Heli controls bugged?

I dont know if this is just my issue or a "feature".

But since some point during first wave of open beta (I say "some point" because i remember that previously it behaved as expected ... until it didnt ... without me changing anything in the control settings) when I enter helicopter i cant take off without using assisted ascend key. My right mouse button instead of changin pitch and yaw does only free look (even after reseting controls to default), which makes it virtually impossible to fly.
