as it was kind o difficult to me setting up flight modes on APM the way Gordon discribed,  I tried to find an easyer way (but still Gordon did a good job and my way based on his...)

Big THX to apocolipse, as I forgot to write which firmware I`m using. It`s the er9x (lates trunk)

I show on an examples, as it is real easy. What I did is to use the custom switches 1 to 6 (csw1 - csw6) and the mixers.

Goto to mixer and add a line  with the setting (in my case ch8 but it`s up to u, which ch u use)

CH08    100%    MAX   SWITCH    (SW1)

            100%    MAX   SWITCH    (SW2)

            100%    MAX   SWITCH    (SW3)

            100%    MAX   SWITCH    (SW4)

and so on....

Ok, now I go to Switches an assign the following values  to SW1:

CSW1 function: and   /  value1:ID0   /  value2: !AIL (if u`re not use to,  ! means not active)

CSW2 function: and   /  value1:ID1   /  value2: !AIL

CSW3 function: and   /  value1:ID2   /  value2: !AIL

CSW4 function: and   /  value1:ID0   /  value2: AIL

CSW4 function: and   /  value1:ID1   /  value2: AIL

CSW4 function: and   /  value1:ID2   /  value2: AIL

Now you hook up APM in cli mode, going to pwm test. Taking the radio and adjusting the 100% value on SW1 so, that I get the recommended 1165 for normal mode (in my case: CH08   /   -65%   /   MAX  /   SWITCH(SW1).

Do this to all mixers.

Then I set the modes, like shown on diy google codepage.

That`s it.
