I've started building wing ribs and got 5052 aluminum TE's from Wicks
early, so I could cut a cross-section and figure out exact measurements
for attaching to the capstrips. I plan to use the "Fig. 3" version that
Ord-Humes describes in the EAA Wood techniques book, TE glued under top
capstrip with gusset beneath. Curious if anyone using aluminum TE's has
a photo of how they did it because I've scoured the archives for a
picture reference without luck, even though there are lots of pro's and
con's discussed re: aluminum TE's.
Thanks,
Mark Hodgson

Hi again Pietnics!
What might be an expected, static RPM range for a zero-timed, healthy, stock
Ford engine/Zenith Carb with a Hegy 76x42 scimitar prop? Educated guesses
or empirical knowledge anyone?
Thanks,
Larry Prange

Larry, After much effort to get my 'A' adjusted, it now runs quite well. I
have nothing against which to compare it but I recently ran it for a full five
minutes at full throttle (static), then closed the throttle quickly, followed
by a quick move back to full throttle. It had started on the first pull and ran
smoothly in all modes and did not hesitate at all through the throttle
changes. It registered just a bit over 1650 RPM at full throttle and idled at about
500 RPM.
It is stock throughout. Original head and manifold, Zenith model B carb and
babbit bearings. Timing set at 27 degrees BTC Total time to date 22 hours
(mostly fighting the original carburetor and timing problems). I won't be running
it again until I start taxi tests ( hopefully in the next couple of weeks) I'm
comfortable with flying it as it now sits. Hope this helps. Don Hicks

Larry,
Forgot to mention in my last post, one rather important item. My prop is
also a 76x42 ( made by Chad Willie and is top quality work) Don

Ok guys, all this talk about big guys and Piets
has me worried. I am 6'1", and weigh 300 lbs (I
am built like a linebacker). I am considering a
Piet with a Corvair motor. Would this be an
impossible CG problem for an Air Camper build?
Would there be any way to carry a normal weight
passenger? Or should I just start looking at
other aircraft plans?
Thanks,
Ron Hargrove

Thanks to Chuck and others for the comments. I have one other question then.
Is it better from a flight characteristic point of view to move the wing
back or extend the engine forward/
It seems that moving the wing back is going to make getting in and out all
the more difficult.
But I want to give it the best flying characteristics too. Comments please.
Thx
Les

I'm 6'4" and 195lb. I had to lengthen the rear pit about 2" and made it 2"
wider. My firewall is about 1.5" wider. Very comfortable fit. You might
consider widening 2.5" or maybe even 3" at the rear seat and maybe 1" wider
at firewall. As for the CG issue..... not really a problem if you go
Corvair with electric. A Corvair with starter, alternator, intake tubes and
carb will be about 255lb or so (give or take 10lb) You may need to make the
engine mount a couple inches longer but I see no significant problems in
doing that.
As for ability to carry a passenger... well... depends on how light you
build. You may be able to carry a 150lb pass. assuming you keep the empty
weight at 650lb, carry 96lb of fuel or less and gross the aircraft at
1200lb. 1200lb gross is on the higher end of the spectrum but I suspect it
would be fine.... well... let me say with a GN-1 it would be fine. I have
never seen a Piet structure up close..... may not be quite as stout as a
GN-1.
I plan on grossing my GN-1 airframe at 1200. I'm using a Corvair that
should put out about 95-100 hp propped with a large diameter low pitch 66x29
wood prop. I want to use my power for climb (cause an Aircamper ain't
supposed to be a rocket anyway)
