Key Features

  • Attachable Slingload Cargo: Vehicles (light cars), supply crates (including Arsenal boxes), and more.

  • Manual Attachment/Detachment: Use your controls to pick up and release loads dynamically in flight.

  • UI: Hud indicators easing operations from first person.

  • (Quasi) Realistic Physics: Smooth cargo movement, ground interaction, collision detection, and crash handling.

  • Visual Rope: A simple rope with attachment points.

  • Arsenal Crate Integration: Automatically swaps visuals for transport-safe mode and resets when grounded.

  • Ground-Snapping Logic: Automatically levels and aligns crates/objects with terrain upon release.

  • Collision Safety: Cargo can be damaged or destroyed on hard impacts. Detaches when hitting objects in flight.

  • Engine & Altitude Safety: Slingload is only available with engines running and safe lift height.

  • Sort-of Works in Multiplayer: most things work, but can be janky and unpredictable sometimes.

Liftable Objects

  • Light cars (UAZs, Jeeps, Civilian cars etc.). Objects moving faster than 0.5 m/s are ignored.

  • Arsenal boxes

  • Mi-8 can lift heavier HMMWV cars, while UH-1H is limited to up to 1500 kg

Usage

  • Get into the pilot seat of a MI-8 or UH-1H and start flying.

  • Use the autohover feature to steady over the liftable object. Chopper must be over 3 meters off the ground and within 10m radius of the object. If you are too low, the indicator will glow red. If there are no objects in vicinity it will be grey.

  • Watch the UI indicator turn blue to indicate that a liftable object is within range.

  • Press HOME or DPad Left to attach the rope. The UI indicator should turn green if successful.

  • Transport the object to new location. Bumping the cargo into object will make it eject. Dropping from too high will damage it.

  • Lower the object to the ground and release with HOME or DPad Left.

  • Fly away.

  • Change the bindings for both keyboard and controller at the bottom of the Helicopter menu (Slingload toggle).

Known Issues

  • Can be choppy in MP, not super optimized but the basics should work. Test in basig GM to see best results.

  • Arsenal boxes can behave a bit erratically, sometimes dropping though the ground, so set them down gently. Also the replacement box that appers in flight can sometimes appear in wrong location.

  • Shooting at cargo might not always register, so shoot at the chopper better.
