Nice looking boats! Can't wait to see your progress on the Lotus as I pulled mine down from the rafters.

Nautilus Drydocks - Yesterday's work

Lots done yesterday!
SubDriver MKIII prototype is about 60% complete. This will be a 250/250/250 variant, 2.5" in diameter throughout the entire length. This photo was from the morning. I have the motor bulkhead complete along with the pump bulkhead. I should be able to get most if it done today if things go well.
More work on the Hunley prototype. Getting close to linkage installation. The challenge is going to be converting the linear action of the rear servo to rotary action for the unique rudder arrangement. Any ideas on a simple solution for this?
Upgrades for Mike Martin's Type VII are underway. I'm actually pulling the entire cylinder and installing a 3" unit, which fits nicely. This will have a working sound system as well as LED lighting. If I can swing it (and there are NO promises here), it will have at least one functional torpedo as well!
I spent the last 30 minutes of the day selfishly on my Orca. I pulled out the cheap, nasty Chinese LEDs and started installing newer, scale-looking one. This will have a Pittman 12V drive motor. I modified the rudder support to actually allow the prop to spin properly. Note the scale "Bruce" in the background. I have a crazy idea to RC that shark so that someone could actually chase the Orca with it! Thoughts are rolling around for a quick, dynamic diver... Gears are turning!

BTW one of our club guys is using a set of real piranha jaws on the flybridge and it looks awesome! (the shark was named Bruce because Steven Spielberg's lawyer was named Bruce)

Or you could go this route

Standard cylinders run the linkage straight out the back of the unit, typically attached to a rudder arm. I could tear into the bulkhead and re-mount the servo, of course, but customers won't have the expertise to do that, so I want to keep the standard arrangement and work out a conversion of linear movement of the linkage rod to rotary movement of the rudder arm.
Bob"... well, that takes care of Jorgenson's theory!"

That said, I've already got functional 48th gas torpedo prototypes. Gas weapons are cheap, fast, easy to produce (and they make such cool bubbles when they fire!).
Most of yesterday was spend on customer orders and further assembly of the MKIII SubDriver assembly.
