It's a start! The steering looks good. If you can make a longer chassis, say 14-15" (and shorten the links to go with it) then you could mount the shocks directly to the axles. That should help limit your articulation; 60-70 degrees or 7-8 inches is plenty. That'll also lower the chassis overall.

The chassis centre height is 5" so do I have to lower it? Sorry for asking but why would I want to limmit the articulation? I drove it and it is stable on almost 90deg, please explane so I may understand....
Thanks.

I'm no expert, but the idea is that too much articulation means the suspension is too soft and there's less pressure pushing the tires onto the rocks. Keeping it at 60-70 degrees will give it plenty of pressure and grip. Lowering the chassis (to about where the lower links are parallel with the ground) will keep the center of gravity lower and help with balance.

I'm no Expert either, but I know from the comp guys that
most of the pro's use Fuel Line inside the shock to limit the
Shock from extending all the way.....


Looking good man

Keep Going

I fitted some e savage springs and limmeted the travel, there is one thing I wanna try and that is to load the soft springs so that when it is in rest the shocks is somewhat compresed and not fully extended. The boddy is gonna be that of the traxxas Jato, it looks sleek and low.

Limiting the suspension will keep it from unloading on steep off camber climbs. A limited articulation will keep the tire planted better and not flip itself over due to the tire continuing to lift due to too much flex. I think a shorter shock will be your answer. Link mounted shocks need to be shorter than axle mounted due to the geometry of the suspension. Not sure how long Jato shocks are but I know Revos are a good length. Looks like you're getting it figured out

Ok maybe a stupid question, but if we say 70deg articulation is that only one axle or is it total flex of both front and rear? Meaning one by compressing the left shock and the right fully exstended or is it the left front compressed and right rear compressed.
Sorry for being a total a%$.

It means front and rear at full compression/extension. Pick one front tire off the ground and let the rear suspension do what it wants until a rear tire comes off the ground. 70 degrees is still quite a bit.

Thanks man. Did it and see your point, it does make a big improvement.
Im working on a spring loaded 1/4 scale servo suspension lowering/ raising front and rear setup.
Here we dont have competitions so we can do pretty much what we want, dont know if its legal or not. Will post picks soon.
