In the process of restoring a Ziroli DC-3 for the air museum at Hobby Airport in Houston, Texas. Plane was donated to the museum by the family of an model builder/flyer who has passed on and worked as an aircraft mechanic for Trans Texas Airways. The museum ask our RC Club if we could finish the build for the museum and paint it in Trans Texas Airways colors. The finished model will be displayed in flying condition and hung from the ceiling. I am selling these for the museum to help fund the completion of the aircraft. The retracts were fitted when we received the plane however they were new when installed. They have not been used so the condition is new. I will need to box them for shipping as the original boxing was not received. These pneumatic retracts are designed exclusively for use in Ziroli DC-3/C-47. Aircraft steel and aluminum construction are used throughout the retract mechanism. Other features include positive up and down locks and 1/4 steel axles. Also included is the fill valve, the air valve and a few retaining nuts. Asking $475.00 obo shipped to your door in the lower 48.
