Hi all

We on Sunday my beloved Boomerang nano came to grief and is now balsa popcorn. I wanted to post the details of the crash on here to see if anyone might be able to help in diganosing. My gear is as follows

1. JR9X (X9303) 2.4 TX
2. Spektrum AR7200 RX
3. Turnigy powerboard
4. 2cell Lipo RX batt (regulated by powerboard)
5. Jetcat p60
6. High end metal geared servos

Ok, so I was flying the downward leg in a flat level position when suddenly there was a right aileron command given somehow and the Boomer rolled to the right and into a nosedown dive. By some serious luck as the Nano hit nose first and the turbine let go from the bracket an landed in a long patch of soft grass and is completely intact. All electronics bar the I/O board are fine. The fuel tank seem to shoot out one way and the turbine the other so no fires or electonics damage we can see so far.

The weird thing during the flight that happened was that the elevator trim was out by almost 10 clicks (it had been set perfect the day before in the same conditions). In know that radio had bound properly as I has checked all lights were solid (the flight the day before I had noticed the satellite light blinking so re bound). It was also on the right model and no radio settings were touched . I am yet to check the failsafe settings but I would have expected that if it was a lockout it would not have rolled. Further, the battery was fully charged and seems fine.

My thoughts so far:

1. I noticed the right hand aux 3 slide lever is activated on Aux 3 (which means I could have bumped it). I need to check tonight but I would not expect that to affect the ele or aileron as I was only using a 7 ch RX with aileron on a Y lead on the Aileron channel;

2. the turningy powerboard has somehow developed a fault and is sending stray signals

3. there is something up with the TX or RX

Ideas of what to check are welcome

Cheers
