As is, everything works, no leaks, includes Frisky TD R10 RX. Has 2.4 GHZ Rg178 antenna wire run thru the stern bulkhead, can be plugged. The batteries where spot welded have some rust. They can be replaced. I wired the connector wires to the bow endc ap to easily charge/turn on cylinder without needing to pull out the electronics tray. I no longer build small submarines, so wanting to sell it. Does not include fittings kit. Does include charging cable and extra O'Rings for stern and bow endcaps. $300
