#35351 Gwaa sept v2 - Great War Aeroplanes Association
From Page 1– My dad didn’t like airplanes my son Phil, Jr. and his two year old Isabella. Al Cvelbar of Sharon, Pennsylvania built a Graham Lee Nieuport three years ago. He would call me three times a week and ask “You drill any holes yet?” Finally, in January 2009, I built a table, and Rick Bennett came down and helped me lay out one side of the fuselage on butcher paper. We started hack sawing, fish mouthing, drilling, and riveting tubes and gussets. Rick would come once a week and be a slave driver. He said he was easy compared to Robert Baslee. Marvin Story, on one of his trips east, helped rig the wings. The last year and a half went fast. When we got to the lower wings, I tried my hand at rib stitching. The Polyfiber book says “lacing.” (Fred Murrin thinks stitching is more masculine.) Every knot was different. On the main wings, we called the Queen of Stitching: Marsha Murphy (aka Fred Murrin’s beautiful blonde lady friend and the rhubarb pie winner at the fair). She and Fred knocked out each wing in about an hour and a half. I at least got the Sunrise pepperoni pizza and Diet Coke. I still owe Fred Black Velvet. The Tuesday before Gardner 2010, I scheduled the FAA examiner, Dean Glasser, from Pittsburgh. Until after Midnight, it was butt holes and elbows; Rick Bennett, Al Cvelbar, Bill Wonders, Fred Murrin (and I did do something—I just don’t remember what) lacing the front deck, getting the cowling to fit, transplanting the air cleaner, making the bottom pan, the top underwing pan, compass correction placard, etc. The next morning, Fred attached the ASI to the left strut, and Rick screwed on the cowling and attached the registration number and experimental decal just in time for Dean Glasser to start shining his little flashlight and go over his checklist. I paced like an expectant father. Rick sat in his bench seat removed from his van waxing eloquently on all Nieuport subjects. His completed masterpiece sat next to my newborn. Finally, after signing some papers, Dean ceremoniously handed me a pink slip (the good kind). There were pictures and congratulations GWAA 16 If You Are Interested In Reliving World War One Aviation For ‘The Great Times’ In Your Life Join the GWAA http://www.gwaero.com Sign Up Today An Events, Activities & Projects Centered Organization Volume 13, Issue 3 Fall 2010 THE ‘GREAT’ TIMES PRESIDENT’S MESSAGE Another Venue! Trailer Weenie Phil Arbie gets busy assembling his Baslee Nieupart after the 900 mile drive to Gardner. all around. It helped to have Rick Bennett, the chief engineer, there to let the FAA inspector know that he had successfully built his own Nieuport and had helped others. It may have also helped that Dean’s wife is Italian and that my plane’s paint scheme is Italian. As soon as the inspector left, it was time to take the newly certified, airworthy machine apart and stuff it in the new trailer (another story) and head for Gardner, Kansas. The first phase of the adventure was complete. Rick Bennett says it is just a pile of junk until I fly it. I have to fly it??? On Tuesday July 20, 2010, Rick’s wife had the rug hookers over (no jokes please) so he was free to make the timing adjustments. Now nothing left to do but fly or get off the pot. A lot of folks wanted to come and watch my first attempt. Why? I was scared 1) I would not have the guts to take off; 2) the plane would not fly; 3) I would crash on landing. I was freaking out and the audience would have amplified my terror. I told Rick the wind was too calm, the clouds too dark and weren’t there more adjustments needed? Of course I knew the answer. Do or Die; or maybe Do and Die. Oh well. Who wants to end up old in a nursing home, not knowing your name with your diaper full. While doing the run up I consulted Fred through Marsha “Do you think crow hopping or just going for it is better?” Fred agreed with me—“go for it.” Part of my theory is if you only get 20 feet off the ground you have to set up the landing in a hurry and you might be going too fast to keep the airplane straight. So I taxied real fast and straight and before I knew it I was climbing in a beautiful Italian replica Nieuport Biplane that 18 months ago was a pile of tubes. Wow. Like Dan Moadus, who built and flew his own legal eagle, said you will “think this was easy— what was I so afraid of?” What a thrill!