My scratch built Radio Controlled Douglas DC-3 is in progress and I am currently working on the cowls for the 86″ wingspan transport/airliner. Usually, when a modeler uses retractable gear on a DC-3, they try and use a scale like “knuckle” type landing gear setup. I am using the Robart landing gear which was designed and used with the Top Flite Douglas DC-3. I am not using the pneumatic system like the Top Flite, but I am using a traditional servo with a push-rod system to actuate the gear. I am also using a slo-go servo speed reducer to offer a more realistic look and feel. Take a look at the video below to see how they work!
