Radio Transmitters and Accessories

Transmitters and Receivers for remote controlling model boats and ships.

DX8 8-Ch. DSMX Transmitter Only
Like its groundbreaking predecessor, the DX8 Gen 2 gives pilots a powerful combination of features and capabilities no other 8-channel can match. And for a lot less than you might think, too.

With 8 channels at your disposal you will be able to control in the following combinations:
-Four joystick movements, two vertical and two horizontal
-One proportional knob
-Seven switches, two 2-way, five 3-way

The DX8 gives you the ability to assign each channel to the type of control you will need. For example eliminating the horizontal movement of the left stick and assigning that channel to another switch for an additional on/off function. Virtually all combinations are possible with this versatile radio.

Includes:
-Transmitter
-Transmitter battery
-Battery charger with worldwide plug adapters
-Neck lanyard
-Instruction manual
-DX8 decal sheet

PROGRAMMABLE VOICE ALERTS
The DX8 lets you keep tabs on important functions without ever taking your eyes off what you're piloting. You can program voice alerts to call out what flight mode you've chosen or report telemetry information on demand. If an alarm goes off, you won't have to look at the transmitter display to see what's happening. The DX8 can tell you.

WIRELESS TRAINER LINK
This exclusive Spetkrum technology gives DX8 users the ability to wirelessly link up with other Spektrum transmitters and specially-equipped Spektrum FPV headsets. Once bound to another transmitter or component, ModelMatch™ technology will allow the DX8 to re-link without having to go through the bind process again.

With Wireless Trainer Link, you could:
Wirelessly 'buddy box' with another DSMX®/DSM2® transmitter when teaching. Link with specially-equipped Spektrum FPV headsets to wirelessly control head tracking and remotely change video frequencies.

250 Model Memory
The enormous capacity of the DX8's on-board memory means you will rarely, if ever, need to juggle models between transmitter memory and your SD card. The model memory menu is easier to navigate too. Only memory slots with model settings saved to them will appear. You won't have to scroll through empty slots or move models around if one is deleted. Because the DX8 uses the same AirWare™ software as many other Spektrum transmitters, you can share model setups across platforms with almost any Spektrum pilot.

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"
