Tail wheel assy is super simple. I used a 1/4x20 nylon bolt about 1/2" long, drilled a central hole in it for the wire. A hole was drilled and tapped on the bottom of the fuse to accept the bolt, which was locktighted in place.

The tiller is something I've done for a long time too. The 4-40 bolt that secures the stop collar also as steering tiller. I add a short fuel line extension and secure onto the rudder with a cup fashioned from a 1/4" metal tubing. A pair of screws installed into short nyrod inner pieces in the rudder, complete the assy
