It is smaller and lighter-looking than an Apache: 14.1 m fuselage, 13 m rotor. Keep the contract of the previous version (node names, pivots, Paint material factor, paints in nodes.json, game weight). Start from the previous build script and change what the critique names; deliver the same files.",
