The engine hook retention is a wrap of black electrical tape.
With the coupler slid in place with no glue,
you can see the tubes weren't cut flat.
On the right is the tubes after sanding the ends square with a block.
TIP: Note the pencil lines. I marked the best fit after rotating the tubes. The pencil lines give me a reference when gluing them up.
Larger tubes are hard to cut clean even for a vendor.
Be sure to square them up with a sanding block with 220 grit sandpaper.
TIP: Bevel the ends of the coupler for an easier fit. Bevels also prevent the inside tube ends from peeling up.
