ORIGINAL: Radical Departure
I'm considering using ball links and rods to tie the steering arm to the tailwheel.
HM,
Solid rods cannot be used in this layout.
An elastic connection is needed on each side because the up-down flexing effect of the supporting strap would be annulled, and/or the rods could be bent under a heavy landing.
As John explained, the caster of the wheel makes it more powerful respect to the linkage, and stronger springs are needed.
