The kids' helicopter blades are bendable, but the heaviest one only weighs 135gm (and has a camera). You can stick your fingers in the blades when they're running and they simply stop. Boys just have to do that. I wouldn't do that with stevey's carrot chopper!
At 700gm the ROAM-e will need just over five times the force of the heavy chopper's blades (which are contra-rotators, like the ROAM-e).
Coming soon to a store near you, page-62
