DOA, I got between 7-9 glide ratios. Are you feathering the prop? Use the keypad_minus key.
Niklas,
I will use 370 mph, 2000 hp, 80% efficiency and 7400 lbs to figure the drag coefficient. Wing area is 173 sq ft.
1620 lbs thrust
Cd0 = 0.0259
Cdi = 0.0008
For glide, Cdi = Cd0 = 0.0259
If Cdi = Cl^2 / (pi * aspect ratio), then
Cl = sqrt(Cdi * pi * aspect ratio)
Cl = 0.70 (aspect ratio = 6.1)
Then V = 155 mph to produce 7400 lbs of lift
Drag force ~ 551 lbs
Lift/Drag = 7400 / 551 = 13.4
It could be that thrust values in the sim are on the high side, necessitating higher drag to keep top speed and climb in check, but adversely affecting glide.