— buzzing the airport in an open cockpit plane—it flies. Later after a good landing and a hotdog Rick rolled his Belgian Nieuport and we flew in formation. Then after 2 landings swerving in the high grass and the last one pretty straight, Fred held up a big card with a 1. He said .33 for all 3 landings. Marsha Murphy took the pictures. Hugs and handshakes and congratulations all around and celebration with a rootbeer and hangar talk. They say the first flight in your homebuilt is like the day you solo. Amen to that. If I knew it was going to go that good I would have wanted all the folks who wanted to come to be there. Happy Landings to all. Since 1996, the GWAA Dawn Patrol Rendezvous at The National Museum of The United States Air Force in Dayton, Ohio and the Gathering of Eagles in Gardner, Kansas have been the primary WW1 fly-in events in the U.S. But Jerry Yeagan in Virginia Beach, Virginia recently held the first of what will be an ongoing event for WW1 aircraft enthusiasts at his remarkable facility during the last weekend in September 2010. The Biplanes and Zeppelins Air show has become a new event for WW1 aviation enthusiasts to add to their calendar and with good reason. Your intrepid newsletter editor made the trip with his trusty Nieuport along with GWAA members Phil Arbie with his Nieuport and Rolland Gilliam with his full scale SE-5A. Rick will have a full report on his adventures in the next newsletter. This new venue, at which Jerry will hold a WW1 fly-in annually, is good news to our humble movement. It proves that interest in WW1 Aviation is on the rise and events such as this will help to attract new enthusiasts. Jerry has an impressive facility with two long turf runways from which he flies his collection of WW2-era aircraft, so it is ideal from which to fly WW1 aircraft. He is beginning to collect WW1 reproduction aircraft to add to his collection and is adamant about flying –Continued on Page 15 Phil Arbie’s N-23 on the flightline. Since Gardner, Phil has flown off his restriction and attended the Virginia Beach Air Show. My dad didn’t like airplanes By Phil Arbie My dad didn’t like airplanes. I have no idea why he let Uncle Willie take me up in a J-3 at Lyon’s grass strip when I was 10. Since 8th grade, I have wanted to be a bush pilot, and I wanted to build an airplane. I used to fantasize about being tiny and flying in a model airplane. After the army, I got a job at Packard Electric in Warren, Ohio. 9000 women building auto harnesses and a couple hundred men hanging wires. We were called service boys. That story for another time. I would drive by a grass strip with a weather beaten, rounded roof hanger with yellow Cubs parked out front. I started taking lessons with Ernie Hall, the oldest pilot in the United States. He knew the Wright Brothers and taught Jim Doolittle to fly. Fifteen minutes for $3.00. Four or five take offs and landings. I soloed with Ernie, and he put my name on a chalkboard. Through marriage, kids, college, career, farm, and politics, I managed to squeeze in a private license. Then, ten years ago, the money and the Citabria occurred simultaneously. On one venture to Greenville, PA, I saw Rick Bennett’s Nieuport and Fred Murrin’s Tri-Fokker. I was smitten with the WWI open cockpit bi-planes. Rick eagerly shared how he got started. Later, in 2005, I talked to Graham Lee in Canada and got his plans. Rick gave me a material list he had made up. My 1989 Dodge Pickup overheated on the way to Dillsburg to buy tubing. I turned around. Sometime later, Rick told me that Robert Baslee was offering a discounted kit to coincide with the Fly Boys movie. He said it would save a lot of time chasing parts. My paralegal Emily “borrowed” my credit card and ordered the Baslee kit. The 14’ box of parts lay in the garage for three years. Meanwhile, I settled a case and got the $2,300.00 for a Great Plains VW engine. I picked up the five boxes of parts on a trip to Omaha while visiting –Continued on Page 16 Building a WWI replica from someone’s kit or plans?....No More Using CAD From Page 1– By Jan Servaites (Kettering, OH) everything in his collection. These events serve a variety of useful purposes, one of which is to give builders a goal to work towards. One example is the Nieuport of Phil Arbie, whose early flights are also detailed elsewhere in this newsletter. His goal was to finish his airplane and fly off the 40 hour restriction in time to go to the Biplanes and Zeppelins Air Show. He made it not without a few bumps and bruises along the way. It was a good event and I’m sure it will continue to grow and hopefully all of you can make it a point to get to one of them. And hey, it’s Virginia Beach after all,… how tough can it be? Fred Murrin The purpose of this article is to discuss some of my ideas to design & build a 90% Albatros D-III replica. So, this isn’t a “kit” building article, but instead it’s a quick look at one of many ways to design one’s own WWI replica by stressing the use of an aircraft designer’s professional design tools. Maybe you are aware of the CAD engineering software out there and maybe you have seen the innovative, RC giant scale modelers using advanced engineering tools like CAD in their building of ?, 1/3, and now ? scale RC models. It’s