Not A Tri-Fold Mount - Tip

This type of shock cord mount feels stronger than a thin paper ti-fold mount. It can be used on BT-55 and larger tubes. I wouldn't recommend using this in a BT-20 or BT-50. In smaller diameter tubes, the shock cord knot might block the ejection of a parachute.

Cut a rectangular piece of body tube, from the same diameter as your main airframe tube.

Tie your shock cord around the rectangular piece.

 

Glue into the body tube with the tail of the shock cord pointing up. The rectangle mount is already rounded to match the inside curve of the main airframe tube.

Be sure to recess the mount deep enough to clear the nose cone shoulder.

This shock cord mount design was used in some Centuri kits.
