Looks good. My only question is why use a parachute? The whole point of the design is that it inherently helicopters, so doesn't need a separate recovery system.
As for monocopters, I have had some very mixed results. My first one, copied straight out of the NAR handbook a few years back, absolutely sucked. It went up 10', and over 20', nearly hitting the people loading their rockets on the next set of pads. I then took that design and totally rebuilt it, building up an aerofoil around some central struts, streamlining the nosecone, cutting down the weight by 30%, and generally making the whole thing much more aerodynamic. The result was spectacular, flying up at least 100'. However, when I went back to launch it again this past month, after 5-7 years of sitting in my closet, it did not fare so well. it took off at a pretty serious angle, flying right over the crowd, and falling to the ground with several seconds still on the ejection charge. It landed pointing the engine straight at a small child :y: luckily when it spit the engine it missed...
