dunno why they'd tell you they can't, they told me they could, then i shipped it in, got a call the day after they received it asking if i wanted long or short levers on the switches (i didn't mention that). the guy explained that any programming i currently had mixed with Aux4 or Aux5 needed to be checked very closely and a few days later i had it back with 2 switches. Aux4 a 2 position for tail hook and Aux5 a 3 position for turbine control.
