DX7 or other 2.4 Ghz for long range E-glider

Has there been enough field testing to determine if any of the 2.4 Ghz radios will have the range to operate an e-powered glider when you get it WAY up and out there? I had no worries on 72 Mhz, but that radio has been sold.
I need to buy a new radio, and before plunking down the $$$ would like some real-world feedback for this application.
Thanks!
Bob

Range should not be a problem with a properly installed Spectrum dsm2 system.
Just pay attention not to install the receiver (with it's short antennas) inside a carbon fibre fuselage. For a wood or glassfibre airframe the range will be further than your eyes can see... (I've read the number 2miles somewhere, but can't confirm that)

I fly DX7 and AR7000 receiver in an electric 100" sailplane and have flown it very high and far away, never had a glitch or problem.
I use AR7000 RX's in all my applications at the moment...And will use it in future sailplanes as well.


If I'd do it again, I'd still go 2.4ghz but choose the JRx9303 raio, it has more sailplane friendly programming and features. I will probably end up selling the DX7 and buy a X9303... The spectrum receivers work with the JR radio because they are both 2.4ghz dsm2 systems.

Note: Futaba use FASST 2.4ghz system and is not compatible with the Spectrum & JR's.

There is a thread in this section on range testing. They got over 1.5 miles ground to ground.

I am flying a Multiplex EZGlider Electric to as far as I can see it with 20/20 vision. I have about 50 flights since Jan 08 using the AR6100e V1.2 receiver and have never had a problem. The RX fits in the Elapor foam cavity where my Electron 6 RX was and it is sometimes covered up by a 4 cell LION pack and still no problems. I've not tested it in any of my fiberglass or carbon fiber fuses yet. The DX7 has a built in mixing program that lowers flaperons or raises spoilerons when you move the throttle stick down to a pre set stick position. I had to put a notch/bump on the throttle stick ratchet but this feature is what I like most about the DX7.

Will the DX7 handle all the sailplane moves you need? Full house/Crow etc. BTW, there are some killer deals on Royal Evo txes right now. And you could XPS or Spektrumize them if 2.4 is your thing.

Here is the range test of 6100 and 7000 by a fellow in Arizona.

Or X9303 which has extensive glider programming.
