LANDING GEAR: Tailwheel Installation Part IV

Updated: Aug 30, 2019

The final step to setting the tailwheel is attaching the steering springs. To do this properly, a special laser alignment jig is required to "shoot" the line between the tailwheel steering spring attach point and the rudder horn attach point.

I used a slightly different design than others posted on the forums. It just seemed to work better. I used some leftover angle aluminum, cut the rudder horn end to get the proper bend to the forward end of the jig, and then I attached a piece of 1/2" MDF cut at the appropriate angles to sit on the tailwheel steering arms. I made this universal so I could transfer the jig from the right side to the left. Once set on the bench, I just taped a laser pointer to the support angle and moved it to the place. Then just mark the intersecting point on the fuselage shell and drill through for the steering cables.

Once drilled, the steering cables get fed through some extra pitot static line to keep them from chafing the fuselage (or the fuselage chafing the cable). This pitot line gets cut flush to the exterior of the fuselage and provides a guide internal to the tailcone.

The final installation requires Nicopress sleeves swaged to the cables. Then tensioning of the dual springs from the tailwheel steering arms to the rudder horn.
