I had carried out some flights earlier on in the day, with no trouble. On my next flight, I got airborne and as I rolled inverted, I lost all control of the plane. The controls remained in their current position and the aircraft went in.
I got no signal loss warning on the DS16.

After grabbing the aircraft from the bush, the electronics were all unscathed. Everything was connected as it should. I took it back to the flightline to try and diagnose the problem, but I couldn't find anything wrong at all.
I have the aircraft set up using dual batteries, fed directly to the CB200. I have 2x R7 receivers connected to the CB200. I have since taken all the gear out of the plane, as there was too much damage to the fuse/wings/rudder etc to fix,, but I have tried getting it to fail again, but all appears normal.

One thing I did notice that day. I have used the teacher/student mode before without any dramas. On the day of the accident, I couldn't get the teacher/student mode to work at all. My friends DS16 wouldn't chat with mine.
I gave up after a while and reselected the dual path. Then the accident happened. Coincidence? But the problem now is..... i'm really worried about this happening again. We all spend a lot of time and money building these planes and one of the main reasons I bought the Jeti system is for the reliability of the 4 antenna's. But this proved to be no safer in this instance than my old JR 9X. My friend who was flying his F22 on the same system, similar setup (dual batteries/rx's) refused to fly it until we could work out what was wrong.

When I turn my system on, everything works normally. If I go into the device explorer and select any of the RX's, it tells me to update to 3.20 firmware. I currently have 3.14 in the RX's and 3.00 in the TX. So again, was this incident because of the 2 RX's not having the latest firmware?? It's quite worrying. Any information on this would be greatly appreciated. I have contacted Jeti, but I haven't received a reply as of yet.
Fly safe,
Mort
