Setting up the system

There are 2-3-,5-,6- Channel transmitters. Channels are the amount of things you can control. For instance a three channel transmitter means you can only control three motors/servos/accessories. A standard RC transmitter you buy for a RC plane has 6 channels. These channels are controlling the rudder, elevator, ailerons, motor, Aux 1, and Aux 2. So basically each channel controls a different servo.
For a yacht in most cases only 2 channels are used although most new transmitters will have 6

channels. The channels used are Throttle  and Aileron (Thro,Aile) marked on the receiver.

The winch connects to the Thro and Rudder servo connects to the Aile connectors on the receiver.

This gives sail control to the left hand up/down stick and rudder control to the right hand

left right stick.  

The connector Marked Batt goes to the battery

Important if you are using an RMG winch the Battery connects straight to the winch.

The  Batt connector on the receiver connects to  the battery out from the winch.
