Xtreme Link XPS products don't seem to enjoy universal praise. I only know one pilot who bought the XPS system for his Hitec Optic 6 radio system; to XPS' credit, he doesn't crash any more at 2.4Ghz than he did at 72mhz. Besides, at $189.99 starting price for aircraft modules and receivers, they're as much as an entire replacement radio system. I bought the Airtronics RDS8000 2.4Ghz FHSS radio system for $194.99 delivered from Tower Hobby.

I have a Futaba 4YBF and a Futaba 7CAF transmitter that I've been flying with. I have no upgrade path with my 72mhz transmitters, and all of the 2.4Ghz systems are proprietary anyway, so there isn't even much incentive to stick with my current manufacturer of choice.

I went ahead and purchased the Airtronics RDS8000 radio system as my platform of choice for spread spectrum. I'm completely happy with my 72Mhz gear, and frequency conflicts are getting much more rare as everyone else upgrades to 2.4Ghz radio systems. I had simply filled up the 10-model memory in my 7C, so I decided it was time to buy a second computer radio.

Xtreme Link XPS has some interesting ideas, and I wish them luck with their continuing marketing and product development efforts. If they can bring a 900Mhz spread spectrum radio system to the European Union market, they may yet have the last laugh.
