A little bungee launch hook for radio-controlled gliders and planes. OpenSCAD source is included should you wish to change any of the parameters.Print with support material, which snaps off easily for a change. Cut a thin groove in the underside of the fuselage ( to accommodate only the triangular section) and use glue of your choice ( I used hot-melt) to fix the hook in place at or slightly forward of the CG. Remember that the hook for the bungee should be at the aft-end.
