While AT missiles in both Blackfoot and Kajman have great manoeuvrability, these anti tank missiles won't lock at the target if your cockpit sight isn't aligning your desirable target, moving your head freely and looking at the target under you will not enable you to lock the missile. This is just so wrong...
Watch the video, which explains everything ---> https://www.youtube.com/watch?v=IoM_t_JQgyY
While flying at altitude of 400 meters and trying to lock the target 1 km away, it's fine, but once you go higher than 400 meters, you loose the locking ability, this basically means the aiming angle of missiles while aiming down only lies around 36 degrees...
Also, HMD feature could be much appreciated, only it has to show the view of the actual helicopter optical device, while clicking right mouse would enter full screen mode (Just like rifles with any optical sight)
