Using an Orange Rx receiver and Spektrum DX6i :
I plugged one aileron servo lead into "AILE" and the other one into "AUX1"
Set WINGTAILMIX to DUALAILE
Flaps to
Flap Elev
Norm 0 0
Land <up> 55 <down> 15
Mix 1
Flap -> Flap ACT
Rate D + 75% Rate U +75%
Switch MIX Trim ACT
And reversed nothing...
This works in three settings:
1 - Flaps = 0 Mix = 0 Normal
2 - Flaps = 1 Mix = 0 Flaps @ 55 % ( down ) Elevator @ 15% ( up )
3 - Flaps = 1 Mix =1 Flaps @ 75% ( down ) Elevator @ 15% ( up )
And this seems to work for me... if you equate to "AILE" to "Ail ch2" and "AUX1" to "Flap ch6"
Then it is pretty much the same idea. The position of the servos makes a difference, or at least
the side of the control used... if you need to "Reverse" anything... I did need to reverse the elevator,
but that is aside from this issue.
I hope this helps?
Didn't do a video... ain't got the time or inclination!
