XtremeLink™ 2.4GHz combo package.

Consisting of one XtremeLink™ 2.4GHz transmitter module for JR radios, and one XtremeLink™ 2.4GHz 10 channel receiver.

Don't buy another transmitter! Use your existing one!

Imagine a radio system with no frequency conflicts ever. Imagine never having to wait for your frequency pin. Imagine having complete control well beyond the range of what you can see, even with binoculars! Imagine having the ability to get real-time data back from your plane, car, or boat. Imagine control so smooth, that not even top of the range radio systems can match it. Imagine no more! The XtremeLink™ system gives you all of this, and much more... and without having to change transmitters!

The XtremeLink™ is a module system for most Futaba, JR, Hitec, Multiplex, and Airtronics radio systems that have a removable RF module. The system includes a replacement transmitter module that plugs into the RF module location of your existing transmitter, and a XtremeLink™ receiver. Receivers are available in 8 channel and 10 channel versions (a 6 channel lightweight "park flyer", 12 channel, and 16 channel versions will be available in the future). In just seconds, you can convert your existing 72Mhz system into an XtremeLink™ system! The switch is completely transparent to the user. Nothing changes with your transmitter settings. Just remove your existing transmitter RF module (and stock antenna) and plug in the XtremeLink™ transmitter module. Then swap your 72Mhz receiver with the XtremeLink™ receiver and you're done! It's just plug and play! Advanced features include the ability to program a failsafe position for each individual channel in case of a catastrophic failure (such as a transmitter battery failure), as well as swapping and duplicating channels.

The XtremeLink™ system operates on the 2.4GHz band. This is a license-free band used typically for wireless networks, cordless telephones, and other devices. The radio portion of the XtremeLink™ system was developed for us by the leader in wireless network technology. The XtremeLink's™ proprietary spherical RF radiation pattern eliminates the need for multiple receiver antennas. The XtremeLink™ uses all of the available frequencies in the ISM band through an advanced patent-pending frequency hopping technique. The output power is adjustable from 10mw (legal anywhere in the world that allows 2.4GHz) up to 100mw of power (U.S. and select other countries only). Power consumption is extremely low. Even at the highest power level, the power consumption of the radio module is less than 90ma, giving you up to 5 times the battery life over a traditional 72Mhz RF output.

The XtremeLink™ uses bi-directional communication between the transmitter module and the receiver. Data is transferred and acknowledged, both directions. Data encryption and 64 bit CRC error checking means that invalid data being passed to the servos is virtually impossible.

1024 systems are great. 2048 (Futaba's 14MZ) is even better. The XtremeLink™ has an unparalleled 65536 (16 bits) system! Future versions of the XtremeLink™ could have enough bandwidth for live video and audio transmissions!

The transmitter module has a port for a remotely mounted telemetry control unit consisting of a large (20 character x 4 lines) trans-reflective and backlit LCD screen with three function buttons. The unit conveniently mounts in your old antenna hole! On-board sensor modules (which plug into the XtremeLink™ receiver) allow data from your R/C plane, car, or boat to be viewed in real-time! Up to 256 different sensor modules can be connected and accessed at the same time via the telemetry system. The telemetry upgrade comes with the standard flight sensor package which provides battery voltage, on-board temperature, and altitude. Additional sensor modules for airspeed, various temperature readings (exhaust gas temperature, battery temperature, etc.), and many other functions will be available. An earphone jack is used to access the built-in audio output. The telemetry control unit can be programmed to sound an alarm by using tones and/or human speech when certain events occur (such as too slow of air speed, too low of altitude, low battery, etc). Some of sample words in module vocabulary include: altitude, warning, landing, gear, speed, failure.

Many questions have been asked about using a single antenna design versus a multiple antenna design. The spherical radiation technology we use eliminates the need for multiple receiver antennas. However, to please the skeptics, we now have the ability to make one of the telemetry sensors a remotely located receiver. So, you could have up to 256 extra receivers in your plane! Our demonstrations have proven the reliability of the system with a single receiver antenna, but we will be happy to sell you as many of something you don't need as we can!

Interesting Fact!
Digital servos do not "hum" by nature. With our system, they make no noise while idle unless there is a load on the control arm. The reason why other radios systems cause these types of servos to hum is the pulse conversion stability. "Normal" (non-digital) servos do not respond unless there is at least 3us (three microseconds) of change in the servo pulse width. This "slop" of 3us is very common in standard radio systems. Digital servos are so accurate that they respond to as little as a 1us change in the servo pulse width. This means that a standard radio system is causing a digital servo to move around constantly while just sitting still in what is considered to be an idle position. Our radio system has a servo pulse width variation of +/-10ns.
