I think you slightly underestimate the power in the main rotor:

Notice how the rotation does not stop even when impacting the ground. I only fly RC helos, albeit with totally different weight ratios but I do have respect for flying blenders of every size above ~60 cm. Also, does it really take that much energy to cut through a light-weight aircraft structure? Its not exactly steel/concrete.
