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.

Bradley: Are you using the 2.5.3 code? The Alt Hold issue was with 2.5 but should have been resolved with 2.5.3

Comment by Bradley J Carr on March 30, 2012 at 4:09pm

Well I have had the second voyage with my 3DR quad with the 880 motors,  everything worked great.  I still need to try the failsafe but that will come when I get some of the other things tweaked right. 

1.Alt_hold-  it would be about 20 feet in the air and would drop to the ground before it would recover.  Didnt' hit the ground very hard. 

2. Loiter- Same thing as the Alt Hold except the range of it holding at the GPS location it was moving around alot about 20 feet each way. 

It flew like a champ though.  Thank you to everybody that has helped.

First flight today! My home made quad with APM1

Altitude of almost TWO INCHES. I was able to remain in flight for almost FIVE seconds. It was amazing :-)

I need to fix a few things, mount the propellers better and tie down all lose ends.

Soon... flight #2 and pictures or video

Yes, just click the icon in the MP and go through the setup process on the Configuration tab. No need to ever use the CLI.
