For landing i use full flaps and sometimes turn off the engine on final approach if needed, most frequent mistake is landing at too high speed (it is a light craft with low wing loading so glides a lot). Second most frequent mistake is approach at a too steep angle, unless you have to (AA battery , enemy CAS etc) give yourself min half a click for your final lined-up with the runway. The greyhawk is extremely maneuverable so it can pull some great stunts even on landings but it is more risky ...
As far as lasing moving targets , with enough patience (if given time and not engaged by AA) you can even ctrl-T lock on an individual infantry element and it will track. Beware though if that lased inf dies before you launch sometimes i have seen the laser "relocate" somewhere to a far horizon ....
On a defensive note , you can avoid AA fire by maneuvering so it may be worth the effort to try and save your UAV given the respawn time
Final note: you can have more than 1 Darter in the air at a given time, even with their lasers locked on different targets which can help when first striking an area full of hyper-active, on the move AAs ...
Have fun and keep it smart ...
