The Heliborne radars have been poor for some time, rarely ever do you get 3rd person locks and the MTI scan I’ve always found useless. I just switch it to A2A (and reduce the scan to 180 degrees or less on Apache/Z-19) for air self defense.
Interesting, I’ve always used MTI on the Mi-28NM for the past few years and it’s always been reliable to the point that I’ve co-bound my mouse wheel roll up key to switch radar lock and lock radar target as a ghetto TWS and mouse wheel down and free spin the mouse wheel to spam radar lock in third person
Now when you do that, it rarely updates - even worse than it was before.
