After having had a Talon sitting my garage for almost a year, I finally got around to building it. The instructions were poor, but the build was easy, so it didn't matter:
After a trip, I spent some time to put my FPV gear in because I wanted my next videos to have telemetry showing airspeed and other options on the video so that I could review it more easily and check minimal speed with and without flaps, and see how things go before stalls
I figured I'd cram the $500 gopro inside the CXN mount so that it would be less exposed in case of a crash, and the FPV camera goes on top:
I only had enough time to pull on the elevator but not enough to retract the flaps. Replaying the video shows (with only a few pixels) that one of my ruddervator surfaces got unglued due to the G and weight stress, causing a full loss of control and full speed crash into the ground :(
The impact was severe enough pretty much everything was broken, including both microsd cards that were in the cameras:
Obviously, this was very disappointing, although I leanred a few things:flaperons on the X-UAV Talon are very dicy because they almost work as reverse elevator :(
you need to very heavily glue the ruddervator surfaces, and I failed to do that. Expensive lesson...
turns out I wouldn't be using the dome, like most people
my wing extension kit came with this seemingly useless replacement gear that weighed way too much
sadly, the wood support didn't have any underneath plate to put the autopilot on
so I had to make my own plate to attach to the supports
I got to fit my pitot tube between the main wing and the extension
didn't bother putting the dome

I added some wood so that it would hit first instead of the cameras :)

first card has an internal short and won't work and 2nd card was sliced by the shock :(
the lipos also didn't like the Gs, but thankfully did not burst into flames
