I'm 99.9% sure this is not a problem with the game and is in fact something I'm just doing wrong, but I can't seem to keep the Hueys in the air on the military missions!
I take off and fly towards the objective as normal, flying straight and level I ensure that I am not exceeding the speed limit of the engine etc. Then before long the airframe begins to shake rapidly. This develops into violent shaking which eventually turns into the rotor blades slowing down to a stop (presumably as the engine has died) and I fall to the earth like a screaming khaki painted rock.
In conclusion I ask, what am I doing wrong!? I must be forgetting something stupid, but as a n00bie I just don't know! I've ensured that the blade lock is OFF... I just don't know what it is lol.
Thanks for your help.
