    David,

    a few things to add to this...

    1)  FrSky has now announced that they will be selling an 868/915mhz transmitter module and receiver for LRS...  using the FrSky protocols, which allows for 16 channels, telemetry, and specific model ID.  (RX will refuse to do anything if you have the wrong model selected on your transmitter)  It has no ETA yet, but will be called the r9m (tx module) and r9 (receiver).

    this will be using 868mhz for europe, 915mhz for USA/Canada...   you will have to look and see if 868mhz is allowed in GB.

    2) the ChipLRS parts have an advantage for the europeans.. 1) it is made by a guy in russia, so shipping is quicker/cheaper than from china.  2) his prices are reasonably cheap, $20 for a receiver, $65 for a TX/RX combo, not as cheap as OrangeRX, but cheaper than hawkeye.  all of his equipment works with my ersky9x/openTX firmware based transmitters, so soldering a 3 pin connector to the receiver allows me to get full telemetry on the built in LCD display on the transmitter (and voice alerts based on telemetry triggers as well)  even ordering his stuff off ebay, it arrives within 10 days, which is faster than the chinese.

    3) you can order from the russian group with any of three frequency choices:  433/458mhz, 868mhz, or 915mhz...  so even if you stay with the 458mhz, ChipLRS might be an option for you.

    4) i have ordered a set of Nagoya 915mhz antennas for both the TX and the RX, these should show an improvement over the stock crappy antennas that all these things ship with off the shelf.
