New plug-in 2.4GHz modules!
Let the 2.4GHZ wars begin!

Xtremepowersystems

***NOTE*** I am in no way affiliated with this company; I just wanted to let everyone know the technology is maturing, as many are interested in migrating to this band.***

Also, this this is a BI-DIRECTION system, and will be able to support telemetry from the model as well!
XtremeLink™ Features:

Range

Up to 1 mile (5200+ feet) ground based, line of sight.
Up to 5 miles (26,000+ feet) ground to air, line of sight.
Frequency

2.4GHz ISM bands, using real-time frequency hopping on all available bands.
Spherical RF radiation technology eliminates the need for multiple antennas.
Resolution

12 bits per channel (4096 system).
+/- 10ns servo pulse accuracy.
Interference

1 in 18,446,744,073,709,552,000 chance of being on the same channel as another module.
Up to 390,000 active modules in use simultaneously.
Antenna length

1.2" for both receiver and transmitter, fully enclosed.
Miscellaneous

Programmable failsafe for all channels (in event of transmitter battery failure).
Programmable channel mixing, swapping, and duplicating.
Bi-directional telemetry data interface.
FCC, IC, and ETSI approved.
Specifications:

8 channel receiver -
Dimensions: 2.115" x 1.125" x .525"
Weight: 19.15 grams (.675 oz)
Input voltage: 3.5v to 16.0v
10 channel receiver -

Dimensions: 2.115" x 1.315" x .525"
Weight: 21.50 grams (.758 oz)
Input voltage: 3.5v to 16.0v
Telemetry modules -
Dimensions: 1.25" x 1.05" x .45"
Weight: variable
Output voltage: receiver battery voltage


An 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.

nice proboscis.

i wonder how exposed that thing needs to be. it seems to replace the 'string' antenna. does their definition of 'line of sight' mean not under a canopy?
if it ain't broke, break it.

Do you use the radio in PPM mode or PCM mode? I would imagine that you need to switch to PPM mode... and then your ability to set a failsafe from within the radio goes away.

But this looks freaking cool. I'd give it a try. ...If it ever comes out.

Haveing read the info on the website, my interest is peaked a little more. I really like the idea of 4096 resolution. This type of product would make IRCHA alot easier to deal with as well. Up to 390,000 pilots at once? Starting to sound pretty good...

How much, when and what about 35MHz sets, is it truely plug and play or do they have to make changes for non-US tranmitters to work with it.

It replaces the frequency module so it is universal.

I can't wait. I'll test it on something I don't care about (I have a 4-star 60 that I have $14 into that would fit the bill nicely) before it goes into something valuable, but god that looks promising.Nick Crego

I was thinking the same thing. I have an Avistar and a 9C that would be a decent test platform for this.

Definitely a good solution for IRCHA and any other fun fly for that matter...

Who's behind the company? Its located in Arizona and is very vague about most things except the legal page!

They patented blinking apparently

I'd like to see if AMA/FCC approves 3rd party modules on our radios. Since they approved the Spectrum hack on the JR radios, I would thing that opened up the door to allow these.

Someone said there was a price listed at $189, but I didn't see it.

Mike...

MSRP for the "flight pack" will be $179. This includes your choice of transmitter module (JR, Futaba, or Hitec) and one 8 channel receiver. MSRP for the 8 channel receiver will be $99. MSRP for the 10 channel receiver will be $119, and MSRP for the 16 channel receiver will be $149. MSRP for the telemetry system will be $129. Additional sensors will vary in price, depending on what they are.
in response to queries about a removeable, remote antenna...
The antenna and circuit board create the actual antenna. If you change the angle of the antenna in relation to the circuit board, the range changes as does the spherical pattern. By having the antenna exactly perpendicular to the circuit board, you get a nearly perfect sphere and the longest range. A sphere is a "ball". It doesn't matter what orientation the receiver is in relation to the transmitter. The "balls" will overlap, and communicate properly. When you don't have the overlapping radio waves, you don't have communication.

There is no way with the current design to make the antenna thinner or make it detachable. We really need the antenna to be stationary, and perpendicular to the circuit board. This is how we get away with using on a single antenna, and getting up to 5 miles of range. We know that there will be applications that this setup simply will not fit in. This system was designed for us guys that have $10,000 or more invested in a plane and don't want to lose it, and for the ability to get real time data back from the plane.
The failsafe is programmed on each individual receiver.
the discussion is by the CEO of the company, JimDrew, and can be found on rcgroups

I would wait to see what pans out. This is the first, real salvo in the 2.4GHZ war. (Spectrum doesn't count, since it's a parkflyer only system) Soon, Hitec's module system will be released, and whle I haven't heard ANYTHING about a Futaba product, it can't be far behind. However, seeing how Futaba doesn't support legacy radios but makes a "Super" version instead, I'm not hopeful that they will provide a way to retrofit their current radios.

I hope they intend on making more than an 8 channel receiver.

Sounds good for AP stuff!