very interesting to me to see these modelers applying some pretty high technical skills in the building of their high fidelity WWI models. But, I don’t see that level of effort in the man-flying WWI replicas. Are most replica projects built from kit/plans or scratch built to museum standards from factory drawings? Yes they mostly are, but I wanted to provide an example of one builder thinking outside-the-box to design & build a WWI replica. I wanted a subject that would be a difficult one to build and not seen much offered in plans & kits. I chose the Albatros D-III as the subject for my replica building effort. Here are a couple of points that I came up with, by observing the whole field of WWI replica building and flying for many years: Design layout – My philosophy (much the same as many others) is I want the external surfaces to resemble the real airplane as much as possible, so the original shape will dictate much of what goes on inside and affecting much of the President’s Message I have been very busy designing my own replica. Since I really like the N12 size (about 27' wing span), I am working on a 90% Albatros D.III with all aluminum wings (very similar to the N12's construction). The fuselage is a mixture of steel tube, wood & fiberglass. The powerplant will typically be a Suzuki 2.5L I6 (yes, I said inline 6), and it's all aluminum. If this works, it could be revolutionary. I'm currently designing the 3D fuselage shell in my CAD program. I did some CAD work on the wing and I made up a mockup of the wing rib. airplane’s performance (due to the drag of the biplane configuration, limited choices of engines, weight and general lack of streamlining). Good documentation will give the outside shape of the airplane. The 3-views from the Datafile publications and as well as detailed modern drawings based on LETTERS Good morning Mr. Bennett, I was very pleased to receive the latest GWAA newsletter in our mail box yesterday. You must be congratulated for an outstanding job with this one (as all of the issues before, I hasten to add). There sure is a lot of very interesting stuff going on, and coming up, and I appreciate your good efforts for keeping us informed. Now I do wish to ask a question, knowing full well that it is well over a year early : when we have attended the GWAA banquets at the AFM in the past, I have never quite known who, and when, to contact regarding the purchase of tickets. So could you kindly fill me in on the correct procedure so that I may be properly prepared for 2011 ?

From Page 2– No More Using CAD be a semi-monocoque, wood/fiberglass shell and welded steel tube sub-frame on the inside. The airfoil will be a NACA 4412 (12% thickness, Clmax of 1.5), so the wing spars will have a deep web for strength. Design layout vs. Design analysis – From a design analysis standpoint, your design requirements are used to estimate how big (full scale or some percentage scale) the aircraft should be, how big the wing should be, how big an engine should you buy. If you picked an engine, you’ll work backwards to determine what airplane capabilities you can hope to get out of it. How much will it weigh? What’s the stall speed? I’m not going to into specifics at this point, on ways to find those values, but I can recommend a very good comprehensive guide that simplifies aircraft design for homebuilders. It’s Daniel Raymer’s book titled simply enough as Simplified Aircraft Design For Homebuilders. He will show you simple math calculations to estimate sizing, performance and so on. I find it best to use an Excel Spreadsheet to do the design & analysis calculations, and he provides a complete spreadsheet file for you, so you don’t have write your own. Another good design guide is Donald Crawford’s book, A Practical Guide to Airplane Performance & Design. You can easily write a spreadsheet using Crawford’s equations & step-by-step analysis. The math is very elementary and he demonstrates the use of “nomograms” so the reader can immediately make valid performance calculations for his new design by connecting the parameter values with hand drawn lines (it’s a graphical technique). To start building a new aircraft design without any previous analysis in the final design is foolish, I think. Being overly ambitious into building could be a waste of money/time, especially if the engine has NOT even been selected, procured. Don’t put off thinking about the engine for sometime in the future. As I am writing this article my analysis is on-going, but my CAD work is pretty much done. Besides the CAD giving me precise body shapes, like fuselage station profiles, and wing tip/rudder/stab airfoils, it will also give me physical parameters GWAA 14 like surface area, volume and weight (selecting a body’s material could be aluminum, steel, plastic, wood, just about