Estes Xarconian Cruiser Build Part 31, Intake Detail

I wanted to darken the inside of the rear intakes.
It'd be too hard to paint them now so I'll use some electrical tape.
The electrical tape will stay in place and is a matte finish.

While the picture shows the width to be 1 3/16", in the end the width was 1 1/8".

Use your long tweezers to center and set the piece of tape.
The tape can stick out of the tube a little.
After burnishing down the tape with a dowel, cut off the overhang with a razor blade.

Here's the rear intake after trimming the tape piece.
