Default Climb and Hub setting

No, Steve, that 68mph at 5,050 is not the max available or full effort. It is a data point to determine hub adjustment recommended by Roger Lee of the Tucson Rotax Service Center....different rates of climb will produce different rpm max figures. They recommend testing performance by setting the rate of climb at 68mph and then insure that you have at least 5,000 rpm. Other than that there is no significance to that rpm figure. The second check data point they recommend is WOT in level cruise at what ever altitude you usually fly to insure that you can get 5500.
