Happy enough with this 3D printed steering bit. Next to add a servo and attach to a base plate of light-ply.
The bits...
Bend the top of the 2mm nose wheel wire 90 degrees - the slot in the control arm is 15mm long. Fit into the control arm.
Thread through the inner part. At this point fix the the base plate using the three screw holes
Then the cover is fitted over to secure - its a tight fit so maybe gluing is not required .
