This is an intermediate, but logically complete build where the full ground behavior of the aircraft has been implemented. This was necessary in order to smoothly approach loading areas and prepare for cargo operations.
At this stage, cargo loading into the Scarab and testing flight physics with a loaded aircraft are not yet implemented. However, you can now freely taxi and move around on the ground.
Ground Mode
A new Ground Mode has been added. The Scarab will automatically switch into this mode after 5 seconds, provided that:
- At least one landing gear strut is in contact with the ground
- Ground speed is zero
Engine power settings for this mode can be adjusted in:
\Plugins\FlightPhysics\Resources\engine\scarab_ground_basic.xmlControls
- Pitch – forward / backward movement
- Yaw – left / right steering
Braking
The landing gear can now apply braking:
- VTOL Mode and Ground Mode – all four landing gear units provide braking
- Plane Mode – only the rear wheels are used for braking (there are plans to also include front wheel braking at very low speeds)
Braking forces are passed directly into JSBSim and processed as part of the flight dynamics model, taking into account speed and center of mass.
Because of this, the Scarab may pitch forward during heavy braking – this is expected behavior and comes from the physics model itself.
