The radio unit provides you with control over your sailboat by sending a signal to the receiver in the Sailboat. There are many Brands and Models to choose from.
When RC sailing, the radio unit provides you with control over your sailboat: on the rudder and sail trim.
The 2 ‘sticks’ on the radio are two controls.
Vertically moving the one on the left, you trim the sails in and out.
Horizontally moving the stick on the right, you send commands to move the hull’s rudder blade to steer the boat into the direction you want.
On your rc sailboat are 2 servos, one each receive the signal off the two controls.
The steering servo actuates the rudder, through direct linkages.
The other will be hauling in and letting out the lines that controls the position of the sails. At its shortest length, the sails may only have a few degrees of sway. With the line fully relaxed, the sails could approach 90-degrees of travel.
To use your controller unit to sail your sailboat is really simple.
Turn the hull to the right by moving the rudder joystick to the right.
Turn the hull to the left by moving the rudder joystick to the left.
Pull the sail In by moving the sail stick down.
Ease the sail out by moving the sail stick up.
By manipulating the controls of the radio unit, you will sail your model from the piers as if it were a full-size yacht.
The distance to which you can sail your sailboat is limited by the range of the radio transmitter and receiver in the control system and by the capability of your eye. Visibility is crucial for sail trimming and steering to provide directional control to the hull (also for avoiding collisions).
