Getting ready for my first Auto FLight with my 3DR quad.  One question before I go.  I have mission planner up and running and going to make a flight plan before I head out.  When I get out there will the home alt and coordinates lock, Since I can't set those unless I am out there with the computer.

@Andre - I used to put the Yaw D value to 6 before, that gave me a crisper rudder command. Try it, let me know if it has the desired effect.

Which PID value would I adjust to make my quad's rudder input more sensitive?

Ian, I have/had some trouble like this on my Jdrones Hexa... under the "Motors" command, my motors started firing out of order, instead of starting with motor 1 like it should on the hexa in + config... it started with #4 and continued around the loop. I couldn't get help on it yet, but logically, I figured if I move all my ESC jumpers 1 slot ccw, it should line my motors up properly...  it didn't, they moved one more slot further away on cw.... I am going to try and go the other direction now and see what happens tonight.

Ian: See this link: http://code.google.com/p/arducopter/wiki/APM2_Motor_order It is already in the wiki. I am assuming you have an APM2.

Need some x 8 help... Do I use Ardu coptor V2.5.3 octa X firmware?  I have all my motors setup as per wiki X8 counter rotating diagram, but when I run the motors test, it does not conform to the video in the motors test. 

 Motors are absolutely wired correctly, I disconnected and listened for esc beeps to test, and they are correct, what am I doing wrong?  Instead of 1-6 4-7 3-8 2-5 like the video, mine is firing 1-3-8-4-2-6-7-5, I can't find any info on proper firmware setup for this config, any help would be appreciated...

Here is my  configuration with all my current pids.  This is the 3DR quad with 880 motors.  Feel free to let me know if I need to change anything.
