Bump Steer --

A condition caused by steering linkage or suspension geometry, causing the steering angle to move due to suspension compression, altering the model's heading. Bump steer may be caused by a steering bellcrank or servo that doesn't match the angle of the hinge pin or king pin, unequal upper and lower suspension arm lengths, or a turnbuckle or tie rod that is at a different height inboard (such as at the ackerman link) than outboard (at the hub). Keeping all steering linkages at 90* to each other also helps eliminate bump steer. Increased bump steer may help a model recover after jumps, but too much will make it seem 'twitchy' in the corners, especially on rough tracks. Bump steer can be adjusted by raising or lowering the mounting location of the steering links on the steering arms with the use of spacers.
