This is the four foot Sterling model of the Chris Craft Corvette with sound module installed. I was able to reupload the video after using "Handbrake" software. Appears youtube doesnt like lower resolution videos.

Here's a heavily modified Seaport Workboat - Toby. Videos to follow - the crane now works in three axis, and it has sound courtesy of a Technobots sound module. The searchlight works, as do the radar, running lights and nav lights.

Restoring my 46 inch fire boat bought from ebay currently stripping it back as paint was letting it down was running a graupner 600 turbo motor but changing and adding sound module and working fire monitors.
