How do you drop Hellfire Lima at 90º?

[Blaine Stars]

I saw a guy in a video releasing the hellfire Lima at 90º, so far nothing much in the video, I went to see it and it didn't work for me, do you have to do something different to release it? follow the video link.

Just out of curiosity I tried it several times but managed to hit my target only a couple of times. The Lima will fly and turn 90deg but has a slim chance of hitting the target though often near it. (2nd trigger detent to override yaw limit firing parameter.) Tried it with the K too but it just flies straight ahead.

Are you using the second trigger detent? Performance inhibits (in this case, yaw limit) will prevent firing with the first detent. Make sure you're also not too close as the missile needs more space to maneuver for such a shot.

The K won't do this at all, it only looks for laser energy along its flight path.

I've done a few this way from the front seat.  put george menu in "combat" mode, align him, then give him right or left flank command.  LMC+IAT and start an RF driveby.
