I had a crash this summer with an electric powered aircraft equipped with a CB200, a REX6A and RSat: while performing rolls, the aircraft continued to roll when I decided to put the wings level. The failsafe did not work either (motor still running). I spent quite a lot of time trying to find the reason (unfortunately, the log was not active) and I couldn't find any fault - except that sometimes, when I powered the aircraft ON, I had a "Signal Loss" warning.
HOWEVER, I have another aircraft not yet complete with the same configuration and new equipment (so it never flew).
Here is the configuration:

I had the same problem and after numerous tests, I reset all the equipment to factory default and downloaded the lastest firmwares.
CB200 V1.31
REX6A V1.12
RSat2 V3.25
The problem remained: I often have a warning at power on (this time "Weak Signal" with the V1.31 version of the CB200).
Also, sometimes, the REX6A does not "Arm" although it works. Instead of hearing "Initialized" and "Armed", I only hear "Initialized."
I only have such problems when a CB200 and a REX6A are used together.
A classic receiver with a CB200 is OK.
A REX6A alone is OK.
So, there is a communication problem between the CB200 and Assist receivers that can probably lead to a crash.
Or, there is something wrong with my setup (see the screenshots).
Best regards,
