V Speeds
Mike Dwyer
I measured my Q200 at 900lb.
Vs 67 mph
Vx 85 mph
Vy 120 mph
Vne 230 mph
I did find that with the engine at full power the plane would lift off around 60 mph (below stall speed) I think due to the additional airflow over the wing at full power. Due to that I would always lift off and stay in ground effect until 100 mph, then climb out. I would fly final with 2 170 lb people at 90 mph and single place at 85 mph. If you want to land in 1600 feet.Mike Dwyer

Close? And yes I understand that I need to test these and run numbers and graphs later but for now I am trying to get conservative ballpark numbers.
Thanks Robert

Love building planes almost as much as flying. Latest completed build is "Loki", a Chinook Plus 2 bush plane.
Those numbers are likely too low on the low end. Also depends on weight. Typically, the values are determined at gross weight, and using an O200 will raise your empty and likely raise gross as well (you are the manufacturer so your call). My Vs at 1100 pounds is 70 mph, Vx is 88, Vy is 95, Vm is 145 (adopted from the UK type sheet). Your Vc will likely be faster than my Tri-Q2, so no comment. Vne is 200.
