I'm about to put the finishing touches on my Top Flite 60 P51D. I have a bit of a dilema though and need some help.

I have two servos controlling the ailerons and two controlling the flaps. Here is what I'm thinking as far as programming my 9C. Should I 'Y' the ailerons together and 'Y' the flaps together? Ailerons on channel 1 and flaps on channel 6? I'd like to assigned the flaps to either a 3 position switch as to have flaps up, half flaps and full flaps or to a slider switch on the side of the tx.

Thoughts?? Thanks,,
