BTR-98-1 "Gryfalcon"

Imagine an old BTR: battle-worn, reliable, yet constrained by terrain and speed. Now picture the BTR-98-1 Gryfalcon, a flying armored personnel carrier capable of soaring over rough, hostile landscapes like mountains and dense forests. Equipped with a 27mm machine gun and two powerful jet engines, the Gryfalcon can reach speeds of up to 800 km/h, making travel from point A to point B a matter of minutes, not hours.
The BTR-98 has a special ability to jettison its wings and engines, transforming into a ground-state BTR.

However, this is still a prototype. Takeoff remains challenging due to instability, and landing is even harder given the craft's geometry and wheel position.

// Controls //

AG1 - Wheels (controlled with throttle)
AG2 - Turret rotation (controlled with slider 1 for base rotation and slider 2 for gun rotation, F to shoot)

AG5 - Parachute (doesn't work yet, idk why)
AG6 - Engines
AG7 - Lights

AG9 - Jettison aviation parts, such as the wings and the engine

// Tips //

Install the "Imaginary Weapons" mod for the gun to work.
Take off speed is around 100 m/s, the max speed is 221 m/s.
While taking off try to fly in a straight line by using Q and E.
Try landing on flat surfaces.
Quick save before landing.
The engines have a reverse thrust using slider 3.
Jettison wings when the speed is below 60 m/s and a few meters above ground.
