Take-Off:

Trim full down, VTOL/Flaps 3/4 down, then throttle to 100, the plane will smoothly pitch itself up at 100-110 km/h, though you can pitch up from 90 km/h. Don't forget to retract the gear.

Landing:

When lined up with the runway, Keep the thrust at 25-40% depending on fuel level and remaining payload, and carefully slow yourself down by playing with AG1(if you feel so). With your landing gear extended, at 100 km/h you better have VTOL full down, also don't forget to play with Trim and rudder.

Cruise/Patrolling:

Tail camera view:

Your maximum speed exceeds 400 km/h at low altitude, and increases slightly until 6000m. Presence of clickable buttons in a turret camera allows you to do some stuff in the autopilot mode, including weapon usage. Preferable autopilot speed is 350+ KM/h.

Your HUD is just there so you could watch out for the flight properties of your plane while tracking a target.

Combat:

Your missiles are the ten of S-5Kor laser-guided rockets and 4 fire-and-forget, no-lock-required Fingerpunch ATGMs. The preferred max range for ATGM is 10 km plus your altitude over target. For S-5Kor it's 8 km.
ATGMs are more agile and fire-and-forget, don't give a warning to your targets until impact, but they can't hit aerial targets.
S-5Kor needs you to keep your target in the cone or camera, but is noticeably faster and pretty resistant to counter meaures, also they can hit air and ground targets alike, though their warhead size is barely enough to wreck an AA tank.
OSV-10.75 is an experimental lightweight automatic weapon derived from OSV-96 anti-material sniper rifle. Its 10.75mm ammo was developed with a goal of creating an ammunition that surpasses the classic 12.7mm ammunition in its ballistics while having less weight and recoil. These two guns fire HEIAP ammo. You need to precisely point your plane at a target to hit it. Dont forget to turn off AG3 when going for your guns.
Here it flies with emptied launchers.
