    --> Pietenpol-List message posted by: rhartwig11@juno.com Keri-Ann, This is a discussion list, not free advertising for a business. A sure way to turn off Pietenpol builders is to take unfair advantage of a free service that is provided to promote aircraft building. Matt Dralle would probably appreciate it if you would send him a few hundred bucks for the advertising you have already done. Dick Hartwig rhartwig11@juno.com

    Subject: Pietenpol on film
    --> Pietenpol-List message posted by: Bill Church <eng@canadianrogers.com> Mike, As I remember it, that's just in the trailer (editing). But if you watch the trailer, when they show the aileron moving before takeoff, the aileron has quite a warp in it, and then when the plane is rolling down the runway for takeoff, both ailerons are hanging down, like flaps. I don't think the Piet in the film was actually airworthy. The few flying scenes show the "Pietenpol" climbing like a fighter jet - even with that added drag of the big copper fuel tank on the wing :) One scene that was funny in the film was showing a young boy working on "rebuilding" the Stampe into a Pietenpol. They showed him "working" on the ribs (which were plywood) with a hammer! I bet the producers of this film never expected anyone to pay attention to this stuff.

    Oscar, See page 8 of the attached document. I believe it has what you are looking for. It is a recent document from Continental, and has all tourqe specs for a LOT of Continental engines. I can't remember where I found this now. If I'm reading this right, exhuast manifold nut torque should be: 200-210 in/lbs for a .31-24 fastener, or 100-110 in/lbs for a .25-28 fasterner I'm guessing a .25-28 is 1/4", 28 threads per inch, and .31-24 must be 5/16", 24 threads per inch?

    --> Pietenpol-List message posted by: Steve Ruse <steve@wotelectronics.com> I use 1,700 RPM, and probably lose 75 RPM on a single mag, and more near 100 with carb heat on my A-75. What static RPM do you guys usually see, and with what prop? I get about 2,400rpm static, and only 2,450-2,500 flat out (full throttle level flight).

On the sides , the plans show some little pieces of 1/4 x 1/8 for this, just one comment here.. did you install first all the metalic stuff , or did you cover first and install after...

I use 1500 RPM indicated for the mag drop test. Any more than that, and I have to apply considerably more pressure on the brake pedals. I checked my mechanical tach in the panel, to an electronic tach, and it reads 100 RPM too low at 2000 RPM. I get about 50 RPM drop for each mag, and about 50 for the carb heat, too. I have new Slick Mags...well they were new when I assembled the engine, about 200 hours ago. No problems with the Slicks, so they were worth the $1000 investment. Chuck G.

Anybody know what the recommended torque is for the nuts holding the exhaust stacks to the studs on the Cont. A-65? I just removed my exhaust pipes for sandblast & paint. The Continental Overhaul Manual calls out Torque Limits on 5/16 - 24 nuts & screws to be 180 - 220 in. lbs., which works out to 15 to 18.3 ft. lbs. I've never found anything=20to last on exhaust pipes. This time I'm using VHT Flame Proof Coating (SP-101) Flat White, and supposed to be good to 1500=BA for painting exhaust pipes & headers. I bought it at the local Hot Rod Shop. It specs sand blasting, and baking in the oven at 600=BA to 650=BA. I suggest the use of the tall brass exhaust nuts for this install. It was no problem to break them loose with 1/4" drive tools, and came off with my finger. I used the thin metal gaskets, with the bead around the big hole. A couple of small areas I noted black carbon traces, like they were leaking, but saw no evidence of leaks up against the head. There wouldn't be enough back pressure, with the short 2 into 1 pipes, for it to leak very much. Another thing I always do, when dealing with exhaust, is to plane the top of the flanges (gasket surfaces), with a long fine bastard file. You need a long enough file to reach both flanges at the same time. It shows the high and low spots where I dress independently, then finish again with strokes across both flanges, to be sure they are on the same plane, and no stresses are induced when the nuts are torqued. When I assembled them 2 years ago, I coated both sides of the exhaust gaskets with 'Copper Coat', but when I took it apart yesterday, I found no evidence of the copper coat. Chuck G.

I get about 2,400rpm static, and only 2,450-2,500 flat out (full throttle level flight). I have a Cont A 65, with my home built 72 X 42 prop, and I get about 1900 RPM, full power static run up (in the chalks), or on take off roll. At full power level flight, when the prop unloads, I see 2150 RPM indicated. Like I said on a previous post, my tach reads 100 RPM too low, so those numbers are actually 2000 and 2250 respectively. The ASI indicates about 72 to 75 MPH, but it also reads about 10 MPH too low, so I'm doing somewhere close to 85 MPH, on a full power level flight run. I pull power for cruise flight between 1800 and 1900 RPM, and indicate about 65 MPH. I think fairing the gear legs helped a little. The A65's rated power is 2300 RPM, so I consider mine to be a cruise prop. I think I'm well with acceptable range. Chuck G. NX770CG

Javier, I didn't cover the plywood bottom of my plane. Just overlapped the corners and the aft edge, about 2". My hardware is exposed on the bottom for maintenance. I installed the hardware, like the lift strut / landing gear fittings and the fittings on the empenage, then covered them with the fabric. I used 2.7 oz fabric on the fuselage and wing, and used 1.8 oz fabric for the ailerons and empenage. Chuck G.
