Installing the Ballast Tanks and Associated Hardware

At this moment, the ballast tanks are just sitting in the hull and have not been permanently installed.

Here is a view of the forward tank just aft of the CO2 bottle. The Clippard air-operated valve will be used to vent the ballast tank.

The aft ballast tank sits just forward of the aft battery in between the WTC's.
Here, you can see the proposed organization of the hull with the ballast tanks as close to center as possible. Minor adjustments may have to be done once the hull is in the water for the first time during trim/waterline tests.
I tested the ballast tanks in a tub of water to time the vent/blow operations. The Clippard air-operated valve (used for venting) worked fine, and it took 7 seconds to completely vent the tank. At 35 lbs. of pressure, the blow operations also worked fine and took about the same length of time to completely fill the tank.

Since I was testing the Clippard valves, I also decided to test the Automatic Failsafe Unit (AFS). Simply turning off the transmitter (losing radio control), the AFS activated the vent operation after 7 seconds. This is precisely what was supposed to happen.

Additionally, turning the transmitter back on (regaining radio control), the AFS de-activated the vent operation. Again ... precisely what was supposed to happen.
I didn´t use CO2 to test the tanks, but rather air-pressure from my compressor ... less expensive. I will eventually have to test the entire system using CO2 to calculate the number of vent/blow operations possible with a 9 ounce bottle of CO2.
Here, you can see the tubing connections for the system supply (center) and the forward ballast tank. The bottom tube is for the blow and the one above that is for the vent.

Please be mindful that these are only temporary for the moment. Eventually, the tubing will be pushed onto the brass tubing until it touches the silicone sealant. I may even install clamps or wire ties if they become necessary.
