Someone correct me if I'm wrong here but I beleive the elevator and flaps will require the much more expensive reversing Y harness to operate correctly. If you have the 7th channel I would recomend NOT Y-ing the elevator so you can trim each elevator half seperately and get them perfect. Any roll tendancy from applying up elevator on this plane could be the death of it at slow speeds... Like landing[:@]

I have a FuntanaX 100 but only have a 6 channel TX so I had to use the reversing Y on my elevator and mechanically adjust it. It works well but the manufacturer does not recomend this. They recomend a 7 channel computerized system.