anything). It will also give the CG of a body, which will be very useful in modeling the balance of the airplane. All this can be known before any building is started. I have done some cockpit sizing using a CAD rendered pilot (a 95th percentile male) and the power plant that I’m going to use. All of the individual CAD “parts” (wing spars & ribs, rudder, fuselage, undercarriage, engine, pilot and so on) are then assembled into a CAD “assembly”. Now I can get the first impression of what my airplane will look like. I can actually see my airplane in 3D and I can view it from any angle. I can also get moment arm lengths and start doing some weight & moment calculations to find the airplane’s CG and its relation to the wing’s CP for stability concerns. All this information I can analyze and I can firm up my design before any metal is bent. Now, that’s cool. Structures – You have to define the overall concept and arrangement of the internal structure before one can design the actual “parts” of the airplane. A good structural arrangement is the provision of good “load paths”, and they are short, straight and continuous (not broken up in any way). Now, some professional CAD programs will perform load simulations on a structure (like an engine mount, the wing struts, a steel tube frame), by using what’s called “finite element analysis (FEA)” and I intend to do some FEA on the important structures. Cooling – I have seen a lot of examples of not-so-hot cooling systems in homebuilts and I guess these builders just didn’t understand the theory for a cooling system that really works. Being close to the propeller gives us turbulent flow and pulses if too close to it. So, where is the clean flow and high pressure on the aircraft? Simple, the wing!….and that is where Albatros originally placed the radiator in the D-III, and that’s were I will place mine. (For more information on cooling systems, go to www.ch601.org and look for “builder resources” link and then cooling systems; An article by Hans Mayer) Making it better - When designing the structures, there were a lot of guesses made, and its best to go back, and see if a redesign could make the craft lighter & stronger & simpler to build. As an example, instead of making the top wing in three pieces (the center wing section stays mounted on the cabanes), the wing will become two pieces with just one seam in the middle, and not two seams. It’s a lot simpler that way, and stronger too. Remember….build it light! Gone West Art Pearson, Kewanee, IL ,Nieuport 17 builder and pilot passed away on 6/23/10.

It looks great Butch, That was a great article, so was the 1903 Champagne any good? (Hey, I know you guys are having too much fun, so why are you guys frowning?) Jan Richard Bennett, Congratulations! Wow! What a fantastic job. Professional in every way. After reading it, front to back, and before filing it, I am proud to leave it on the coffee table for everyone to see. Keep up the great work. I plan to submit articles on our 'Tommy Come Home' project soon as we are now full speed ahead. ......................Don Funke Well, It's official! Tim doesn't like to brag, so I'll take the liberty of doing it for him... As of this afternoon, Tim is now a certified private pilot. He passed his check ride and verbal testing with flying colors, and is now on his way home to what will probably be his first good night's sleep in a while. Hope you don't mind me boasting on him a little, but I'm pretty proud of him. I think that Tim is living proof that if you want something bad enough, you won't let things like large hurdles and nearly impossible logistics keep you from your dreams. Good Job Tim!!! Wes Jones’s recently completed Sopwith Pup. Wes passed his FAA inspection, and has put the first few flights on in the beginning of October. Wes designed and built this airplane from scratch using Replicraft drawings. GWAA 4 Hey Rick. I received the copy of GWT yesterday. Thanks so much for sending that along and thanks especially for placing an ad for me in there. You've spurred me into finally joining GWAA, which is something I've meant to do for a LONG time but kept putting off. BTW, are you by any chance planning on attending the Fly-in at VA Beach in Sept.? cheers Russell Smith Studios GWAA 13 PROJECT PAGE Well, I couldn't resist to get Rick's trailer into CAD today (it took about 4 hours, I could do it in a lot less now. This was my first weldment). I got some more trimming to make it look nicer. If anyone wants a detailed drawing or whatever, I think I can provide it. There is also a cut list of all the 1" square tubes and the 3" channel. The top incline is 14 degrees by the way. To see if an airplane will fit, I would need a good side profile picture and dimensions of the airplane. I have taken Rick's plans to the next step in evolution, and