Calling Spektrum's DSM System 'revolutionary' just doesn't say it.
DSM is nothing less than a quantum leap in RC technology that will change forever how you communicate with your car or truck.

What is DSM?

DSM is Digital Spectrum Modulation—a purely digital RF link between transmitter and model that is based on Direct Sequencing Spread Spectrum technology. It operates within the ultra-high 2.4GHz worldwide ISM band, provides unequalled signal resolution, and is immune to the most common forms of RF interference. It will even allow your model to “talk” back to you. It requires no crystals and completely frees you from ever having to monitor frequency usage again.

Spektrum's no-pins, no-interference, no-glitch DSM 2.4GHz technology ignited a revolution among high-end racers. Starting with RF modules, we made it possible to adapt existing pro-style transmitters to this breakthrough technology for dramatically improved performance.

Now, we're introducing the world's first DSM 2.4GHz radio. With the new Spektrum DX3.0, you'll have a 3-channel system loaded with great programming features combined with built-in, ultra-fast DSM modulation. It couldn't be easier.

You'll never have to select - or wait for - a channel again. Plus, glitching from motors and metal-to-metal "noise" will be a thing of the past.

After installing the radio, all that’s left to do is spend a few seconds “binding” the receiver to the module and you’re ready to go. It’s that easy. The Spektrum DSM System provides an impenetrable digital RF link between a racer and his car that is impervious to all types of interference, including other radio systems, model generated interference or environmental interference from pagers, cell phones, etc.

Collision Avoidance- The DSM system scans the 2.4Ghz band looking for an open channel. When an unused channel is found the system locks on that channel and transmits providing the following benefits:
- No more waiting for an open frequency
- No need to impound the radio
- Eliminates the need for a frequency board and frequency clips
- Interference for other radios is a thing of the past
- No crystals are needed

• 2.4ghz worldwide band is approved for international use. No need to change frequencies when traveling abroad
• Built-in failsafe drives the servos to a preset position (usually full brakes) in the unlikely event of radio interference
• The DSM system literally plugs into popular module based 3-channel transmitters allowing most racers to convert to DSM technology right away.
• Short 8" receiver antenna is easy to mount
• The soon-to-be-released DSM telemetry module will allow real time monitoring of head temperature, rpm, speed, battery voltage, lap time, etc.
• No maintenance or tuning required (always stays in tune)
• Up to 79 users can simultaneously operate DSM systems 
  

	STEERING TRIM-Who wants a car that doesn't track like it's on rails? With the DX3's digital steering trim, you get it perfect every time. And like all the following features, your setting is memorized every time you turn off your transmitter.
	STATIC BRAKE-Some setups and courses requiring lots of steering will benefit from precisely adjusted static brake at neutral-to enhance weight shift for more "turn-in." Conversely, if your car's steering is aggressive, a few clicks of "creep" will be your ticket to faster laps.

	PANIC BRAKE-When heading into the corners, do you hook from too much panic brake? Relax. A few clicks with a thumb rocker will give you less brake-and more control. Nitro racers on the other hand, can add more brake to offset fade in those long mains.
	STEERING RATE-Let's say your steering rate's set for the tracks tightest turn, but you begin to lose "bite" as the race progresses. No problem. A few blips of added steering-using a thumb rocker-will put you right back in the groove.
