RC Submarine "Open Diving Bell" Design

[Johnny28]

Has anyone used the open diving bell design rather than WTC for a submarine?.

I am in the process of starting to build one and wondered if anyone else has that could give me a few tips, rather than me reinventing the wheel.

1. You're going to need a lot of ballast weights to bring that air pocket down and keep boat upright.
2. Electronics constantly exposed to high humidity.

The Submarine (Motors, Hull, battery's etc.) weighs approximately 6 kilos. Total air volume is approximately 8 litres; I will have 2 litres of ballast. I believe that with these numbers (And some lead and Styrofoam) i should be able to achieve a neutrally buoyant sub at periscope depth.

Good point with the humidity, will look into how to protect the controller, absorbent desiccant or something similar.

Just put the water sensitive electronics like receiver, esc, pitch controller inside a watert tight container. The drive motor, servos and batteries can be in the wet
