Not to discount what dgrant said. But I have owned three of the reverse Y's and one of them worked right. The other two would change trim in flight. Kind of a pain to land a plane when one elev half is tilted 10 degrees. Maybe mine were out of a bad batch, many guys have great luck with them. However if your radio will mix it in, that is the best way to do it. If the mix is set up correctly there should not be a delay. On the 9C I use channel 5 and have it on 6 planes that way. Never an issue.
