Estes Paveway III Build, Part 5 Engine Hook Fix

Here's the before and after fixing the engine hook.

On the left, the engine hook is pressed tight between the tail cone and engine mount tube. The tube is compressed and not perfectly round.
A swelled engine casing would be hard to insert in an ovaled tube.

On the right, a notch was filed in the bottom inside edge of the plastic tail cone. There is enough room for the thickness of the engine hook and the tube is round again. Center the notch between two fin slots.
A simple and necessary fix.

With the tail cone and engine mount in place, the rings sit this far inside the body tube.
The motor mount tube was marked at the end of the main air frame tube.
A dowel was marked a little shorter so the upper ring would hit the glue ring before it was totally in position.

A ring of glue was applied around the top of the rounded dowel. The dowel is inserted into the tube and the glue rolled around using the pencil mark as a depth gauge. Three applications of glue were needed to get a ring around the inside of the BT-55.

I adjusted the engine mount height until the tube end was even with the end of the tail cone.
