For low speed aka 20mph, nothing is really critical.

For above 20mph
+10 Caster
0 Camber or less for coolness
0 Toe In/out

Positive Caster helps you get a less "nervous" steering. Tho only to a certain point, to much Caster will make them nervous again.

This is for rearwheeldrive, for a fwd you would want Negative Caster.


All this info I got from RcTek

What Thunder said is exactly how we have ours set up and we can roll 40+ MPH down the road with zero sweat due to steering. The steering works well for us out in the woods as well. Win win!

Don't have any road vids (will have to remedy that) but here is some offroad racing that shows the steering works okiedokie offroad Very Happy

So caster should be exactly 10,
Camber isn't needed
the toes isn't needed
last, are these set for straight axles?
and does the length of the axle bar matter?

Not exactly, depending on what you are building.
And what set? And no.

Wow really 55mph? That's fast.

If you plan on running it like fearless on asphalt/dirt you will be fine with camber and toe in / out at zero.

If you feel it changes direction when running straight you can try some toe in, maybe 1 degree.

If you plan on running on a short grass or dirt track with mostly corners, I'd go on and try with some camber settings.

Thats the current gearing for it, so 10 caster, 0 camber, no toe in/out?
