Tamiya Semi - MAN Steering (Ackerman Steering Principle)

[aseejr]

Just thought I'd share this:

I was comparing the steering radius of my Tamiya MAN semi against my Knight Hauler. And thought, why the longer wheelbase truck (the Knight Hauler) had a tighter turning radius. Looked at this site first but couldn't find anything but found a thread on a build by Tamiya Cowboy posted on Scale.... , someone had mentioned correcting the steering geometry on short wheelbase trucks by moving the connecting steering rod behind the axle as opposed to the stock setup of being in front of the axle (Ackerman Steering Principle). Needed more explaining by Jordy (The Machinist) to get me convinced.

Tonight I moved the connecting steering rod to behind the axle and presto. Tighter turning radius. I would say it cut it down by 1/3 (maybe exaggerating a little). Before when backing up a trailer and I get a little twisted and you couldn't get the semi around fast enough to correct the trailer, well, not a problem anymore. Much more fun to drive now.
