Submarine Water Tight Cylinder V1.0

This is the heart and soul of my RC Cylops Submarine! This dive unit uses a seriece of cheap parts that can be bought on amazon and assembled into a functional dive system in a submarine. The sub is static diving meaning it has a working ballast tank like the real thing and can dive and ascend in place. It is very simple and in expensive as an intro to RC submarines!

Most parts can be purchased on amazon. Additionally you will need a minimum of a 30 AMP drone ESC and a 2204 low KV motor. I used 2300kv but the lower the better. The tail is made to fit a 2200 size brushless drone motor.

The sub Hull must be weighted in the keel with weights to properly sink the boat for diving. It takes about 1.9kg of lead or about 4lbs total lead weight to reach this. The structure becomes very heavy and needs reinforcement to withstand the weight.

All parts need an epoxy coating in XTC-3d to withstand long term use in water and the strengthen them for the load of lead weight the sub carries. The epoxy coat also ensures the PLA has no issues while sitting in the sun and seals the hull against the ingress of water. THREE COATS ARE HIGHLY RECOMMENDED

Segments of Hull are assembled using these melt in inserts. M4 socket head screws are used to assemble the segments.
