Musketeer
A stable practical, 100 kts, 550 NM, 2 seater aircraft.
3 to 4 seater with a reduced fuel load. (Like most small airplanes.)
Lower altitudes 95-100 Kts IAS and 100-105 Kts True at 1O GPH.
Higher , FL 65 - 75 you might get 95-100 IAS and 105-110 true airspeed, but it climbs like a brick, and a fuel flow of 8.5 to 9GPH at 75% (Wide open throttle and leaned) in the F-Levels.
8OO NM? No way, unless you want to glide the last part into your destination. NO - LOL.
