<div id="yui_3_16_0_ym19_1_1466982389727_2659" dir="ltr">I am going to try to make a gyro compass, looks doable. I don't care about what direction I am going-I just want to go in a strait line. I will point the sub in the direction I want to go at the surface, then turn on the gyro and sink. Then I can just follow the gyro.</div>
