Second, is the Robart tail wheel retract mechanism. I was having problems with retracting the gear. The weight of the plane pushed the wire gear up. This interferred with the lever/toggle system of the retract. I solved this by grinding another flat spot on the wire and putting a small wheel collar under the mechanism.
Am I the only one having these problems?
I used a small zano saw to cut the rearward bulkhead out and then yanked out the mounting plate from the foward bulkhead. It's two pieces of plywood glued together and comes out easily. I then mounted the wedge to the plate and the gear to the wedge with the supplied screws. I used a piece of hardwood epoxied to the mount plate to attach the non moving end of a robart 1" air cyl.

I ran the two air lines to the rear which elimanated the need for the "hi-torque" servo, y-harness, long control rod and associated hardware.
If you set up the air system correctly, the retract will cam over and lock down. That takes the strain off the air system and the retract cannot fold up accidently.
