  "notes": "front (throwing direction) faces -Y; shown cocked with a round stone in the spoon. catapult_arm has its origin on the torsion axis (local X): rotate it about X, positive angles swing it up and forward, about +115 degrees brings it against the padded stop bar. catapult_pull_rope is the winch rope hooked into the arm - hide it when the arm is released. The four wheels (catapult_wheel_*) rotate about X around their hub. Friendly toy-like look, no text, no emblems",
