Paul........There is a mix called ele to flap. It works with 5&6 but........
You can only go flap or spoilerons. I tried to set mine up so my 3 pos switch would do both. top is flap and bottom is spoil. but for some reason when i make a mix to do it, it doest work. it works with the 6&7 but not the 5&6.

If you have any ? feel free to contact me.