rendered his trailer in CAD (SolidWorks Weldments). The CAD program will give me a "material cut list" of each member's length to be cut. Also, it can tell me the weight of the trailer as well as the CG of it. It's all very neat stuff. Also, I can resize the trailer to fit a larger airplane, and print out the 2D drawing and it's material cut list as well. Here is a picture of my CAD rendering, per his original drawing dimensions: www.janswerks.com/aircraft/trailer Jan Rick's words... It was built in ten days by two guys working part time. It works well to have one guy cutting with a chop saw and the other welding. All welding was done with a 110 volt, 110 amp MIG welder. Anyone attempting this project should check to make sure their model of aircraft will fit properly. Any of the dimensions could be changed to accommodate another type or scale. This trailer weighed in at 650 lbs empty, complete, and ready to travel. I have towed it 900 miles one way to Gardner with my Toyota Rav 4 with a 2 liter motor. A vehicle with a V6 would be a better choice. It tracks well on the road even in some pretty high winds. It does move around some when you are close to a semi truck, but nothing dangerous. Supplies needed are as follows; 1 ea) Axle with springs of the width to fit you frame (I had to cut mine and add 6" in the middle) 3 ea) Wheels and tires (Mine are 13" rims with trailer rated tires, don't forget the spare) 2 ea) Fenders 1 ea) Hitch to fit 2" tube 2 ea) Safety chains 1 ea) Light kit 30 Yds) Aircraft fabric (I used the heavy stuff) 2 ea) Rolls 2" aircraft fabric tape 1 gal) Water base contact glue (I used 3m Fastbond 30) 1 gal) Latex house paint 6 ea) Exterior plywood sheets, 3/8" 4 ea) Hinges for the rear door, 4" 4 ea) Hinges for the front and top doors, 3" 1 ea) Lift jack with wheel for the front (So you can move it around when disconnected from your tow vehicle) 2 qts) Varnish for the plywood GWAA 12 1 qt) Rusty red primer 1 qt) Gray enamel 8 ea) Bolts, for doors, 3/8" x 1 1/2" 2 ea) Bolts, grade 8 for safety chains, 3/8" x 1" 10 ea) Nuts, for above bolts, 3/8" 8 ea) 1 1/4" long pieces 3/8" ID steel tube, heavy wall, for bushings at door bolts 100 ea) Self tapping 1/4" x 3/4" countersunk flat head screws (For the plywood deck) Steel channel 3" x 2" x 1/8" for the main frame (Have this pressed by your local steel fab shop) 2 ea) 12' 4 ea) 66" 3 ea) 36" Steel tube 2" x 2" x 1/8" for the tongue 1 ea) 54" Steel tube 1" x 1" x 1/16" for the upper structure 300' (You may need extra for screw ups or if you change the overall dimensions) PROJECT PAGE Hello Al/Fred/Rick/Wes: Attached is a photo of the DH-4 as of July 10th. Making some progress. The cabane arrangement is a rough-cut temporary arrangement I put together to get me thinking about the final installation. Wes, you can see that I have it set-up as the Jenny plans show (top wing forward). Still a long way to go Rick: Hope the weekend has been good to you and the work is A-Okay now. Was a good "wood" weekend for old Bill. I got all my wood cut and rough formed (still need final sanding/finishing). Check out the attached photo. From L to R are my landing gear legs (still need to cut & form the bottom), front wing struts, rear wing struts, and cabane struts. Cannot believe that I was able to get them all through this stage over the weekend. This wood is very nice stuff. See you later this week. Bill GWAA 5 PROJECT PAGE The Airdrome Aeroplanes Sopwith F.1 Camel flew on 10 July after FAA airworthiness certification the day before. This flight culminated a build started in November 2009 following the Dayton Dawn Patrol event. Blake Thomas' Nieuport 28 was the performance goal (so formation could be flown), and test pilot Harvey Cleveland reports that the goals were met. Now for fellow builders, the nitty gritty. The Rotec R-3600 swinging a 90 x 48 Culver propeller, static rpm of 1750 rpm prop and 2650 engine - BIG CAVEAT - tachometer has not been double checked, but this almost exactly duplicates Ray Jarvis' R-3600 numbers with a similar propeller. While well down the 3600 engine rpm range, this produced a healthy 550 - 570 pounds of thrust. I feel pretty strongly that once broken in, and perhaps other tweaking, it will easily reach 600 pounds of thrust. With two electronic ignitions, it starts instantly. The throttle body injector is its own entity, and we are learning how to best use it. I STRONGLY feel it is superior to the stock supplied 40mm Bing carb. based on my limited experience so far. One trhing you do notice is that the Rotec 9 cylinder is much quieter than you expect, and very smooth. From the ground, vintage aviation author Eric Preston said it sounded much like a 80 hp LeRhone in the air. The cockpit was bone stock Sopwith, with many original 90 yeaqr old instruments such as a compass, watch and