What a great site. So much information on PT boats! I've scratch-built a Vosper MTB at 1/14.6 scale making the model 60 inches long. It is RC and powered by 3 Johnson 18VDC drill motors. I used the Revell 1/72 model as my reference. The boat has been running for several years as I continue to work on details. The torpedoes are operational, powered by a Graupner Speed 300 motor on 4 AAA cells in series. A coil spring pushes the fish out of the tube. A magnetic reed switch turns on the motor as the torpedo clears the tube. I've documented the build on my web site at:

Go to "Hobbies" to see the boat in action and still pictures of the build. Since it's an odd scale, everything is scratch-built including the life rings, life raft, 20mm gun, .50 cal mounts, and just about everything else. The boat is equipped with all working and running lights. I run it on a 6-Channel Hitec ground radio. Each motor has it's own Proboat ESC. The three rudders are turned by a pull-pull cable system powered by a Futaba sail servo. Both torpedoes fire at the same time as on the full-sized boats. The last bit of work is underway to build operational depth charges. Working on the permits to arm them with a small amount of black powder for effect.
I've taken a few liberties in the design so it isn't exactly to scale in the layout of the mast. Other than that, it's a Type A1 Vosper built in Rhode Island for Lend-Lease and used by the Russian Navy in WWII. British boats didn't have Browning .50 cal machine guns or the compressed air firing mechanism for the torpedoes.

Mike . . .
You had the coding right for an image (photo), but your link was to a web page not a photo so I changed your image code to a url code instead. The link now takes visitors to your boat build slide show.
Nice job on the Vosper.
