The BIG Fix, FlisKits MMX Crayon, Part 1

On it's third launch, my Fliskit Crayon lost a launch lug and the rear centering ring. The clear fins had already been re-glued a few times. The CA glue used on the fins was starting to cloud up the root edges.

I didn't have another MMX centering ring or launch lug. Instead of waiting for a mail order, I'll fix it with something close by.

I've wrapped MMX centering rings before. It's easy to do with 110 lb. card stock.
A long strip was cut the same width as the ring still on the model.

A glue stick was wiped down the back.

This was wrapped around the engine mount approximating the outside diameter of the top ring.

To line up the wrapped layers, the mount was slid into the upper section Crayon. The wraps were pressed against the end of the body tube with the side of a hobby knife.

A white glue fillet was applied and the excess wiped off with a Q-tip.
Don't glue the ring to the upper section. The upper section was just used for positioning.
