This is good stuff, guys, and I really appreciate it. Allan, I will take a close look at your setup because I am using the DX7 for the Seagull.

Ken, that differential in the geometry is what I was concerned about. Especially noting that a very small change in the elevator causes a visible change in the flight path of the aircraft in flight. So, if one side deflects more than the other side, then the result is obvious.. the plane will probably veer to one side or the other, undesirable for input to elevator caused reaction.

One gentleman sent me a pair of small lasers to use as alignment tools. They take a 4.8 volt NiCd battery and put out a focused beam that can be directed to a ruled scale. I am going to use it to check deflection of control surfaces. I can tell what is going on with the alignment and movement of the ailerons, elevators (both sides) and the rudder. Neat gadget for centering and measuring throw.

DaRock, I currently have a wired Y reverser installed. I am going to play with that just to see how much, if any, differences exist.. then I am going to use the computer radio, as Allan suggests, to get them right.

Thanks again, guys.

Dick.
