V977 = V931 ? Collective Pitch ?

Hi !
Though my (adapted ?) ini seems to work fine (the AS-350 flies not bad) I am absolutely confused.
Where is the Collective Pitch channel ? What does channels 6-8 do ? ( 8 seems to switch between 3 and 6 axis - I use a Devo 7 with the switches mod).
User Babay talks about a Pitch Trim - Post #28732 . What's that ?
I also have absolutely no idea how the pitch management does work with this heli.
I have added the ini-file I recently do use.
Every advice is highly appreciated.

Update :
In the meantime I followed user ahmadie's advice and visited the page referring to his post here . Downloaded both firmware and ini from this russian site.
I now too have 11 channels on my Devo7e and the AS-350 heli flies nicely especially in 6axis mode, which fits perfect this little scale chopper.
So far so good.
I still would like to know how the pitch is managed with the V931 model. Obviously hard wired internally, I suppose.
Let's see how pitch trim works referring to Babay's post here .
