For 1" routed spars:
Moment of Inertia = 7.50
Allowable bending stress = 5132 psi
Volume of wood in the spars = 1.28 ft/3
For 3/4" solid spars:
Moment of Inertia = 6.70
Allowable bending stress = 6200psi
Volume of wood in the spars = 1.46 ft/3
The allowable bending stress for the routed
spars is reduced because
a form factor has to applied (per ANC-18,
page 36, 1944 edition)
You'll have trouble breaking either spar
option.
It's early and the caffeine hasn't kicked in
yet so the professionals
on the list might want verify these numbers.

Here's the info on the suppliers for the stuff I used for the vacuum bagging presentation
at Brodhead:
http://www.acp-composites.com/acp-vbes.htm Aerospace Composite Products. This is where I bought my stuff, you'll recognize the parts.
http://www.cstsales.com/index.htm The Composites Store. Another good source.
Brodhead.....what a wonderful place.

Brodhead (C37) to Brodhead (C37) Out & Back 20 sm Attempt flight to
Oshkosh, but the headwinds won out !! I had almost full power in, with an
indicated speed of 73 mph, pointing the nose west, trying to track north, and a
ground
speed of 17 mph !!

On this leg, I didn't climb as high, but I still leaned it out, with a higher
power setting of 2100 rpm, which I believe is why the fuel burn was higher.

All told, I burned 65.7 gal of fuel (Av Gas & Mo Gas), logged 18 hrs flight
time, covered 1171 sm, which gave me an average fuel burn of 3.63 gal/hr, and
17.8 miles per gallon. I am suprised that my plane doesn't get very good miles
per gallon, but I triple checked the numbers, and that's a little better than
I got last year.
I'm working on a long post about the details of the trip.

The "3 Piece
Wing Supplement for AirCamper and Sky Scout"--drawn by Vi Kapler in 1975
and revised by Dick Gleason in 1982 is part of those plans. It shows
only 3/4 inch spars for the 3 piece wing.
------------------------
Oh, yeah. There is that! Duh, I feel a bit goofy. I was zeroing in on
the original plans and forgot about the 3 piece set showing 3/4 in both
the center section AND the main wing panels. Says right on the 3 piece
wing drawing: "Designed by BHP". Good enough for me.

Quiet reflection and grinding and welding in my case Dick, and thinking

What are you burning? I have been at about 4.1 gph. I checked the engine manual,
it should be more like 3.7 gph. I was getting ready to do some trouble shooting.
My flying has been at less than 2500' at 2100 rpm.

I have always found that flight planning at 4.0 was pretty much on the money.
I get 4.0 on the C-85 in the Cessna 140 when I lean at altitude.

Hello everyone,
I need help. I would like to start building a Piet but am having trouble
deciding on an engine (suprise). Model A has big time classic look appeal not
so much perf and forward vis (correct me if I'm wrong). Corvair has more power
better forward vis not so much classic appeal (solely my opinion). If anyone
has good numbers on both I would appreciate seeing them as far as weight cost
range speed etc. Does the Corvair version use the extended fuse? Do you still
run an alternator with the Corvair. Money is definitely an issue but would like
a good running toy with max classic appeal. I'm not trying to stir up a debate
just looking for info so you can e-mail me direct to keep from plugging up the
list if you'd like. Thanks.
Bill
