Drive and Steering FINALLY! The steering and drive systems took significantly longer to design and install than I was hoping, mostly due to many many mistakes, miscalculations, and lack of adequate planning. Very frustrating. Note: The orange cable in this picture goes from a battery on my work bench to a motor driver to test the drive system. Steering The steering system is electric with manual tiller backup. The black and white parts are 3D printed on my printer. The blue and silver blocky thing is a waterproof giant scale servo from the Radio Control (RC) hobby world. It has gobs of torque for being so small and should be strong enough to turn the rudder. It is back-drivable so the tiller can be used to steer, without removing the servo. However, for electrical-safety reasons the servo's cable must be unplugged before using the tiller. The tiller is made from a large red oak board that I think came from Scholar's Retreat, aka THICUT, aka what used to be my grandmother'...
