3gx initialization issue (elevator down)

[lucidchaos]

Out of nowhere, my 450 Pro 3gx tipped hard left on spool up one day. Scraped up blade tips pretty good. Since then, I notice half the time when I fire up the 3gx, after the swash raises and lowers a few times, my elevator servo creeps backwards. This has caused me to replace two pair of blades from when I didn't catch the issue beforehand. When it does initialize properly, it flies great the entire flight. Any ideas on how to fix?

Make sure no trim got entered on any of the FMs and or sub trim got changed somehow.
Creeping like that indicates the unit is sensing input. You can link up and go to movement screen and make sure you have all 0's for cyclci movement with the stick centered
