DP Edge - Problem with Pull Pull Elevator
 

I am putting together the DP edge 540 and I am using the pull pull system on the elevators. I noticed that both elevators are even when neutral, but when they move up or down one lead and the other lags.

The manual has you offset the control horns on the elevators and offset the servo for the elevator to the right when looking at the plane from the tail.

Can anyone tell me how they set theirs up and if they had the same problem?

Thanks
Erick
