Excellent well you know what they say 'third time arounds a charm' . Only thing is converting a stick from a tri-gear to a tail dragger is not really a "Sex Change" its more just an 'Attitude Adjustment"

I have never used a cheap single servo inline reverser so cannot comment but have used a reversing "Y" cord on a two servo split elevator installation. And while I cannot claim it failed it did cause some flutter that I was not happy with so my solution was to do some surgery to move the servo about an inch or so the two servos for split elevators could work properly with an ordinary "Y" cord.
