Question about free GEFS flight simulator Helicopter flight dynamics and turn handling when compaired to a real helicopter

Recommended Posts



In the free to use web based flight simulator 


( needs free google earth installed and runs fine from opra or firefox when brousers  if you wanna give it a try ? )


there is a model of a huges 300 helicopter


that really hard to fly !!




I have a question about what happens when you want to turn the helicopter really fast from 40kts forward flight and get it flying in the oposite direction 

using a 180 degree pirouette turn manouver


(sort of manourer you might see done by a helicopter display team)



This is what happen in the sim



From straight and level forward flight at 40kts  say 100 ft agl



kick in some right rudder 


helicopter starts to yaw to the right  but then the nose starts to pitch up automatically requiring pushing cyclic forward and right abit


awell as the collective needs to be reduced abit ?? during this turn manouver  


so as to keep the nose aimed at the ground  thought out the turn at an angle of 45 degrees approximatly



then as soon as you reached 180 degrees turned


cyclic back to pull nose up and increase collective to go back into into forward flight again ( only this time in the oppsite direction )



what do you need to do in a real helicopter to achieve the same 180 pirouette degree manouver from 40kts forward flight??



if any one  could decribe what needs to be done with the controls to achie the same manouver i would be greaftul as then i could compare to the sim



if the sims wrong i will not fly it any more as this could cause bad practice




really looking forward to a reply

Important update about helicopter flight model
I found out what was causing the heli nose to pitch up strangly in the sim when kicking in full right or left rudder from forward flight
in the joystick options I had roll mix set to 2.0  ( this must have been causing the nose to pitch up )
joystick options
reduced roll mix to 0.0
set sensitiy to 2.0
set expo 0.0
and now the helicopter flys perfectly !!
please forget my first post about this as it was incorrect  and the flight model for the helicopter is perfectly good afterall !!!
