Flying Engine Mount Build, Finished

I forgot the launch lug holes!
You won't need a launch lug on this one. Two holes in line through the centering rings is all it takes.

Ideally, the holes should have been punched before the rings were glued on. My rotary punch doesn't allow me to get close enough to the engine mount tube. It'll still slide on the launch rod and launch normally.

The bottom ring was punched. A launch rod was slipped through and turned against the upper ring leaving a mark for the second punch.

Here's how the launch lug fits.
This flying engine mount should be flown with A10-0t or A10-3t engines.
This is a tumble recovery rocket. Call a "Heads Up" before launch.
