3mm Carbon fiber Steering Arms - Axial Wraith/XR Knuckles

Designed to fit Axial Wraith and XR knuckles
Optimized Ackermen

Ackermen is defined as:

Quote:

Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.

Quote:

A simple approximation to perfect Ackermann steering geometry may be generated by moving the steering pivot points inward so as to lie on a line drawn between the steering kingpins and the centre of the rear axle.
The steering pivot points are joined by a rigid bar called the tie rod which can also be part of the steering mechanism, in the form of a rack and pinion for instance.
With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point. Note that this may be difficult to arrange in practice with simple linkages, and designers are advised to draw or analyze their steering systems over the full range of steering angles.

We have found what we believe is an optimized steering arm that creates a better, truer Near Zero Ackermen.
Doing so helps maximize steering angles found most beneficial in the Shafty class where dig units are not allowed.

Red line is what we consider crawler industry zero ackermen - Yellow line is our improved closer to true zero ackermen.
