Closer to home; Steve, I used to run a Multiplex Funjet into the stratosphere with stupid big motor and battery and never had any radio issues.
I DID however have a FRSky 6ch rx which has nice long antenna wires that allowed me to route one antenna down a groove on the wing and another to the nose and have a nice 90deg diversity setup. Never heard a peep out of the RSSI Telemetry...
Spektrum's weakness is/was that they have short little antennas that don't allow you to do this without running a satellite Rx. Seems their newer Rx's come with longer wires.
Just for those that that don't know, RSSI stands for recieved signal strength indicator. With FRSky recievers that support Telemetry, part of the signal that comes back to the TX contains information about the strength of the signal that the RX is picking up. If the signal strength falls below a certain threshold then you get an audible warning the your transmitter. Very handy !!
FRSky telemetry RX's also have an inbuilt A to D converter that allows you to monitor things on the plane while it's in flight. I use it to monitor my Lipo voltage, there is a two stage audable alert you can set at any two voltages you like. In my case the first warning lets me know the lipos are getting low and the second more urgent warning tells me they are just about to die.
I really think that with bigger, more powerfull planes you really need to have some extra safety features, like the sort of things FRSky offers.
Eventually it will save, the cost of a plane or more.
