Grasshopper:....

The proper angle for the steering linkage will be the same angle as your upper A-arms to eliminate all bump steer. :thumbsup:

That is only true if the steering linkage is also the same length as the upper arm.....

Ace is right, I used to think just matching upper arm and tie rod angle eliminated bump steer, it gets you close but doesn't alway work.

Not necessarily ture here...there are other parameters to first thnk about.

I'm just trying to help out by making him first think about the front suspension geometry and steering layout. :)


There are a wide number of topics to concider when designing the front suspension geometry layout - kingpin inclination, wheel offset, clearance, camber change curve, static roll center height etc...if you want to get technical about it.

All this information is true and would apply if Flyinrc was designing the front end from scratch, ground up, clean sheet of paper but I don't think that is the question, I think he wants to know how much of a angle the tie rods need to eliminate as much bump steer as possible with the car he has.:cool: Is there a standard for just that:confused:

No.. each vehicle would be different. I thought I explained that above.

Ok New question. Tplate on an l4 fiberglass or steel, soft med, or hard? What will stiffening softening the center shock and t plate do?

What is the proper angle for steering linkage? I'm putting a new car togeather where I have to drill the servo mounting holes and have never given it much thought.

thanks in advance

try to get the tie rods so that they go just alittle bit infront of the rear screw on the arm.

here are a few pics of my Aggressor.


Ok New question. Tplate on an l4 fiberglass or steel, soft med, or hard? What will stiffening softening the center shock and t plate do?

stiffer on the spring gives the car more steering and works best on smooth hig grip tracks. softer gives less and is good for bumpy low grip tracks. on the tplate when running 3 shocks they really don't do a whole lot. a stiffer tplate works the same. when I ran a L4 I always ran the .075 fiberglass. now with my Aggressor I run the .063 fiberglass. the difference in thicknesses is supposed to react different. a thinner .063 will react faster than the .075. but like I said I really don't think that matters that much when running 3 shocks. if you are running tweek screws then you'll feel the difference.

I've always found that a softer t-plate gives more rear bite but it will depend on how bumpy the track is aslo

davepull, the upper arms in your pics, are those the CRC (Calandra) delrin ones?

yah they are pretty sweet. I also got the CRC titanium camber links

Good thread just bumping it up for myself and the other new guys.

yah they are pretty sweet. I also got the CRC titanium camber links

thoes are awsome what is the price on those?

I picked up their Alum Castor blocks, Delrin upper A arms and their side shock conversions. The shocks are the smoothest I have every built. It was simple too you didnt have to keep messing with the shock to get it to feel right.

I'm with ya on the side shocks Eric,I picked up a set also and they are superior to the sylva's and last and last.

What have they done to make these shocks so much better?

i think they use a delrin end cap that has more support built in. and they use the associated internals

Delrin cap so you dont have alum on alum.

You use all the Associated internals minus the star clip and the large washer.

Whats the part #'s for the CRC side shock conversion & delrin front upper arm. I just can't seem to find it on the website. Thanx

larry beat me. They are super smooth though.

they are very nice shocks..
