Hi Meesh,
The easiest way to do this would be to make Flaperons active, then go into Flap mix, set your percentage to how much flap movement you want. Next go into AUX channel and assign channel 6 to a different switch say switch A. Now you should get aileron movement from your stick and Flaps will work from whichever switch you have chosen.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
