Finish the tailwheel airplane?
Or of course, copy Alex, who has some great ideas here. I originally wanted the twist grip throttle, but could not locate one with a potentiometer spring loaded to center, the operating scheme for the fancy Sabertooth controller. Alex sidestepped the issue with the forward-reverse switch and a much less pricy controller. The differential in the axle allows turning without resistance, an overlooked detail. For example, the cheap tugs built with the snowblower gearboxes are indeed resistant to a sharp turn when loaded. Flip side is that one wheel may spin, but Alex has since run it in the snow and it does not seem to be a problem. Steering via independent motors doesn't have that issue, but brings us back to the human interface (currently a joystick) and controller choice.
