Sorry to disappoint guys. ( But I love you anyway Ron
)
Oh and Dunc.. I have been losing my hair since I was 19 so no surprises there mate. Definetly no just for men here, I might give the back to black silicone spray a try. it seems to work a treat for you
No idea right now what happened to be honest. I have narrowed it down to the following.
1) Battery died.... 6 volt 3300 mah Nimh that had been cycled 4 or 5 times from new. Yes I am sad to say there was only one rx battery installed in this model. I have given the going back to basics approach a try recently. One battery and no power boxes and such and it seemed to be working quite well ( Up until last Saturday anyway ) With the advent of Spektrum/ 2.4 I have never had so much trouble free flying and I guess I got complacent...
I have checked the battery back at the workshop ( This did involve pushing one cell that had separated in the crash) And this read 6.5 volts
2) Rx Died. JR 12 ch Rx with two satellites both extended. One to the ejection seat area of the cockpit, and the other to the lower side of the middle fuselage. Yes I was only using one Rx
Same reasons as above really.
I have not had a chance to look into that
I really cant see any other reason. The model was flying at about 3/4 throttle so not overly fast. I was just entering a slow roll so not huge load on servos or airframe, and noting fluttered or departed from the airframe.
Thats about it so far.
Analyze away.

what did the ECU reported?
last shutdown ? or is that vaporised?
as for your reciever setup , i used the same setup on most our models (ar9000)
the 12X works fine with also 2 connected (you still have 3)
was the receiver a JR 12 channel?
we did have a dead receiver 2 weeks ago on our holiday.
on the PCB are 2 diodes that catch powerspikes , 1 was blown off for now apparent reason.
it leaves the power on the system,(including ECU) but it cuts the feed to the processor , and starts blinking. basicly DEAD (no signal to servo , surfaces will move by hand , no "hold" possible)
but it would leave the power on the jetcat and show a signal faillure.
if your last shutdown is a power failure then all power was cut , but can also come due to the crash.
but then interesting is at what rpm that was...
i mean if you had a failsafe your gear would have come also out right?
i tested a few things with Carsten on this , but we culd not figure out the faiilure.
i would be gratefull if you snapped a pic of your receivers guts...
