I read in the description of the ardupilot board about a "hardware-based" failsafe. I also see the SW in the AP repository. But nowhere I find a word about uploading the code to the AP. Is the board already preloaded? How can check is the FS is already loaded? How to load the FS?Researching for integration of the Remzibi OSD into the AP I am stuck. Is there anybody out there who managed use (and share the GPS of the AP ) the AP downlink for transmitting video stream. The capacity of the XBee 900 should be big enough for that.All hints are highly apprecïated.Merry X-masChristof

Christof,
I don't think the xbee is wide band enough and so would not suit video txing, the point of Ramzibi integration was to share the GPS alone so that you don't have to duplicate GPS on-board
The FS code is pre-loaded at the factory. We purposely black-boxed it, so people wouldn't be tempted to mess with it, but if you want to change it you can with an AVR programmer (AVRISPII) via the board's ISCP connector ("Attiny")
Many people have tried to do video over Xbee, none with any success that I know of. Once you account for handshaking and duplex, you don't have enough bandwidth.
