I recently had to re-hinge one side of the elevator on my DP Ultimate. When I was finishing up I realized that it appears the only way you can adjust the elevator throws on each side is with the holes on the control horns. For those not familiar, the DP Ultimate uses a single servo with dual wires going to the separate elevator halves. Since i was not the builder, I had not seen this setup before. Am I correct on the only available adjustment, or I am missing something.
