Magnet crane: - If we use the IntertiaTensor Unity thinks we should have, the crane is really wobbly with the arm extended straight up - If we use my custom IntertiaTensor (set to values that act like the arm doesn't exist), the crane behaves in unexpected ways with the arm extended far out front Compromise instead and go 50% of the way between them. 1. Set the inertia tensor to what Unity thinks it SHOULD be for the current arm position. 2. Set the inertia tensor to half way between the above and my custom one.
