Yet another way to do it. I wanted to be able to use it in the future when I do aerobatics but for now I just want it secured but still have it coming through the panel.
The bolt in the first picture can be replaced with a pin in the future. For flight with parachutes, pull the pin before closing the canopy. It will be part of the aerobatic checklist.
but it still comes through the panel. The hole in the panel has been relocated slightly lower.
