Actually, that is the proper way of setting up the aircraft. Just
about every pusher configuration aircraft is stability relaxed empty.
As soon as pilot is on board the cg moves forward and the aircraft has
a positive stability margin sufficient for safe flight (well most of
the time - LOL).


Correct.

I misread the ad - I thought it said 2" in front of the wing - not wing
_CENTER_ - my mistake.

I'm pretty sure that text was not in the original item description. I
think it was added during the Dec-02-08 10:53:13 PST revision.

It was pretty obvious that thing would never fly. If someone paid money for
plans or sketches of that, and it was built close to specifications, it
would be an understatement to say that they had been taken, big time.

Way over built; wood too large, way too much of it. Hardware quality stuff
everywhere, it would appear. An engine that size is intended to fly
something in the 254 pound (old ultralight rules) class, not a 500 plus
pound monster with "questionable" aerodynamics. g

I don't know how much that engine is worth, but perhaps the value of the
engine, and the heat all that wood would supply in a fireplace or wood stove
may make it an acceptable deal! g

Considering the price of engines these days, I emailed for details out of
curiosity. He says it's a 25 hp Mercury, and assumes it 440cc from searching
the internet. ?????????????

He did volunteer in his first sentence that the prop was not airworthy.

A clean wing, like the Mitchell, will fly very well on 25 hp. But there are
probably lighter 25 hp, two-strokes around.

You mean not much lift for drag -right?

Dear MC,

I wasn't referring specifically to this aircraft (too little data)
but to faceted wing surfaces in general.

From what I CAN see ( at least on the lower wing ), the characteristic
transition surface(s) needed to make the faceted portion work, appears
to be missing.

Dear Scott,

I'm willing to be surprised :-)
A closer inspection may reveal a wealth of instruments and components
-- in addition to the engine -- that may be worth salvaging.
