I no longer have the files where I was trying to do it so I just quickly tried 
binding the aileron control input to the flaps and got a different result to 
what I was expecting.  As I remember it, when I tried to do this before the 
left (I think) flap would operate as normal through it's +ve range but not 
through the -ve range i.e. it wouldn't rotate up, and the right flap wouldn't 
move at all - this was with split=true on the control-input.

When I just tried it now, both flaps moved through the full -ve to +ve range, 
but both moved in the same direction and the split tag seemed to be ignored.

I'm confused now:)
