Chassis tip/lean/sideways. How to fix?

[RcBro]

Hey Guys. I've basically finished my crawler but upon driving, the fram seems to tip from one side to another. Is this shock location, shock oil or spring setup, or link location?

Here are some pictures of the truck to give you an idea on how its setup.

And here is the video. This was the first time I've driven the crawler.

OMG! It is your shock setup :lol:

Seriously, move those to the A-arms.. After you do that and it still needs more tweaking, play with shock oils.. I have ran 60-80-100wt oil in my shocks before

Should I move them closer or mount them directly on the links?

They are not long enough to mount directly on the arms and the chassis.

Then move the upper mounting posistion closer to the axles. All shafties have horrible torque twist with link mounted shocks.

Run some longer shocks like x-factor's that what I'am running, also like twisted said go to a heavier wt oil and get some spring that more stiff.

Thanks guys. I added some thicker spacers to all 4 shocks and then moved the front shock closer to the axles.

All twist is eliminated completely now. And the truck seems to drive ALOT smoother and even turns better!


Thanks a bunch for the suggestions!

Lol man... I am glad you showed me that, I planned on puting my shocks on the links, but now that I see that... lol!

Possable easy fix !!

Looks like you've done some great work there man.

First off, your struts are fine, your link geometry looks good, and your steering looks very capable. DO NOT GO RE-ENGINEERING YOUR RIG!

I had this same issue with my 3 link rig. You problem is torque roll.

If your using a single motor on on your EMAXX tranny you have to move your engine to the right (passenger) side. Basically, if the motor is pulling the drive gear it will pull the car along with it.

I know this sounds far fetched, I still can't grasp the physics of this, it really shouldn't make any difference where the motor is placed, but try it, if I'm wrong you can easily move it back the the left side.
If I'm right, then you've not changed your whole car for a simple physics error.

Good luck, the rig looks great!

PS: I have a little cage buggy envy after looking at your rig, cudo's.

I have no torque twist at all in my Maxx. The shocks are mounted to the suspension arms and the motor is on the passanger side...

Thanks for the kudos. I've since fixed the torque twist. I simply moved my front shocks alittle closer to the main axle and used some thicker shock oil.

Now I have a traction issue and thats about it, small diff clearance but I can fix that by adding some full length skid plates lol. Seems to just get caught up.

Just need some tires, but I may just sell the rig, we'll c
