Vintage DENNYPLANE JR. PLAN + RC UPDATE ARTICLE for BUILDING 72" OT FF Model - $19 - (Birmingham, AL)
I AM NOT SELLING A KIT, only a new, full-size copy of the PLAN for a DENNYPLANE JR. to scratch-build this historic model plane for yourself. This magazine cover from 1939 shows teenage movie star Mickey Rooney releasing a Reginald Denny DENNYPLANE JR. Reginald was a Hollywood actor in the 1920s, 30s & 40s who also owned a hobby shop. He had a custom of giving a completed DENNYPLANE to child actors who appeared in movies at about the same time frame. So likely Mickey Rooney was a recipient of one of those completed models. The wingspan of this famous vintage, semi-scale, free flight model is 72". MOST patterns are shown on this really large PLAN with the exception of some fuselage cross braces. The model was based on the 1928 Stinson SM-2 Junior straight-wing executive aircraft that was popular at that time and was often used by Hollywood in its many aviation movies in the 30s. In World War 2 Reg Denny pioneered RC target drones for aerial gunnery practice. This great Old Time Ignition Engine Free Flight was updated to 3-channel RC on this PLAN. The PLAN includes the location of RC servos, engine thrust and beefed-up construction to take the strain of modern high RPM engines. Any .25 to .35 engine will do. The long-stroke ignition engines turned long props about 6-7,000 rpms. So the strain on the wing spars was not great. Newer glow engines are short stroke and turn shorter props at 13,000+ rpms. The plan also shows additional wing spars and bracing that ALL OLD TIME FREE FLIGHT DESIGNS need when they are converted to RC and higher RPM model engines. Old time free flights were first converted to rudder-only RC control as trainers and the wings began folding up in flight. So we quickly learned to add (1) hardwood full length spars to replace the balsa spars from the 1930s and 40s, or (2) extra full length balsa spars. Then when elevator and throttle controls were added for a full 3-channels this extra beefing up of the wing structure was absolutely essential. I got…
