Actually, according to the manual the normal Vr is 171KIAS, but you have to make sure that you rotate AFTER this point. Nice and easy rotation does it very well.
Pull up to about 5-7 degrees until you lift off then pull to 10 degrees, gear up and then climb at 12 degrees.
It helps to have a small 'spot plane' view in the left hand upper corner to see when you have lifted off. You can do this by pressing 'ctrl + Q'. However, do not take you eyes off the fligt panel as the aircraft is likely to point the nose downward if you ease off. Only use the spot plane view to check you have lifted off safely.
At about 1000 feet, turn on the AP
and engage the Vertical speed at about 2000-2400 feet per minute. Keep holding on the joystick until the AP
intercepts with your nose up altitude.
