Dual Throttle Radio w/ Receiver
Harbor Models Original!
This radio has been modified by our technicians in the U.S.A. for maximum steering control. This has been accomplished by replacing the left hand joystick with a new Robbe Twin Throttle control. It also required the installation of a specially designed Printed Circuit Board, wiring re-configuration, and fine tuning of the system.

Features:
-6 Channel (left sticks: vertical for dual motor control. right stick: horizontal and vertical. switch: for momentary or latching. proportional dial: for bow thruster or other proportional controls)
-2.4GHz Transmission Signal for long range with no interference
-Reciever included
-No binding necessary if you use the provided receiver. Binding is necessary if you use more than the provided receiver or if the receiver loses its bind.

Note:
-The “Recharge” port does not function. Use 8 disposable AA batteries or re-chargeable batteries charged on an independent charger.
-The Green Power LED flashes Red when the batteries reach 10 volts or less.

Single Relay Switch
BattleSwitch is a relay switch that you toggle via hobby radio control gear. You can use DoubleSwitch to quickly and easily control lighting systems with two different voltages, motors, pumps, smoke generators, sound units and more! Will also control glow plugs and BattleBot weaponry. You can activate applications with voltage levels as high as 240VAC without having to know anything about microcontroller logic levels or transistors because the relay offers full electrical isolation from your receiver electronics.

BattleSwitch plugs into a standard hobby radio control receiver as easily as a servo does. You connect the load that you want to toggle using BattleSwitch's wear resistant screw terminals. Depending on the channel you use, you will then be able to control the relay by moving your radio's control stick up or down, left or right, or with a switch on your transmitter.

BattleSwitch has a status LED on the bottom. The LED will light up when the relay switch is on, and vice versa. It will also tell you if your radio link is too weak by flashing repeatedly.

The relay is a single pole double throw switch. Its typical lifetime is 100,000 switching cycles, depending on how heavy a load you are using.

BattleSwitch does not supply power at the screw terminals.

SPECIFICATIONS:
Maximum current: 10Amp @ 28 VDC
Dimensions: 1.25" X 1.25" X 0.9"
