you need to see a cross to slew it, that is acces by depressing the Radar fixtrigger to it's first detent (T1) the fix is done via second detent (TV). T0 is the postion of the triiger if it's not depressed, without a mod this can't be mapped on a two-stage-trigger like a Warthog stick has, so you have to assing T0 to a seperate button or use a mod (https://forums.eagle.ru/showthread.php?t=181720)
