Folding propeller
thingiverse
To create a compact electric glider, assemble a "fork" along with two matching blades using small bolts and nuts (possibly washers). The overhanging blades may pose challenges; for a secure bond, use 3mm filament and ABS glue made from acetone and ABS. After testing the setup with a geared motor, plan to fly it on a small Graupner Discus (120cm) in upcoming trials.
