Regarding that line hold algorithm; You should note the way I'm handling coordinates in my code.. The output is the desired heading. Other than that I don't have the time to explain it more as I'm reading to my entrance exams for medicine.

No that's not a typo. It's used to test whether we move "on the y-axis".

It's the coefficient to determine how agressively we want to "hold the line". It's commented only because you really don't want to copy-paste it to your navigation function but rather to somewhere else..

Autopilot Development Current Status: Information gathering.....

Hello David,

Are you from Malaysia? It good to see fellow malaysian starting to involve in UAV project. :) . I just started my phd right now at University of canterbury, NZ. So I didn't started anything just yet, I just have some matlab code that describe the helicopter dynamics and planning to used optic flow for the helicopter guidance and obstacle avoidance strategies.

Btw, I see that FMA sensor did not provive heading angle info.... hmm, maybe I need to intergrate some gyro/magnetometer instead.

Hello David,
Looks like you are currently the only customer posting that he is having successful flights with the recommended Ardupilot plane, hardware and software. Did you make any changes to the latest code? It seems no one else can get it to work.
