I am going to open up the carb (stromberg) today and look things over. I have had three different carbs on and they all do the same thing. I have plenty of fuel flow to the carb, When I frst start it up it seems to get into the higher rpms which might be bowl gas but then dies unless I just idle.

Make sure the CG is not aft of 20 inches, and be carefull if the airplane is a short fuselage model with a lighter engine up front...usually these ships have the wing moved back, making the nose quite long, and usually the landing gear is covered, compounding the problem of too much area out front. Bernard never wanted us to cover the gear legs unless the airplane had a long fuselage, for better spin recovery.

Fiberglass gas tanks & Static Electricity Why not add a piece of stainless welding rod to your glass tank when you build it running from the low point to a spot a couple of inches from the filler cap so it would come through the covering? Label the end of the wire as the tank ground and clip to the protruding wire when you refuel (BEFORE you remove the cap!). On the plastic fuel cans I designed a grounding kit a few years ago that used an R/C model fuel stopper with a piece of stainless welding rod through it that was put through a hole drilled in the plastic can and tightened. The rubber stopper expands in the hole when you tighten the screw and the SS wire is submerged in the fuel. If the wire is bent so it goes close to the outlet hole it stays submerged when pouring. Just ground the can to the fuel tank ground and on to "earth" and you should be all set.

Fiberglass gas tanks & Static Electricity I've successfully dissipated and prevented static electricity in photographic labs for many years by mixing Downey Fabric Softener to water at a 50/50 mix, and then spraying carpeted areas in and around the lab. Here in the Southwest, on a cold-dry winter day, we can darned near arc weld with static after walking around on a dry surface and many rolls of films have been ruined when spooling film out of cassette in a darkroom. The static can bee seen on the film after development. The Downey/water method nearly eliminates the ionic charge, thus the reason your socks don't cling after coming out of the dryer when treated with Downey. (Ask any woman who wears nylon stockings... Downey is a must on man-made textiles.) When fueling my Cherokee in the boondocks, I've also used my "formula" for spraying down the surface of the wings, gas caps, my shoes and the area where I stand when transferring the gas, prior to fueling an airplane with plastic cans. (The cans are sprayed before fueling as well and allowed a minute or so to dry... The back of the vehicle is also sprayed before loading a plastic can! Try gassing an airplane at the landing strip in/at Wall Drug Store in South Dakota... ain't gonna happen unless you go into town for mogas. Also, Custer's Last Stand! No gas at the field, but a convenience store 1 mile away... Sorry, but sometimes remote fueling is an evil necessity for us who live and fly off of fields not having a fuel source, such as a ranch or in places in the Dakotas That's why I always carried my small spray bottle of Downy/Water in my airplane. I'm more concerned about fiberglass gas tanks in my Pietenpol though. Fiberglass makes for a great attractant for static electricity! I wonder if there is an additional way to enhance safety when adding gas to a wooden airplane having fiberglass tanks? I'm about to build my fiberglass gas tank and I thought of adding a small copper wire to the aluminum filler neck, then to the weldable flange, running the wire down to a low spot on the fuselage where I could connect to a ground source (probably a small copper shaft driven into the ground...) Obviously it's wise to AVOID using plastic cans for fueling an airplane, but sometimes we don't have a choice. Does anybody have any information about grounding tips and way to avoid static when fueling a wooden airplane having a fiberglass tank in the boondocks?

On secondary subject of long fuselages and CG's. I just completed the CG stuff on the rebuild of Piete N-1033B. This plane was built by Dick Greide back in 1979 and crashed in a MO cornfield in 1996 on the way back from Oshkosh, due to engine failure. Because the wings were off of an Aeronca 1300 payload, and Greide moved the wings back, longer 4130 fuselage, I decided to utilize the full advantage of this planes payload abilities by putting on an o-235 100 hp and shifting the CG as needed to fly my 280 lbs, plus wife's 130 lbs. Had to move the pilot's rudder petals forward about 4" due to 6'4" and long legs. It's a cozy fit by all measurement standards. Here's how the numbers came out: LE of wing used as datum point. 1) gear axles 2" 2) empty CG 5.5" with wt of 680# 3) fuel at negative 12" 4) tail wheel at 161" (had wt of 14 lbs when longerons level, min fuel, with full tank the bird will fall on nose without lead on tailwheel) 5) Passenger's front seat moment was 20" 6) Pilot's back seat moment was 53" Using 20% of chord as forward CG min. limit or 12" back from datum, and 33% of chord as aft loaded max. CG limit or 20". Trial (paper) loaded weight and balance came out as follows: 1) 170# passenger, 300# pilot, 120 # fuel. The initial takeoff CG was 17" behind LE, after burning off all but about 2 gal of fuel, CG moved back to 19". Both in the operational window, but wouldn't want to do a couple spins, pilot may wantta lose a couple Big Macs too.. Minimum pilot weight without supplimental weights in tail or baggage rack is about 150# with full fuel. This depends on the elevator's authority to hold the nose up during flare Max pilot weight with min. 2 fuel is about 305#. Moral of story, it is possible to build a fat boy's Piete, hope this info is helpful for the other couple non-FAA standard 170#'ers out there. Hope to be airborne next week or two.

