You have proven none of your points below.

So...having an aircraft that is

0. smaller
What?  Pilots want bigger.  Biggest they can afford.

So basically, if a pilot has a choice between a C172 that is size of
a C172, and a C172 that is size of B-52, you're saying he'd want the
latter? [Assuming he could afford hangar fees.]

1. quieter
You have not shown that you can get quieter; first it has to fly with
good

performance, and what you propose can not with the proposed power
plant an
d
added weight and complexity.

What I have in mind is lighter than 60HP ICE.

2. lighter
Haven't you been listening?  Everything you propose adds weight.

But is lighter than that which it replaces.

3. more fuel-efficient
First it has to fly well.  Your fuel cell will not.

I never said anything about fuel cells [yet].

4. more comfortable
Not going to happen, unless you exceed your weight budget.

Computer-controlled auto-stabilization would probably do a bettter job
of maintaining comfort than pilot himself.

5. easier to control
Perhaps, until your fly by wire, unreliable system craps out.  What
will
it be
running, microsoft?  Gads!  How many backups will it have?  At least
two, right?
That would be the minnimum number of acceptable backups.

Probably. If cost is cheap enough, 3, 4..whatever is necessary.

6. more stable in adverse conditions
Only you say so.  You want to make it shorter, and that will not be
more
stable.

Not an inherently true statement.

Try ballancing a bowling ball on your finger, then a 16 foot 2 x 4.
 Whi
ch is
easier, or put differently, more stable.?  Hint-not the bowling ball.
 Your fly
by wire has to be reliable, and that it will not be, and it has to
have so
ftware
developed, and that will be too expensive to be done, and if you had
the m
oney
to do it, someone would probably die while developing it.

I don't see "too expensive" for software to be done, but as far as
dying, it is very likely that there will be serious injuries, but from
what I have seen, that is typical of this industry for new designs.


Oh you so droll
