I have a dx8 with a AR8000 reciever and I am trying to setup flaps and gear but can't get it to work. I have cessna that has two servos for ailerons with a y connector and the same for the flaps and I would like to use the gear channel for a drop box. What do I need to do to get the flaps to work. I have played with the swith settings and port I plug the flaps into but nothing. ANy help?
