We looked at the signal on the tether output port on the transmitter using an oscilloscope, and it's a nice 6 channel PWM signal, on the red and green wires in the 4 conductor connecting cable.

I wonder if we can do some more compacting work to be able to fit more stuff in the robot...it's getting crowded in there! Wires take up a lot of room.

What current are you drawing with 12v and max. thrust? per bilge pump?
