I'm trying to reduce the pile of kits waiting to be built and am working on a Stretch Blobbo kit that have had for a few years. It comes with a steel fishing line leader for the shock cord mount. How well do these hold up to the heat, flame and corrosive residuals of ejection charges? It is covered with a plastic tube (heat shrink) which will protect the metal, at least for a while. Also I'm modifying the design of the motor mount a bit, I'm stretching it to take the E9 motors and also adding another centering ring so the fin tabs can be filletted on the front and back as well as inside the tube, and I'm going to bring the steel leader out at the side of the forward centering ring, by the wall of the body tube, rather than have it come right up the middle, so it will be a bit less exposed to the ejection charges. However I am somewhat concerned that it may corrode and break after a few flights. Has anyone had any problem with these?
