Any thoughts on this one?
My Piet has an "A" engine, which sits on wooden rails. I havn't drilled the rails
for the engine bolts yet and I got to thinking. Why couldn't I put that off
until the plane was finished, then prop it up under the CG and move the engine
until it balanced perfectly, then drill.
Would it make a difference if I propped it up under the wing or set it on something
narrow and padded under a point on the fuselage which corresponded to the
CG??

Chuck,
Thanks for the comments. I got 5052 TE's from Wicks rather than the
3003 from AS&S, and they don't seem all that weak, in fact I'm concerned
about keeping the front end compressed enough between the ribs so as not
to screw up the contour (epoxy and clamps should do that?). ANYWAY, I'm
building the ribs in a way that I can change my mind if I have to;
bottom capstrip with a vertical end, top capstrip cut horizontally from
the end of the bottom capstrip out to a point which extends almost
exactly as far as the TE is supposed to (then I'll glue the TE up under
the top capstrip). I met Tom Fahy at a fly-in and he said that he went
with wood TE's for the same reason you did, so I could still lean in
that direction, cut off those top capstrip ends, and use the alternate
TE suggested on the plans.
The side gunner will prevent bird strikes.

--> Pietenpol-List message posted by: Michael D Cuy <Michael.D.Cuy@grc.nasa.gov>
Group-- with my cruise speed at about 72 mph and a headwind of about 30 mph
my ground speed
was down to around 42 mph going north into Wisconsin a few years ago. Nice
day, but Canadian winds were
slowing me down a bit.
I glanced down to my left and saw a school bus on a road that was off to my
left and parallel to my flight path.
After about two or three minutes I watched the bus slowly pull ahead of me
and then after about 5 minutes it
was a good mile ahead of me. It was a humbling experience.

I've been happy with my Tennesee Prop. www.tn-prop.com One of the few wood prop makers that use 1/16" laminations. Makes for a very strong and stiff prop. Good price too... about $550 They will make any diameter or pitch combo you want.

Douwe,
You could just set it up on the scales and move the engine till the calculations
came out right. Just have to figure in the missing cowl weight. There have
been a few programs around to plug the Piet numbers into, if you need one, I'll
send it to you. Just change the weights and the final numbers change before
your eyes.

Wow, now I won't be able to just hop over and take a look when I've got a question
about something.

Well, I guess I'm just in the mood to type tonight !!
I'm moving my plane from Benton to Cook Airfield. The first thing the new
owners of the airport want to do, is tear down the old row of hangers that I
am
in, to make way for new 'Nested Tee' hangers. <snip>

Yes, that does make a difference on the distance of the roll out. Gonna have

Douwe,
I've thought about that, too. Yes, either way would work. That's the way we
did it with R. C. Model airplanes. Problem is that there is no place on the
bottom of the wing, at the C. of G. that would support 650 lbs, or so. On the
bottom of the fuselage you might be able to balance it on a piece of round
tubing, or dowl pin, but it would surely be very top heavy, and adjustments of
1/16" to 1/8 would probably make a big difference. With all that weight on a
very narrow point, I'm sure it would leave a permanant impression on the bottom
of the fuselage. That would give the C. G., but unless you had scales under
there, you wouldn't get the empty weight. Best to just stick to the
conventional way of weighing the mains & tail, and doing the calculations.
