RV Jet crash using 3.8.2

Had a pretty serious incident with my mapping aircraft. I’ve built more than 10 identical aircraft previously and never experienced an incident like this. The fuselage was badly damaged, but all equipment survived intact. From the log it looks to me like servo failure, but bench testing at home afterwards, everything seems to be working fine! Would really appreciate some help with the log to see if I’m missing something. Aircraft is an RV Jet using Plane 3.8.2 and the Cube as FC. Log attached

Edit: can’t seem to upload the log for some reason - Please PM me or have a look on the facebook page
