Hi there!

I`m trying to build a MAVlink based head tracker TX, because I think the unused RC outputs RC_Out 5-8 and A9 / A10 / A11 would be a cheap and easy option!

What`s missing is a MAVlink command which allows to control the PWM outputs of these channels directly.

What if found so far:

-   The official command library (https://www.google.ch/search?q=mavlink+commands+arducopter+2.5&oq=mavlink+commands&aqs=chrome.0.69i59j69i57j0l3.4424j0j7&sourceid=chrome&espv=210&es_sm=91&ie=UTF-8)

-   The commands of the Camera / RC controll functions of the MP for Android -> They use MAVlink message_ID 70 == the forced  RC_Inputs (not that great, because I`d like to use all input channels...)

- MAVlink message_ID 0x82, set servo 1-7 to PWM. But the documentation seems to be outdated, at least it didn`t work so far (https://code.google.com/p/ardupilot-mega/wiki/Commands)

Any help would be appreciated!

Thanks and merry christmas!
