Subject: | Re: Stabilizer incidence |
You might try a couple Mylar strips (old cassette??? ;-) attached to the
wing T.E. to show how much of a "downwash" you're getting from the wing --
if they are just long enough to just miss the Stab. L.E. you'll have an idea
what angle of attack it's working at. Roll them up & tape them to the
center section till you get to the "Test Area".

OK, so now we have cameras. Next step is to tape bits of yarn all over the
tail, particularly the rudder, fin and fuselage to show the vertical flow.
Taping to the stab and elevator for horizontal flow and possibly any
stagnant
areas on the bottom.
Don't forget to have a few guys standing around in white lab coats with
clip
boards, horn rim glasses and those plastic pen thingies in their pockets.

Maybe some video of your tail (your AIRPLANE'S tail, that is...) would
answer some questions...

Hey Jim, great idea !! I have video pointing aft, from both sides of
the cockpit, watching the smoke trail. Ya can't really see the position of
the flippers very well, because of the angle of the camera, but it does
appear to be slightly down, and I didn't note how much fuel was onboard when
I did those flights. I will do several more flights, paying particular
attention to the camera angle, and fuel onbd / C.G. location. One thing
I've learned from all these flights with the video camera mounted, is that
in normal bumps of turbulence, the camera exaggerates the movements. Quite
often, it looks like I'm bouncing all over the place...on second thought,
maybe I am, and I'm just used to it. It's very challenging to shoot good
video while flying the plane trying to keep the subject in the viewfinder.
I have to slip & skid circling a target, causing the ball to bounce back &
fourth (the one on the panel). I have some really great video of three hot
air balloons landing, and deflating. I circled them for about 15 minutes
during their operation, with the camera pointing out the left side. I still
have to do a flight with the camera pointing directly at the instrument
panel. I'm splicing and editing all this video, to give the impression of
many cameras mounted on the airframe. I'm really learning a lot, about what
it takes to get good in flight video. It's looking pretty good, but I've
been having problems with the video editing program (Pinnacle Studio 9).
I've been in contact with them, and I have to un-install, and re-install it.
That's a scary thought, because I don't want to loose any of the many hours
of video I have on the computer. I still haven't got any of the video's to
a finished point yet, but I do some stuff to them almost every day. They're
all looking pretty good, though...if I can just get this editing program to
do the stuff I tell it to do !!

Gotta smile at this. Long time ago as a student pilot planning a cross
country into a strange airfield, I figured I'd take a pair of binoculars and
scope out the field layout on the way in. Well, I found out that you (or at
least I), cannot fly a plane while looking through binoculars. I was good
practice for recovery from unusal attitudes. Maybe not that bad, but I
quickly abandoned that idea. Looking back, that was a pretty stupid idea
anyway cause inbound to an airfield is the LAST place you want to fly with
tunnel vision!

PS - I was 17 or 18 at the time and full of stupid ideas. Now my ideas are
still stupid, just more expensive.

Hey !!
You guys are coming up with some great ideas !! Cassette tapes...I still
have some old 8 track tapes !! I'll be back up in the Test Bed at the end of
the week, after this next front goes through. I don't have any lab coats, or
pocket protectors...I wear old tee shirts, and make notes on my hand...that way
my notes can't blow away !!

Divers always spit in their goggles and rub it around to prevent fogging.
However, I don't think they chew tobacco...

Subject: | Selling my ribs, and plans |
--> Pietenpol-List message posted by: Kent Hallsten <pietbuilder@yahoo.com>
Hi Everyone,
It has been quite a while since I have been on the
forum. I see all familiar names and am happy you guys
are going strong.
I am selling my ribs and rib jig on eBay. I see Mike
already posted the link. Thanks Mike.
Last January, 2004 my wife was diagnosed with Ovarian
Cancer and our family life took a tailspin. Eventually
she pulled through with a magnificent Doctor, great
attitude, and all of us pulling and praying for her.
We are fine now but during this past year and a half I
lost my desire to build, and found myself spending
more time messing around with my other passion,
motorcycles. It seemed more satisfying to work on a
bike than my plane, I can't figure that out but I'm
running with it. I'm selling the woodworking stuff and
also my Piet blueprints. I'll have the prints on eBay
later this week.
Good luck to you all, keep building, keep flying.
Kent Hallsten

The more reading I do, the more I see GN-1s and Pietenpols with claimed cruise
speeds of 70, 80, & 90+ MPH. My GN-1 with an A-75 cruises at about 65mph at
2,200 RPM. Going to 2,400 or so will net me maybe an additional 5mph. Nowhere
near the 80+ MPH I see some people claiming. Now I understand I'm in a
Pietenpol, and getting somewhere fast is not a concern, but I'm wondering if
other people's numbers are real, or if the prop (or some other factor) is
making my plane slow.
The prop on my plane is a fancy Prince "Q-tip" composite/wood prop, I don't know
the exact numbers, but I am trying to get them from Prince. The previous owner
told me this is a climb prop, and the plane came with an extra prop that he
said was more of a cruise prop, and would give maybe 70mph.
Is the prop I'm using possibly slowing me down? The plane is right at 600lbs,
I'm only ~170lbs, and the airfoil is the original Pietenpol airfoil. I see
some people claiming 80-85mph in GN-1s with A-65s. The higher cruise RPM of my
A-75 should give me an advantage over them. What am I missing? Should I
really expect to get 80+mph in cruise?
Thanks!

Stupidity is sometimes only in the mind of the beholder.
The Wrights were a couple of stupid bicycle diddlers that
didn't know you needed suspenders to hold everything up.
Then there was Edyson, Bell, Watt, etc. All stupid time
and money wasters.
