Thanks for posting this Tridge.
On the copter side, I wanted to point out the slide on the upcoming start of beta testing for AC3.5. We've got a few more PRs to get into master but we're still hoping to start beta testing within 1 or 2 weeks.
The AP_Sync project is also introduced. Peter Barker or I will do a blog post on that once we have our first images ready for people to use.
