Simon,
use this values for your airframe.
I am not sure about yaw signals.
If you have problem change the signals @ yaw line.
have you assembled you aircraft ? all motors start ?
What kind of esc are you using ? i think you using MK esc right ?

Subject: [Paparazzi-devel] Rotorcraft Mixing Values for an Octocopter
Hi
I am having some trouble working out how calculate the roll/pitch/yaw coefficients for an octocopter. I have been following the
http://paparazzi.enac.fr/wiki/RotorcraftMixing guide but I am not getting it (btw, I think the x,y axis labels in the diagram need to be swapped).
Given that the octo is configured as indicated in the attached image, what values should I be using for the A matrix? All arms are of identical length.
Thanks,
Simon
