R/C Sailplane Retractable Landing Gear

thingiverse

Retractable gear built for a Radian XL Sailplane, designed after my LS6 sailplane's full-size retract system. Although I now think it would have been better to create fixed gear for the Radian XL, this design is cool and seems to work well, so here it is. It uses a 1 3/4-inch Dubro wheel as I recall. Aluminum Pop Rivet Shafts about 3mm in diameter (1/8 inch?) were used for the Axles/Pivot Points of the Gear. The Photos/Video are of an older design that needed to be trimmed down and lightened for the Radian XL. There are also provisions for gear doors, which I never designed. An Autocad DXF file is included with some earlier versions of various parts and geometry motion diagrams. https://youtu.be/9Sae3iCdemM
