I seem to remember that one of the elevator servos is offset slightly above the H/stab and the other on slightly below. This makes a reverser unnecessary. I do not remember any installation difficulties so it must have been quite straightforward...
Not true. Both servos are below the stab with the horns on top, thus making it necessary to use a reverser unless you have a radio that allows for separate elevator servo connections in the receiver.
