Having just watched the Roton rollout (www.rollout.org), I must say that this prototype, at least, doesn't look exactly like the "artist's impressions" on the Rotary Rocket site. The top of the rocket, where the rotors are attached, did not look as if it would support the idea of launching with the rotors folded down. I wonder if they ditched that idea, and plan to launch with rotors out? Wouldn't that put a lot of stress on the hub?
