Hi shipmate, on the boats I have built that needed a bow thruster I wired through a esc not an
On/ off switch . Most thrusters I have used run at 7.2 max.
Full power at the flick of a switch would probably spin the shaft in the thrust paddle.
There are thrusters that use props which may be o/k for instant full power but I would
Still use a speed controller.
Someone may correct me but that's how I wire mine.
The left & right can be achieved by using a Y lead from the RX rudder channel to the rudder
Servo and the bow thruster esc. Then when you operate the rudder stick the thruster will work.
Every time you use the rudder stick.
I always put mine on a separate channel.