altimeter that were original Camel equipment. Most every other instrument, control stick, throttle quadrant and others were exact reproductions of the original item. The Sopwith currently has provisions for brakes, but not hooked up. At just over 1100 pounds test AUW, it is no little light airplane and has some serious inertia to be managed on the ground. This test was on grass, but it will absolutely need brakes on any prepared surface. The steering tailwheel was wonderfully positive, and at least for us frequent flyers, a very neccesary compromise. On take off roll, not pushing the plane at all, the tail comes up smartly and the plane unsticks in about 400 feet. Climb out seems happy at 60 or so mph. We did not push the climb, but a normal climb rate of about 600 or so feet a minute was what it seemed. All of the controls were not neck jerking, but positive. One thing that impressed the test pilot the was the wide speed envelope of the airplane where no trim was needed; you just put it there and it stayed. I personally think this is probably attributable to the original Sopwith designers' mass concentration. For you technical folks, we have 1.5 degree wing AOI with 0 degree horizontal stab AOI, lower wing dihedral of 5 degrees and zero degrees for the top wing. The engine has a down thrust of 2 degrees. The test CG was about 24% MAC. Controls were described a sweetly harmonized and normal stick pressures - seems Sopwith got their control surface areas dead nuts on. Slips wonderfully. Did not do a full stall series this flight. At reduced power settings, the airplane would fly happily loafing between 80 - 90 mph at 1650 rpm indicated Lower the nose wee bit at same settings and it would easily pick up to 100 mph indicated. Again - these are indicated and not verified against an external source, but it was a new ASI. Approach was tried at 70 and 80 mph, both worked fine. When the power is pulled, the plane does not slow as fast as you think it might (inertia), bur settles gently down to the runway conventionally. Without brakes or skid, it had a loooong roll out (inertia) of about 1000 feet. Many thanks to Robert Baslee and the Airdrome team, Harvey Cleveland. We actually had a camera ship with noted author Eric Preston on board, and here are a couple of photos. I think it's the best looking Camel replica flying, but I'm biased.

I built the SE5a from a set of Replica Plans some 36 years ago. (I love biplanes) As there were no plans for the Albatros as a microlight I had to dream some up. I have no qualifications in this field having been a salesman and businessman (now retired) The tricky part was to construct the semi-monocoque fuselage, the originals being built of birch ply. To overcome the double curve I used the boat building system of carvel planking, which worked fine. After some initial modifications and adjustments it now flies hands off at cruise revs. 7 hours have been flown to date. It is powered by a Toyota 4AGE 1600 fuel injected 120hp engine with a cog belt redrive of 2.57:1 ratio with a 78 - 56 prop. The maximum speed is 80 mph at 5250 engine revs, cruise 75 mph at 4500 revs. It stalls at 40 mph and at take off you feel the back of the seat. Empty weight is 870 lbs. This project was completed with the help and advice of many people who have enabled me to accomplish this dream. Come visit New Zealand - perhaps we can have a dog fight! Plans could be available after 40 hours has been completed, providing I have not exceeded my life span, just now 82. From New Zealand GWAA 10 PROJECT PAGE Dear Rick, Thanks so much for sending me the copy of GWAA’s “The ‘Great’ Times. I found Fred Murrin’s article about the Sopwith Pup particularly interesting, and the photos were fascinating. It looked to me like the “Pup” designers had solved the problem of lateral stability on landing that Nieuport 11’s seem to have, by moving the main gear slightly aft - as some N-11 folks have been doing. I got started building my experimental version N-11 with plans #549 shortly after I retired over a decade ago - had a close relationship with Graham Lee, and worked hard on it for a couple of years, long enough to get serious about an engine. I did lots of research, looking for a four stroker, and finally settled on HCI’s 65 hp radial, which I’d seen and heard run (very briefly) at Sun-N-Fun. I contracted with Jack Hereford to build me one and by the time they delivered it, they had enlarged the cylinders to get 75 hp, which Graham said was to much power. In the meantime, it turned out that they were having trouble with vaporized fuel condensing in the lower intake tubes and began experimenting with various ways to resolve that problem. The result was that I got discouraged and lost interest in the project. That coupled with going back to work full-time cost me a bunch of