You have to mouse over the rpm handle and using the mouse slightly raise it and then pull it down hard. It will then up your rpm to 3,000 + . Doing this I have gotten it to go about 3,600 rpm. Once you have done this you can use the throttle to modulate your rpm. It is weird and unwieldy but it works. I am not sure if this is a bug or what - but it needs fixed ASAP. I also cannot get the aiming light switch and rehostat to bind to my hotas and there is no option for charging the guns.
