Okay, setting up my radio. I have a 7CAP. I am now messing with the elevators.
I have a S3151 on each side. I went through the PMix to set up a mix for this. Just
to find out when you use the trim it only trims the master not the slave.

Plus the PMIX when set up per futaba it only moves the horn one way. Obviously
this is NOT the way to do it. So, do I need a reversing y harness? If so I can not
find them on tower. Do I need a 9CAPS? I dont really want to put the money out
for another radio. Would rather buy other planes...help guys!
