just to confuse things more....
main motor on the left stick ; forwards / Reverse
Ruder on the right stick ; left and right
connected onto the same channel as the rudder on the receiver with a "Y" cable the bow thruster ESC, between the output of the ESC and the bow thruster motor, a universal reverser twin switcher...
with the switch in the forward position the bow thruster works with the rudder to make a tighter turn.. left or right and fully proportional..
with the switch in the center ( Off ) no power goes from the ESC to the bow thruster motor, so you only have rudder movement..
with the switch in the reverse position the bow thruster works in the opposite direction to the rudder movment, this is handy when reversing.. helping to stear the bow in the direction the rudder would like to take the boat..
with the switch in the reverse position and driving slow ahead, you can then traverse.. (sideways diagonal)
this way you do not need to think about which way the bow thruster needs to operate and on which stick... you just need to know .. am I driving forwards or in reverse..
just something to think about... I have used this setup in a few of my boats..
