They seem to be, the FC bord standoffs all broke (nylon) but the boards look perfect and even the fragile GPS module looks perfect, I'm glad I intentionally only used one very thin zip tie to act as a break away. I'm yet to try them all out though.
I need a stronger dome than a CD caddy next time, it was useless.
Funny that I had already ordered an x468 frame and a load of bits for a rebuild just days before. Just wish the postie would hurry up now...
Lucky escape for the electronics to survive. Droidworx make a carbon fibre sheild as such to go over the top of the dome on thier SJ6's & SJ8's, you could get them to fit over yours!
