I'm trying to dial in a dual elevator setup on my Funtana 90 with a 7CAP and really just don't know where to start. I know I have to use one (maybe 2?) of the 3 available mixes, but nothing I try seems to work quite right. Trying to search for help but nothing yet. Any advice? Or will I just have to settle for a Y harness (or Y-reversing harness)? Thanks.
