FlisKits MMX Crayon Build Part 6, Fin Glue and Shock Cord

Line up the launch lug on the marking guide and mark for the fins.







A thin line of paint was scratched off for better adhesion.
The scratched line was just a little shorter than the root edge of the fins.

A drop of medium CA was set down on a scrap piece of cardboard.
Just the root edge of the clear fin was dragged through the drop.

Set the fin on the scratched line.
Start with the corner of the trailing edge even with the end of the tube.

The other end of the shock cord got an overhand knot.
There isn't enough room between the engine mount tube and the inside wall of the BT-3 crayon tube for a full square knot.
This overhand wrap will hold the Kevlar when it is set into a glue fillet at the base of the upper centering ring.

The streamer is taped onto the Kevlar line.
I try to arrange the model so the upper section won't be swinging and hitting the fins or engine mount when the model is hanging by the streamer.

The 12" streamer might be a little long, we'll see how easily it slides out of the upper section.
When prepping for flight, put the shock cord in the upper crayon section then follow with the rolled up streamer. At ejection the shock cord will be above the streamer and help pull it out.
