We have a huge cell array and antenna tower in one corner of the field, and it has long been a suspect (or scapegoat!) for a lot of issues people have had (never with Futaba, though, and so far, never with DSMx.)
Each time we had the issue, we lost all motor RPM, and plane stayed in last flight position (failsafe), with no throttle or elevon control possible.
Upon approaching the crash site minutes later, we now observe elevons back to working and motor now responsive, and even with SOLID led on the receiver!
The solid led was a puzzler, until after today's crash. I turned everything back on at the pits bench, then turned off my transmitter. As in flight, the elevons go unresponsive, throttle goes to zero, and the led goes off. But here is the unexpected part (for me, anyway) -- leaving the battery on the plane plugged in, turning the transmitter back on, once the new bind occurs, we get a SOLID led -- not flashing.
I know Spectrum themselves has a dozen different varieties of these little receivers and some of them flash, some don't, some have two leds, etc. I started to make my own look-up table with descriptions of fade, brownout, frame loss, and what each one did for each type of event - if anything.... but when I saw that DSMx doesn't indicate anything for fades and frame loss, I finally just gave up on the idea.
What I would say is that we won't fly another foamie out there without a satellite, or at least a reciever with antenna diversity, and actually, I would feel even better still going to the new DSMx receiver, since that is true frequency hopping, and spread spectrum.
I have a DX8, and I have the TM1000 telemetry too, so what I thought I might do (but have been too lazy to do so far) is to first learn how to set up the system to indicate signal quality metrics on the screen, then use a plane to basically 'survey' our field by flying in different sections at different heights, and observing the data.
If you notice, I did red/green in the proper aviation orientation (red on left, green on right, when viewed in the sky just remember "red, right, returning"), and then blue/white on the bottom. No issues with orientation at all.
If anything, these lights are a little too bright. I find I can't look directly at the plane for more than a minute or so, then have to kinda look off to the side of it, not directly at it, otherwise my eyes will start to water. Weird, huh?
