If you set your steering travel at 20degrees left and right then that would be the same regardless what ackerman you are running

I was just thinking that it would require more travel to take advantage of ackerman setting moved forward. From what i see the more you move the inside link forward the more toe out the car has at full lock.

So your saying not to adjust(reset) the steering once changed the ackerman?

I don't know how the laws of physics of whatever work on this, but I find that when I move the steering link forward on the plate, the steering is more responsive and aggresive, throughout the turning circle. I think that this is because, the further forward the link is, the more responsive it is to movements from the steering rack and hence the servo. I always reset the geomatry after adgusting the ackermann i.e if I had it in one hole and had 0.5* toe-in, after moving it I would reset the steering to this toe angle.
Hope that gives some insight.....

hi i need to ball type king pin for the front camber link that goes on the top steering knuckle
is the part number SD-414TA the titanium king pin, the ball type? or is it just the flat one that goes on the botttom? thanks

the stock king pin is part #sd-414b
or if you want ito to conevert, tot the off road ball cups and ball studs get # bx-414kb, ( kingpin) you will have to grind away about 2mm off of the sleve and at leat 1.5 mill off of the kingpin, other wase the threads will hit the drive axel, unless however you are planning on running the steering knuckle in the low position, then thre will be no need shorten the kinpin, ( i would still grind the sleve and us the kingpin coller ( part # sd-414c) what is really nice about using the off road kingpin is you have more threads in the steering knuckle, which in turn prevents the kingpin stripping out in the steering knuckle.

thanks pops,
doesn't ackerman, effect the inside wheel, as i turn the wheel on the transmitter and the wheels approach full lock, the inner wheel turns in and increases its angle faster i always thought this was ackerman, and the adjustment we were making was when and how fast the inner wheel did its thing. if i'm wrong, or have it backwards, well,,,,,, my bad.

What was Masami & the rest of the Yok BD used in the IFMAR, front Spool with center one-way?

I don't know either....inside or outside wheel. I read somewhere that its the arc thats changing??
So can some one answer first, is it outside or inside wheel??
Why have TeamYokomo drivers moved the ackerman plate 4mm further forward? what are they trying to achieve?

Hi,
the ackermann effect is one of the most interesting and most complicated things (right behind camber changes in the corner during damper action).
To keep it simple:
The inside tire should always be more angled then the outside tire. This is because the inside tire has to turn a much smaller turning diameter around the corner, while the outside tire doesn't need that much steering lock as the diameter of its turning circle is quite bigger.
I hope it's understandable... If not, please ask and I'll try to explain it in a different way.
@BJ: As the new C-Hubs and steering knuckle allow more steering throw the mounting holes on the steering knuckles are further forward to prevent wobbling at maximum steering throw. To keep the ackermann effect the same the holes have to be further forward aswell.
Cheers
Chris

That means....
My alum. steering knockle is semi useless with the new C-hub and steering plate.
