"Whats the primary functional difference between the A-Star and 204?"
You did have me stumped, because I think all helicopters are a very uncouth way to fly. To me the 204's a guzzling, overbearing Hummer, and the A-Star's OK like the Renault Laguna, but not my favorite car. Both have too many parts trying to whirl and vibrate themselves apart for my liking. I've enjoyed some minimal helicopter training, but they are specialized machines far beyond my budget.
RTT: The flying car, like the flying boat involves many compromises. Water and sky do have more in common than sky and street. With a seaplane you have an unwieldy boat and a less than ideal airplane- but it's a very fun combination. I love flying seaplanes, both for the feel of coming down from the air to touch the water, and also for the beautiful places to which a seaplane can gloriously transport you.
A roadable airplane involves many more compromises than a seaplane. I think
Molt Taylor came the closest, during the latter part of America's prolific mechanical creativity. Today, it's very hard for American mechanics and engineers to work so independently and creatively as in the 30s-50s, since liability and corporatism have driven independent craftsmen who build personal planes for a living into near extinction.
Roadable Aircraft are a wonderful dream, but still impractical not only technically but socially. The freedom to personally move about the sky is both resented and hoarded, depending on which side you are on. In the air, you can't read the "No Trespassing" signs of private individuals, and you can't see the artificial borders and restricted areas laid out by governments. Every time I fly, I must give careful consideration to not offending these parties who only grudgingly allow this gift of freedom that is aviation. I am in the business of facilitating the entry of everyday people into the fraternity of aviation, and I can clearly see that my side is losing in the present. I must struggle on anyway, because this boundless soaring freedom is never really bound by so much regulation, incomprehension, and sometimes resentment from the ground. Even when we're all gone, the fantastic experiences of flying can never be taken away.
From 2,000 feet, I look down a straight stretch of road. No traffic. No Utility poles, no houses nearby, completely suitable, and in certain circumstances, I often have landed on roads. There is no air regulation against doing this, so long as it does not endanger lives or property. However, there are often local ordinances against the activity, so caution is the rule. One of my favorite things to do in winter is land on and Adirondack lake, pull up at the edge of Main Street of any of several small towns, and stroll around, get some lunch, etc. One of my dreams is to
bring my planes home to sleep, with a hangar and runway incorporated with the house.
Considering the technical and social problems with roadable airplanes, I think that many of the pleasures of such a machine are actually already available in certain wonderful circumstances.
Cosmic: I'm ready to try that, it looks like a lot of fun, but at more than $10/minute, I'm sure I'll continue jump out of planes, for the full experience at the same or lower price. Obviously, it's a great way for skydivers to develop freeflying technique, or to offer those unwilling to jump from an airplane one aspect of the experience.
