I need a v-n Diagram for this airplane:
Stall Speed Clean= 200 KM/H
Equivalent Max Level Speed 930 KM/H
Altitude: Sea Level and 40,000 ft
W Gross : 420 Kg
Sw = 2.5 M^2
MAC wing: 0.891 m
CN max + =1.53
CN max - = -1.45
CL alpha= 4.13 (1/rad)
VC Max=926 km/h
VD Max=1300 km/h
Delta Elevator= -14:14 deg
CL max + = 1.5
CL max - = -1.5
Root Chord: 1211.6 mm
Tip Chord: 456.8 mm
Wing span: 3009 mm
