This $200 radio replaces your RC receiver and connects to your RC transmitter. Using the UHF band and higher power than regular RC gear, it's supposed to extend your range to miles. Mostly intended for FPV flying, but has clear application for UAV use, too.
The manual explains how it works:
Basically, any 4-15 channel radio can work with this system, you just need to find
the PPM signal from the radio.
We can get the PPM signal from the trainer ports for Futaba （ Non-JR ） series
radios. Because the trainer port of JR just output 4-chans PPM signal, so we need to
find the PPM o utput from other places, normally we can get the PPM signal from the
pins of the RF connector.
You can get all the definitions of the trainer port for most of the popular radios
here.
.
For the radios which have removable RF modules, we can get the PPM signal
from the pin of the RF connector

Ok, yes, polititians need topics to divert attention as does the press.
So the least we can do is to fly with reasonable safety in place. Even if the law and FAA would allow more!
Duane, thanks for that clarification. I was not talking about commercial, thats definetely another ruleset...
The use of observers actually is a (human) sense and avoid system. And humans are the only system accapted at the moment (regardles if recreational/commercial, manned/unmaned).
But then every observer gets a RC transmitter and you don´t need high power...
My concern is just that the systems in question lead to stunts like the one in NYC... Which I think we agree was not good for the hobby...
Duane, in my opinion, going on 27.255 is not enough safe, because it's fixed frequency. Any interference sent on this frequency will hit the plane. Much better to use FHSS (Frequency-hopping spread spectrum), which changes its frequency many times among the band.
Such systems as Dragon Link, Scherrer UHF use as far as I know 433-444 MHz band. It's much more safety. It's possible to fly 15-20 miles and farther with this systems.
As for this RC Kit, it looks like Dragon Link, however, the price is twice lower. Nevertheless, who knows, maybe the quality is twice lower too?!
Long range ground control can be provided by this system.
0 feet AGL is an area of operations free from the usual concerns.
27 and 433Mhz are great in urban environments, reduced reflections, less like a beam of light.
Hi Duane,
interesting, and how do you guarantee "Sense and avoid" ??
Hi,
regarding all the long range systems coming up now I´m wondering if it´s really legal to operate them under HAM license. For germany, I know for sure it´s not (I got my license some years ago and of course checked if it would be useful for FPV video and/or control). In general amateur radio is meant to get in contact with other people and/or do experiments, which both is not the case for these systems. If the laws allow you to use it, you are lucky, of course. But be aware that there can be amateur transmitters on that band running several 100W of power plus antenna gain...
Anyway I don´t understand why you should need such a system (apart from the price :-) for doing legal UAS/FPV activities, as these have to be performed LOS! Any good 2.4GHz RC-System will give you good results in this range.
So if you have to use a high power system you eather got interferences (which you should get rid of (better design)) or you want to fly fa away... which you "should" not do.
So, why is this of so much interest?
