I'm with WilsonFlyer on this one.

While I'm no radio expert, my experience with things radio indicate that the higher you go in the frequency spectrum, the more limited some functionality becomes.

i.e. my 2.4 GHz cordless phones don't have nearly the range or clarity of my old 900 MHz phone. The 800 MHz communication radios the Fire Department I worked for didn't have even a fraction of the range of the old VHF radios they replaced and were extremely susceptible to being blocked by physical objects. Now one might think that's not a problem as one should maintain line of sight visibility with an RC model, but it speaks to me of glitches.

Then you look at the antenna situation with these and two rx's? Two rx's and the antennas need to be placed at 90 degrees to each other for best results? They say the second rx is to assure better signal reception?

Like electric power things will probably be headed this way for the reasons noted, but new stuff particularly in consumer electronics is usually put out with an idea of being first, not being bug free...

I've got too much money invested in my models to be an early adopter on this RC radio technology...