CG limit or 20". Gordon, If I read you e-mail correctly, you have wings off of an Aronca on your Pietenpol. If this is true, then you CAN NOT use the 33% of chord as the aft loaded max. The 33% aft limit (or as BHP listed it as 1/3 of the wing chord), is for the Pietenpol Airfoil...not the Aronca Airfoil. You MUST use the CG range of the Aronca Airfoil, which probably has an aft limit of no more than 30%. Loading in an aft CG range is where you will be in serious trouble if you enter a spin. On several occasions I've seen Radio Controlled Model Planes spin all the way to the ground, because they were intentionally loaded with an aft CG, in an effort to attain a sensitive pitch control.

On Friday evening, I was doing some 'Smoke Runs' around Cook Airfield, and someone called the Fire Department, reporting a plane that was smoking, and going to crash. Luckily, two airport guys were there when the Fire Department showed up, and they pointed up at my plane as I flew past, and let them know about my smoke system.

But, the Aeronca has a straight constant chord of 60" like most of the storebought tail draggers, and a lot of tricycle geared planes. The limits of 33% of chord aft CG and 20% of chord forward CG limit has nothing to do with Pietes or Aeroncas, these are standard percentages used since the first Piper's and T-Crafts, due to the standard shape of the wing. Look at any oldtime builders book, use to be available from EAA bookstore, on how to build wooden homebuilt plane, these old books always used the 33% and 20% rule of thumb numbers due to the shape and chord of the wings they were building. Some designers recommended 32%, like the Osprey, others like Rutan had other numbers due to the sweep of wing and the constantly changing chord. For safety reasons, each homebuilder (aka Test Pilot), has to understand CG limits and how to safely experiment with their homebuilt wings and, if feasible, expand the safe CG envelope. The purpose of my prior email was to let a few of the other Big Mac challenged potential builders/lurkers know, it's possible to build a quasi-plans Piete that will safely handle their weights, if adequate attention is paid to placement of stuff that affect CG. Plus moving the wings LE back to approx. 18" behind the firewall. Gordon Bowen P.S. I stand corrected, I provided the approx. ARMS of the moveable stuff, not moment. Also N-1033B has a GM starter motor hanging out there by the prop and a 20lb battery between the passengers legs. ________________________________ Message 16 ____________________________________ Time: 03:29:33 PM PST US s=test1; d=earthlink.net; b=Y2Au5F419OpWnhC0KmtWNhdv6IUQK7vPk7uGV4zsXyRXfhJ6G22uFaoLiUavm4fW; From: "Dale Johnson" Subject: Re: Pietenpol-List: Glue question Hi Hjarrett you said the magic word { Lewis }.

Cy Galley EAA Safety Programs Editor Always looking for ideas and articles for EAA Sport Pilot ----- Original Message ----- From: Isablcorky@aol.com Subject: Pietenpol-List: Fuel cut-off valve Pieters, Am to relocate my fuel valve from under tank, center. Does anyone know of any rule, objection to locating this valve on the engine side of the firewall? give me your thoughts on this subject, please Corky Corky, I located my cable operated, 3/8" fuel shut-off ball valve on the engine side of the firewall, before I realized that certified aircraft must be located behind the firewall, for reasons stated by Cy. My reasoning was that I didn't want any fuel connections in the cockpit, where leaks could possibly develop. I now have a plan in the works to retrofit a stainless steel box enclosure, to capture the fuel shut-off valve, and carry a drain in the box overboard, to the belly. I cannot relocate the valve behind the firewall, because I built a blister in the tank outlet, to protrude thru the firewall, where the weldable fitting is glassed in. Any ideas about this retrofit would be greatly appreciated. This brings up another question about fire hazards...How much heat is required for Baby Oil to burn ? I have the fiberglass smoke tank located on the engine side of the firewall, however my exhaust pipes go down & aft slightly, totally outside the cowling.

But, the Aeronca has a straight constant chord of 60" like most of the storebought tail draggers, and a lot of tricycle geared planes. The limits of 33% of chord aft CG and 20% of chord forward CG limit has nothing to do with Pietes or Aeroncas, these are standard percentages used since the first Piper's and T-Crafts, due to the standard shape of the wing. Look at any oldtime builders book, use to be available from EAA bookstore, on how to build wooden homebuilt plane, these old books always used the 33% and 20% rule of thumb numbers due to the shape and chord of the wings they were building. Some designers recommended 32%, like the Osprey, others like Rutan had other numbers due to the sweep of wing and the constantly changing chord. For safety reasons, each homebuilder (aka Test Pilot), has to understand CG limits and how to safely experiment with their homebuilt wings and, if feasible, expand the safe CG envelope. Gordon, I wasn't aware of those other airfoils with 33% aft CG limits. I thought the Pietenpol's undercambered airfoil could get away with it, because of such a high negative pitching moment. A flat bottom airfoil does not have as much negative pitching moment (nose down) as an undercambered airfoil. Chuck G. p.s. the Wittman Tailwind has somewhat of a semi-semetrical airfoil, and has an aft CG limit of 28%. ________________________________ Message 20 ____________________________________ Time: 05:58:44 PM PST US s=s1024; d=yahoo.com; b=vSVgrHoMb89qzZNE6OPvq6GEbsCElzowQJWPy+Nnqjx11grnHno53le2WfhPVX+OaNU0gev+ALqM9rXU0Rezt2fy/eP4CvWXLx8/hv1HR+ptcdxOqku8v25P5JAY/woHMNN2HifDclHXK6HdeoaQFO0U5fS+UW68XWTDCR+6/FQ= ; From: Larry Nelson Subject: Re: Pietenpol-List: EAA website down?? --> Pietenpol-List message posted by: Larry Nelson Has anyone tried to log onto the EAA website this weekend?
