Estes Mini Mars Lander Build #0881, Part 2, Engine Mount

Nothing out of the ordinary yet.
A 1/8" notch for the engine hook and a wrap of tape for retention.

The instructions have you open up the shock cord tie slit after the rings are glued in place.

TIP: It's much easier to widen the die-cut slot before gluing onto the engine mount tube.

Here's the before and after widening the shock cord tie slit. It doesn't take much, just enough for the shock cord to slip through.







The lower centering ring notch needed to be cut a bit deeper for the engine hook movement.
