Steering Improvements
- Thread starter Hammer!
- Start date
well the tire does swing up in an arc.. so you would expect the top of the tire to be closer to the shock at full flex.. mine at full flex is about 1/4 inch from the shock.. if you didn't put spacers in to tighten up slop in your links it's possible your axle is shifting over a little which could explain why you have less space.. or you might have more flex that I do which would explain it as well.. but if you talking about what I think you are.. it's normal whether you have cms or axle mounted steering or 3 link or 4 link.

I haven't done any xr mod to get more steering...I cant turn anymore before my tires hit the frame with small 1.9 tires none the less and did it with a simple screw change , some simple grinding and a cheap set of universal axles...and use a servo with less than 200 oz in. of tq. with no problem what so ever with burning up servos...If I tried 2.2 tires the tires would rub the frame on the inside backs of the tires at full turn...the 1.9s barely clear already.
Again..to eaches own on an XR mods or magical mods to fill a need for competitions.
So instead of just throwing around your opinions about something you haven't even tried.. and that wasn't even brought up until page 7 or so.
Why don't you actually answer the OP's initial question.. and tell him how you modded your steering.. and what cvds your using and how well they are holding up?.. you did read the rest of the thread right?
Also.. you missed in the Pros - SORRCA scale points -5 for CMS. "thumbsup"[/QUOTE]
lol..guess I lose with points all around then..i have no scale items or any special point items as I don't comp. so I don't care really.
I saw the cms discussion..didn't read the rest..i already know what it consisted of without having to read it all...Its pretty predictable.
I did however see where I think the op said he wasn't after an xr mod..this isn't exactly something the masses can do without some experience with some tools and general know how, and most definitely not something I would recommend to a noob personally.
I removed the screws on the front sides of the c hubs..ground down a few millimeters of the raised section then used grub screws to replace the stock screws, cut them to size to hold it back in place as you don't want them too long rubbing against the universals...ground a small section from the knuckles for added clearance and used a cheap set of 22 dollar integy universal axles to replace the stock ones.
How has it held up.?.well ,over 6 months and nothing to report as failures...Its no extreme steering XR mod but it gave me a few degrees more turning radius and I can actually take it even further but I don't care to over stress the axles..Thats why you need very strong expensive axles with an XR mod as they can take the added joint loads better than the lower cost axles can...but trust me the expensive axles can and will break eventually..i just don't care to pay the cost to replace them.
Don't forget a super high torque servo as well ..the loads put on those are excessive to have that kind of steering radius...anything less than an expensive quality high torque servo will generally be toast in no time.
A CMS puts more stress on a servo.
Read the SCX10 performance thread I wrote (its in the scx10 section) and you can see more about what I did to mine for less than 25 dollars..I don't know how it would work with a CMS at all ..so if you or anyone do what I did with a cms installed you're on your own if it doesn't work out for you.
You are right about I never installed or used a CMS...i don't have to ,to see other cons it presented to me personally...If I can see something glowing red hot, I don't need to touch it before im convinced its hot.

By the way..the failures I haven't experienced are using the stock knuckles and c hubs and an old 10yr plus ,old hitec servo with less than 200oz of torque...I would venture to say the stock servo with a bearing mod would still be in the truck had I gone that route.

I can have full compression of the suspension and turn fully to one direction or the other and have no rub although im millimeters from that happening even against the shocks and I have mine mounted in a fashion it wouldn't help the situation.
Did you take pics of the truck showing the problem?..if not you need to post some.

are those 2.2 tires?
I actually like where you have your shock mounted on the shock tower but this is causing your issue with the tire rubbing against the shock.
move your shock in one hole towards the front and see if this gives you more clearance.

What cms did you use? That mounting will cause all kinds of issues with bump steer and unequal turning radius from left to right...
I would get the rc4wd cms kit...comes with mount,panhard and link for a very nice setup...
This is mine..i will post better shots when i get home

ok,,if they are wider than a flat iron I can see them rubbing there,,,mine just barely and I mean barely by 1-2 millimeters clears my shock with my added steering and my shock is angled down much farther than you have yours..so it may be a tire issue for you in general.
I still cant tell you what the cms is doing to increase or even decrease your stock radius however if any.

Well i can see its not oriented correctly to work like it should..the link from the servo to the knuckle should be more in line or parallel with the tie rod from knuckle to knuckle...it looks like its pushing more than pulling at that angle...

Rc4wd is a much better design....i will get better pics in a little while for you..my cms has no bumpsteer and turns as far as possible with the given stock design..

You fix the cms issue...your steering will be fixed as well...the cms is causing your issue

I think hes right bud..if you have links all out of whack you peeing in the wind...If your tires are stock width you shouldn't be hitting the shock like you are...I just noticed it hitting and thinking the tires were a lot wider in general and assuming the cms was correct....if your links are off you cant go any further until that is resolved.
I unfortunately have no CMS experience so I need to bow out with helping setting it up properly
If you really must have a cms then wait for the help...if you don't then take it off and be done with the headache...follow my steering improvement tip and head to the trails with increased steering.

right so, what? i get a whole new CMS? and for the links, what do i do for the tiny little gaps...? and I'm pretty sure the CMS doesn't affect how the tires hit the shocks. ugghhh this is so annoying. anyway, I will make sure that I fix the spaces in the links, and (not as soon) get a new CMS, if thats what your telling me to do.
