    Interior / Exterior

    Excellent paint and interior. 2006
    Painted the belly a metallic gray 2019 to update the design. The all-white base was getting boring.


    I have owned 6Y for 18 years and perfected its flying characteristics. 
    New style wingtips improve the slow flight characteristic- the stall is 5 kts lower at 68 kts with full fuel. Slow flight is stable and the landing touch-downs are softer. With 0 fuel in the wings and 20 gals in the header tank, It stalled at 61-62 kts in the landing configuration. It lands easier than my Mooney Rocket. Just 10 kts faster on approach. 
    It doesn't seem to want to stall w/ gear up and full flaps. I tried several times. 
    89 gals total. 34 ea. wing,  21 gals in the header tank. 
    Fuel burn:
    24.4 GPH @ 10.500'
    23.4 GPH @ 12,500'
    22.3 GPH @ 14,500'
    22.9 GPH @ 15,500'
    21.4 GPH @ 16,500'
    20.6 GPH @ 17,500'
    Trades considered for something with a large cargo door.
