Model Submarine Depth Controller

• Dimensions are 1.3 x 1 x 0.5 inches.
• microprocessor control
• Uses a solid state pressure sensor
• can be installed in a compartment where pressure changes
• servo limited to 50^o travel
• One touch to NULL at the surface
• reed switch wander permits NULL by magnet swipe outside the sub hull
• compensates for transmitter stick misalignment

The depth controller actuates the submarine's forward hydrovane servo for precision depth control down to a 1 metre limit.

The purpose of the depth controller is to prevent the model submarine porpoising and allow realistic movement at periscope depth and decks awash.
