How do I translate Futaba Tx settings into Walkera Tx settings

[Keratos]

I wondered whether you could offer advice on how I go about settings the following identified on page 26 of my Align FL760 when using a Futaba Tx. Here is a link to my manual http://www.walkera.com/en1/fileDown....expe.pdf&la=en

Heli Setting	Futaba menu setting
Main blade pitch (collective pitch)	main blade pitch 10deg ~ 12deg with swash pitch 33%~38%	what does this do if my mechanical pitch is -2deg to +10deg
Cyclic pitch AIL/ELE swash	Cyclic pitch 10deg with swash AIL 40% and swash ELE 40%	whats the difference between this and the next row?
AIL and ELE swashplate mixing ratio	Swash AIL <=40% and swash ELE <=40%	? as above
AIL and ELE gyro gain settings	12 o'clock (50%)	I understand this, but the gyro itself has a screw setting that can be set to 12 o'clock (50%) but the Walkera Tx can also assign a 0%-100% value??

I've no idea how to translate the Futaba menu settings into Walkera Devo 10 menu settings , or what some of them do?

thanks (in anticipation)
