This may sound sacrilegious, but how about using standard-issue industrial equipment paint for the engine? Rust-O-Leum and others offer such paint and I believe Ford blue is used quite often on tractors.

Clay; my apologies if it came off sounding like I was referring to the questioner in any sort of disparaging way. I was in fact referring to the Pietenpol family, who hold such a rich treasure but are troubled about sharing it with Canadians due to the current trade tensions. I myself would be happy ...

When Corky built my Piet, he mounted the gascolator at the bottom of the firewall, which makes sense from the standpoint of making the Curtis valve easy to get to for checking for water in the fuel. However, he actually mounted it with part of the bowl sticking down into the slipstream below the ...

The bottom of the pilot's seat on NX41CC is removable and I made use of that quite a few times in the years that I had the plane.

Before flying my Piet I had Cub and Super Cub time, Citabrias, and other planes with heel brakes and I had no trouble flying with them. My Piet had the Rewey toe brakes and I really liked those too. I never felt "over braked" even though my plane had Cleveland brakes and masters off a much larger ...

It's difficult to say exactly where heel brakes should go in relation to the rudder bar, but there are plenty of Piets out there with heel brakes. Mine had toe brakes so I can't help with anything concrete, but to get a general idea, look at the attached photo of the cockpit of NX41CC and note where ...

Some time ago I did a graphical/geometric study on the maximum elevator deflection angles up and down and found the deflections to be about equal. In theory, the elevators can deflect upwards 52 degrees from the horizontal and downward 60 degrees from the horizontal, but that's only theoretical. My ...

There is so much early aviation history in France. Henri Mignet flew the test flights of his Pou du Ciel (Flying Flea) near Soissons, which is way up by Amiens.

Got it. And if it's any consolation, pretty much anything in or on the passenger's seat is directly on the CG, so it won't affect the balance if you add weight there. In my W&B spreadsheet, I ran what-ifs to test the forward and aft CG limits. With the lightest possible pilot solo in the pilot's ...

Interesting detail: the tapered wedges that slope the front seat bottom just a tad. Improves the pax comfort over a flat seat bottom. Was it originally that way, or is that improvement yours?

N41CC, weighed with 3 qts of oil, prop, and its Cont A75 engine, no electrics and no starter, was 636 lbs. This is very close to what Mike Cuy's Piet weighs as well. They can be built light.

Douglas fir has been used in quite a few Piets, NX41CC included. Weighs just a tad more than spruce, is just a tad stronger than spruce in some respects, doesn't work quite as nicely as spruce sometimes, but is FAR easier to find and at less cost.

Are you building a new plane, or looking to replace some existing struts? If new, you might consider the extruded aluminum streamline struts that used to be from Carlson, now available from Wicks Aircraft Supply.

The same happened to NX41CC. I repaired the seat front twice during the time that I owned the plane, and the last time I did that I also added some supplementary framing similar to what you've done to provide more glued surface area to transfer the load from the plywood to the framing. I should also ...

There will be at least two factors to take into account: (1) how high can you comfortably step, and (2) will you be shifting the wing aft on the cabanes. If you shift the wing, you'll probably have to incorporate a flop panel into the trailing edge of your wing so you can get into the cockpit, or ...

It looks like an Air Camper rudder bar

-Oscar Z.

taildrags

Are you thinking of mechanical brakes, or hydraulic? Both have been done. Although I no longer own it, my Air Camper had a rudder bar and toe-operated hydraulic brakes. The brake masters were from a Cessna 172 and the wheels/ brakes were Clevelands from a Bonanza. Tires were 6.00x6 Aero Trainers ...

I have not heard of any, Tim. There is a likelihood that the reason for that is that far fewer examples of Sky Scouts have been built and flown than there have been Air Campers, and also that many (most-?) Sky Scout builders have implemented some of the tweaks that Air Camper builders and pilots ...

Tim, it sounds like you have studied the plans and other examples of the airplanes enough to get an excellent handle on what goes into building them. You are way ahead of the game!

Since the Scout is a single-place, there are some things about the Air Camper than won't play into your build. Most of the rest of it should be much the same, although the classic setup for the main landing gear on a Scout is different from what it is on the Air Camper, in that the Scout has the ...

Welcome, Tim. It will be interesting to hear & see what you intend to implement in your build of a Scout. Well, as long as it doesn't involve beta thrust or Cat IIIc instrument approach capability

Richard; you became a celebrity the day you acquired three four kilo papa and began your Pietenpol journey. But hey, there's nothing wrong with a little bit of publicity.

I am certainly not in it for the money. I'm in it for Pietenpol builders! However, I must say that people who supply the hinges in finished form do a beautiful job with the hinges that they sell. I also offer the oval Air Camper data plates that Brian Amato used to offer in aluminum (and may still ...

taildrags

It depends on what you're looking for. One source out there can provide you with complete, finished, nicely executed pairs of hinges and for a Piet, you'll need 9 pairs (3 pairs on each elevator and 3 pairs on the rudder). If you're willing to work with as-cast blanks and perform the hand operations ...

I think it's quite common in open-cockpit airplanes to just read static pressure at the back of the instrument rather than running a tube from an actual static port on the exterior skin, but I'll let others chime in.

Richard; the area that I had some problems with over the years that I flew N41CC was the front seat's front face vertical support plywood. On more than one occasion it got kicked by the pilot hard enough to break the plywood free (not by me though). I finally ended up tearing out the entire assembly ...

Wish I could remember the young fellow's name, but in any case you can go to the search box in the upper RH corner of this forum page and enter 'ferrule' or 'tail brace wire' or some such thing and you should be able to find a useful link or two.

There are some websites and videos that provide exactly that: step-by-step methodology for making those beautiful wrapped and folded wire ferrules and ends. There was a young builder in this group who is exceptionally talented at making those but I've forgotten his name.

14 CFR 91.205 covers day VFR flight for U.S. aircraft with standard category airworthiness certification and all it says is that an airspeed indicator is required, period. So if it's good enough for standard category, it should certainly be good enough for experimentals. I suppose you could use a ...

Just for the heck of it and for studying where things are relative to one another with the plane in the straight and level position, I've attached a plot of a CAD layout that I did of a conventional Air Camper pretty much by the plans (no brakes; Ford A engine mount; vertical cabanes)- except that I ...
