Hello all. First post since 2011. Since running DIY free-running model subs in the backyard pool as a kid. I've always in the back of my mind been interested in doing an RC sub. Recently, I saw the Moebius 1/72 Skipjack kit on sale on Amazon for $79 so I placed it on order and here I am. I've perused most other SJ builds for ideas and inspiration. I'm not new to RC, I've been involved with the RC tank and warship combat sides of the hobby for years now. So I know my way around custom RC systems work. I see that water tight cylinders are the norm nowadays. Since I'm hoping to use as much stuff out of my warship combat parts bin (and I don't have any acrylic tube in stock), I'm thinking of going a different route with this build. In warship combat, we use 150psi CO2 to power the bb cannons and we have various successful methods to waterproof servos and electronics. Most RC combat captains today no longer use waterproof enclosures for the electronics but instead waterproof each component. Since I've got all this stuff on the shelf, I'm thinking, why not build a sub warship combat style? I'll forego the WTC and use the CO2 system to move the ballast.
So for this build, I'm contemplating:
Can any of the experienced sub captains shoot any big enough holes in this idea to convince me to go a more traditional route?
Thanks!

So for this build, I'm contemplating:
- Free flooding hull, no WTC
- All electronic assemblies individually water-proofed
- "Hardened" off-the-shelf waterproof servos
- Direct drive 755 motor, open to the water (motor has Oilite bushings, no internal fan)
- CO2 powered ballast system
- 4oz paintball CO2 bottle with commercial off-the-shelf 150psi pressure regulator
- 24v power with custom ESC
- Warship combat trigger board to operate the ballast solenoid valves
- Vex 75mhz radio
Can any of the experienced sub captains shoot any big enough holes in this idea to convince me to go a more traditional route?
Thanks!
