"Simply awesome! I'll give it a try as soon as possible, but this definitely worth more testing and getting included in final release. Would it be possible to pass it as a waypoint parameter so we could have mission with both straight lines and…"

"Looks cool! Must be able to act as a follow-me box, but what's the composite video for ? I don't see in-out so it can't be ground osd."

"Greetings to everyone once more! I spent this morning trying to get Crashpilot's RSSI PWM patch (I am using an frsky rx also) to work with latest copter code but no luck. Any plans to add it to the official release some point ? :)"

Dimitri replied to Craig Elder's discussion APM Copter 2.9.1.b has been released
"I think this is incorrect, copper is widely used to EM shielding. A (grounded) film between the PDB and the controller should reduce magnetic interference to the compass coming from PDB/ESCs. Any ferrous material would work though afaik."

Dimitri commented on Mike Machado's blog post Sneak peek at mavboard progress