construction years. I finally got back into construction and have completed everything except covering the two halves of the lower wing, and the fuselage, and doing the camouflaging that I’ve spent a lot of time trying to do accurately with th four basic greens and browns Alan Toelle has determined to be authentic. Long Story, short point: A now-old, former F-86 Korean War fighter pilot who’s interested in punching some holes in the air again, is grinding out completion with hopes of maybe flying another fighter of another era! We’ll see. I’ve always thought that Don Chihocki did the best job of replicating Graham’s plans, and that you and Ted Callahan have done the best jobs of replicating the experimental version. Anyway, thanks for sending me the copy of The ‘Great’ Times, which I enjoyed reading. James k. Thompson GWAA 7 Gardner 2010 Fly-in Observations … Bill Wonders displayed his Dh4 fuselage at Gardner. Bill trucked in from Burton, Ohio. Great fun! The Gardner, Kansas “Gathering of Eagles”, 2010 was my first visit to Gardner and it proved to be more than anticipated. I’ve seen photographs of past Gardner fly-ins and talked to pilots who have attended however being there in person brought the event to life. As a first-time attendee, I thought I’d share a few observations: Getting ready for the event was a challenge for any pilot hauling an aircraft to Kansas and even proved to be a work-challenge for Rick Bennett. In addition to getting his own Nieuport packed and ready he helped Phil Arbie complete building his Nieuport, then they built a trailer (from scratch) to haul the finished plane to Kansas. To complete these monumental tasks on time Rick had to kick in a twenty-eight hour/day schedule and work non-stop … he’s like a perpetual motion machine with an unmatched work ethic. I get tired just watching Rick work. Yes, everything was done on time, Phil’s plane and trailer both looked great. Fly-in preparations at the Gardner Airport also carried demands for work and time. Marvin Story and his wife, Nancy, certainly rose to the occasion making sure event requirements were completed and everything moved smoothly. It was generous of Marvin to share his hanger too as it became the meeting place for all GWAA attendees. Pilots used Marvin’s hanger (and tools) for airplane assembly and disassembly plus the hanger came in handy when a major rain storm hit on Saturday. The rain storm did not disrupt activity for long and pilots were soon back Mark Hymer’s Baslee Fokker D7 gets a close inspection from the Gardner crowd. GWAA 8 Butch and Rick Witlock managed the cooking for the Friday evening barbeque. Saturday afternoon a fast moving front rolled thru Gardner and sent us all looking for our tie downs. in the air. I’m told rain storms and high winds are common at Gardner events. That area of Kansas records an average wind speed of over 12 mph, that’s: AVERAGE WIND SPEED! I observed the Kansas Dawn Patrol pilots taking those high winds in stride … guess they’re used to it! Marvin’s hanger also served as a dinner meeting spot on Saturday where Butch Whitlock did an excellent job serving as GWAA’s head-chef. The Gardner Fly-in included a visit to the WWI Museum in Kansas City, a visit that proved to be a terrific learning experience. The museum was outstanding with exhibits that were truly educational. Learning experiences also came from the many GWAA Pilots who were willing to share ideas on airplane construction, flying replicas, and history about their machines in combat. My final observation was on the GWAA Pilots. Interesting, to me, that they all displayed the same strength of character, the same dogged determination, and the same excitement for flight as, I believe, pilots did in The Great War. I look forward to attending “The Gathering of Eagles” 2011. Bill Wonders What the hell was going on in this photo . . . ??? Were you crapping your pants? dickiedoo Hey everyone, This was the 1st year for me to visit Gardner. I've yet to fly, and yet to build, but I've been hovering in the background for almost 2 years, listening to the conversations, reading nearly every post. If I had any doubt as to my fit with such a group, that vanished with the 1st conversation. What a great group of people! On Friday, it was set-up and staging day. I met Sharon Starks, Tom Glaeser, (the rest of the group had run to the WWI museum), and I just wandered, getting use to these planes. But Saturday, I got locked into so many different conversations, I forgot to shoot and film, hell, I bought a camera just for the event. Russ even invited me out to Roberts to sit in his Camel... I'm not quite sure if I'm ready to drink the koolaid yet, but you guys had me grinning from ear to ear. –Continued on Page 11 Phil Arbie trailered in his Baslee 7/8 scale N-23 from Ohio to display at Gardner.
