Wind Up Engine for Paper Airplanes

OverviewI am really glad with my propeller and rubber band system that firstly used in my Flying Fairy https://makerworld.com/en/models/13166#profileId-13986 .I wanted to use it in other projects as well, so this is my rubber band engine for paper airplanes :) Instruction of assemblyTo use it you need paper airplane. I tested it mostly with this model.However after make it you have to cut “nose” of the airplane and you can strengthen it with tape like at gif below. This step is not necessary but make easier snap paper airplane into frame and prevent paper before damage.If you have airplane then bend propeller blade about 45 degree like on photo belowAnd slide the hook of the propeller into hole of the frame and attach rubber bandsNext slide whole engine into airplane using bottom catchWinding upTo start flying you have to wind up rubber band with propeller. You can make it simply with finger or use my tool for electric screwdriver.<img src="https://makerworld.bblmw.com/makerworld/model
