In less than 100 years we went from the first plane the Wrights built to 
  the Space Shuttle, the F22 and more im****tantly for this conversation 
the Cirrus SR-22. For over half of that century we've told out kids 
through magazines like "Popular Science" that flying cars are about 10 
years away. I personally think you have bought into the "Popular 
Science" mindset and if you aren't a 15 year old kid (which I'm not 
really sure that you aren't) you will probably grow out of it.

Will there be electro-mechanical controls in future GA aircraft? Of 
course there will be. The 601XL I'm building has electro-mechanical in 
it running the elevator and aileron trim. Will the entire wire or 
push-rod system be replaced? If the parts get to the point where they 
are of equal or less weight AND the system is as reliable AND cost is 
equal or less than what is used now the answer is yes.

If the Wright brothers were to come back to life today they could look 
at the SR-22 or the other aircraft I mentioned and understand why they 
fly how they do. They could probably fly the Cirrus with no more check 
out than is required of the average guy who is transitioning from a 172.

There is a reason for this. Airplanes work the way they do because they 
are flying in the same environment they were in 1903. They have to 
overcome the same gravity and they need to be as light as possible for a 
given job.

You have all these grand ideas that replacing everything with 
electronics will make aircraft easier to fly and cheaper. Yet you have 
never really told us your idea. You just keep saying things like, "Well, 
my design will get around that problem."

I know you think that there is all this open source software and 
electronic hardware that is available and cheap. And you have been 
raised to think that there is not problem that a few silicon chips can't 
fix.  BUT I can pretty much assure you that there are a lot of people a 
lot smarter than you in the world and some of them work for companies 
called Lockheed and Boeing and even Cessna and Cirrus.

Tell me this. If it could be done cheaper why aren't any of these 
companies doing it? It isn't like they are making all the money they 
want and I'm sure any of them would be more than happy to increase the 
size of the market for aircraft by 1000 fold.

I want the flying car I've been promised by "Popular Science" and so do 
a lot of other people and Boeing and Cessna and Cirrus and the other 
know it. They just don't know how to make it because with technology 
available today it can't be made.
