I began to modify the engines so they can receive LEDs : opening of the nozzle (leaving a small lip to hold the photoetched part) and removing one of the two studs. The second is kept as a support for the led.

A quick wash with Tamiay extra liquid glue dissolves all remaining dust.

To hold the photo-etched nozzle, I needed to add matterial to the small lip (in some places where I sanded too much), and the photoeched parts are installed.

The inner faces of the engines receive a layer of surface primer and black, followed by a silver drybrush on the viewable end.

Plastic films from the upgrade kit and LED are installed with white glue.

And everything is closed.
