  "real_size": "wheeled counterweight trebuchet, approx. 3.3 x 6.8 m, 7.5 m tall when cocked, throwing arm 6.8 m",
  "notes": "front (throwing direction) faces -Y; shown cocked: long arm down at the back, sling with a round stone lying in the wooden trough, counterweight box raised at the front. trebuchet_arm: origin on the main axle, rotate about local X (positive = throw, about +150 degrees at release). trebuchet_counterweight: origin on its hinge pin at the short end of the arm - parent it to the arm and counter-rotate so it keeps hanging. trebuchet_sling: origin at the hook on the arm tip - parent it to the arm. trebuchet_pull_rope holds the arm down to the winch - hide it on release. The four wheels rotate about X. Friendly toy-like look, pennant without emblem, no text",
