What weight? What balance position, how much elevator movement?
The Diablo does not need to land nose high, it is light and has huge inlet/flap drag. If you chop the power before touch down on a day with any head wind it will stop flying really quickly. Many of my customers find it better when we reduce the elevator travel at full flap for landing to 20mm maximum. Expo should also be lower to give a more linear feel on the elevator.
