I am new to this radio even though it is old and this thing makes me feel like a box of rocks. I have a plane with two separate servos for the flaps. I know that ch6 is for flaps and when I pull the switch "E" it works for one servo plugged into ch6 in the receiver. I want to move Flaps from the switch "E" to work on on slider on right side of radio "VR E". My second servo is plugged into ch7. What do I need to do step by step, PLEASE, to set this up.

Thank you
