Pushing a Parrot Disco to the limit

Hi guys, Could someone give me advice or help on running Arduplane on the Parrot Disco???
I followed the document on Ardupilot.org but there is not quite enough details for me to make it work. Do I need to kill the DragonStarter process before launching? How to manually start vid_rec before taking off? I have tons of errors in Mission Planner after loading the disco.param file, is this normal? I love this wing and it flies great with an RC remote and the Parrot AutoPilot, but would really like to use ArduPilot and MissionPlanner with the Disco to do some long range missions. I also have a 4G modem working on my Disco, but I just can’t seem to get the basic’s of Arduplane figured out. If someone could help, that would be great!
I can post whatever info is needed. Firmware versions etc. I have telnet access and FTP access to my Disco and can edit and test whatever is needed. Thank you!
