This is the Mk2 version of our tail wheel upgrade kit for the Alchemy, Alchemy Pro and Allure Bipe.
We replace the 3D printed Bush with a machined Delrin Bush, replace the coil spring with a piece of spring wire soldered into a brass coupler. The pin that screws into the rudder is machined from Delrin. Also supplied is a carbon spacer to go under the factory supplied alloy retention bracket.
The tail wheel pictured is also manufactured by us and sold separately.
The spring wire is secured to the tailwheel axle/spring with an M3 grub screw. This should be Locktited during assembly. It also helps to file a small flat on the axle/spring to seat the grub screw.
