R/C Plane/Wing Simple Bungee Launch Base

thingiverse

This is a straightforward bungee foundation for your RC plane. The concept is that you attach it to the foam using hot glue. There are two versions, one with a flat base and another designed to be embedded into the foam. If damage occurs, use alcohol to dissolve the hot glue and replace the damaged part. You can utilize TinkerCad or your preferred design software to adjust the size as required.
