March and April - Senior Pattern Association
The SENIOR PATTERN ASSOCIATION News Letter Bruce Underwood - President Tom Atkins-Vice President Steve Byrum-Secretary Treasurer Mickey Walker-Past President Jeff Hannah-Appointed Member Jim Ivey-Chairman Special Projects Ed Hartley-Web Site—Newsletter Editor Frank Stewart-Appointed Member Volume 11 Number 2 Ron Reed—Past President WEB SITE-http://www.rcpattern.net/spa/spa.asp March-April 2001 Senior Pattern Association - Simply Better THE PRESIDENTS PERSPECTIVE March and April..... tradition among modelists that this is the season for completing the winter projects just in time to have them ready for "trimming" when the weather breaks. Ironically, we in North Alabama had a beautiful week-end the last one in February and thanks to the "top-off" charge feature on the accu-cycle.....we were ready with hot nicads to take advantage of the nice couple of days...hope you were also. Steve, Jim, Mickey, Frank and myself visited one week-end in late January with Troy Emmett and several members of the Floyd County, GA RC Flyers at their nice facility, Rose Memorial Field in Cave Springs. As a result of our fellowship with those nice folks, they were kind enough to invite Tom, Malcolm and Scotty to their February club meeting in Rome and plans are being finalized as you read this for us to hold an organized SPA contest hosted by the Rome club. Jim Ivey, CSP, says it will probably be prior to the Masters, perhaps in August. I'm sure Tom will cover the meeting in detail in his column. We welcome Floyd County, GA to our growing list of organized contest activity. Ed Kirtley up in Bowling Green, KY says we'll more than likely be visiting his club there and contesting this season. Dr. Charles G. Gray SPA # 156 says details are forthcoming on the initial SPA contest in Terre Haute, Indiana. It is so comforting to see Pattern RC enthusiasts in other parts of the country actively stirring SPA interest in their locales. We, in the Association front office will do whatever we can to assist.... just let us know. Steve has printed numerous "Info-packets" which were passed out to visitors to the SPA booth at the SE Trade Show in Perry, GA, (more on this from other authors)...and these are available for downloading from the SPA website....or if you don't use computers, just write Steve and ask for them...we'll be glad to accommodate. The new GUIDELINES and RULES manuals are a good deal larger and will be available at the initial contest. It is hoped that competitors will pick them up in person because the size, weight and expense of mailing them is almost prohibitive...however, if you request them....we'll be glad to oblige by return mail. I am aware that only a small percentage of our membership uses computers as do all our Board members consequently do not have access to the patterns for this season. For that reason, copies of the patterns are included in this issue of the newsletter. More and more availability of plans, kits and short kits of SPA eligible airplanes are being uncovered, some advertised in this newsletter, other info can be had from the SPA website at: www.rcpattern.net/spa/spa.asp CD's...be advised that Ed (our webmaster) has even made available score sheets for downloading from the website. If you have access to the website and have the printer and facilities for printing these and aware of our members who don't use computers.... would you be kind enough to print them a few copies and get them to them. That would be a genuinely nice gesture on your part. TALL TALE stories continue to "trickle-in".… I look forward to sharing them with you! Just think, the next issue will contain results from the seasons' initial contest in Cullman. Let's go practice. See ya' on the circuit.

Cass Underwood Top Notch Trophies Guntersville, AL 35976 (256)582-0606 From The Chairman Of The Board Boy, as I write this I am just beginning to get a slow down from the computer. Since the article by Eric Henderson in Model Aviation Magazine. I have been on the computer every night replying to email request about the SPA. This has really given us a shot in the arm. People from all over the country have responded. The thing I find interesting is old pattern flyers are out there just like they are here, they just need some one to get them together in their area. It should be easy enough even if a given area has only six or eight to start with. They could have a fun fly using SPA legal models until they have enough interest to have a contest. But it seems hard to find that one person to get it started. Well we only have a few weeks until our season opener at Cullman, I sure hope I can get out and do some flying soon. Due to surgery the weather and every thing else I find I have not flown since the masters. I have not even tried the new maneuvers. I told our editor what a good job he is doing on the news Letter. I was really impressed with the first one. I just returned from the Perry Ga. Swap meet and was very impressed with the SPA booth. I did not get to spend as much time there as I would have liked, but there were a lot of our members there and Steve was doing his usual good job. I am sorry I did not get to help man the booth but I had to make the rounds of all the other things I am involved in. That's the price you pay for being involved in so many different Parts of this great sport. As most know the show has booths for the society of Antique Modelers, Model Engine Collectors Assn., Thermal Thumbers Free flight club, all of which I am a member, and I have a life time of friends with all of them. Boy ain't this a wonderful sport! Mickey WHEEL PANTS OR NOT! About strut and wheel pant aerodynamics. A wire has much more drag than a faired strut and wheel pants produce less drag than a wheel hanging out in the breeze. This is just basic aerodynamics. Back when I was a young whipper snapper starting my career as an aerodynamicist, there was a book that we referred to, by a guy named Hoerner. The book shows drag for just about every practical shape possible, airplanes, cars and components thereof. It was from the late 1950's. I looked it up on the internet at a used book place "alibris.com" and was shocked to find a $220 sticker. I wish that I had held on to my old book. Any way it was a standard reference back then and confirms all that we have said about DRAG. Read on there's more. There are other aerodynamic factors to consider. The gear contributes to STABILITY / INSTABILITY & TRIM on all three axes, pitch, roll and yaw, pant or pant less. Anything that you stick out in the air stream affects the overall aerodynamic package. For starters, anything that is placed forward of the c.g. is destabilizing in pitch and yaw and anything aft of the c.g. is stabilizing. Roll stability and trim are not likely to be significantly affected. The gear part of overall aerodynamics is generally much smaller than major components such as the wing, horizontal stab, vertical stab, and the overall fuselage. Generally, the gear effect may crop up in the yaw/roll coupling of the airplane requiring some mixing to get nice knife-edge flight. In fact for older aircraft such as the DR this may be required, regardless of what gear configuration that you use. Gear affects aerodynamics as follows: For a tail dragger the main gear is forward of the c.g. and therefore is destabilizing in yaw in that it counters the stabilizing moment of the vertical fin. It also provides a rolling moment opposite to that of the vertical fin. In case of tricycle gear you have to look at all three "thingees" hanging down in the breeze. The nose gear is very forward of the c.g. while the mains are aft of the c.g. but all three unbalance the aircraft roll-wise in knife edge flight. So, depending on the vertical stab/rudder design, it could be better or worse off with whatever gear configuration that you choose. You can't tell until you do it. I would suggest go with your heart and whatever you fancy, then dial in some mixing to account for any configuration shortcomings. Just thought some of you might be interested in this little tid bit. The above is by no means a comprehensive analysis.

Many of them are not on the SPA approved list, but the necessary documentation is here. I have put this together from my collection of old magazines, and was amazed at how many there were, even though I don't have several that are listed by SPA. The copies are a good way of checking out what designs look like. You can also enlarge the plans so they are fully usable, by the usual photo-enlargement or scanning. I can send copies by airmail at a price of US$5 for every two designs ordered . Please send currency (bills) only, because checks are too expensive to clear from New Zealand. Address: Wayne Cartwright PO Box 946-Pukeko-Auckland New Zealand Email: j-w.cartwright@clear.net.nz Note that the Blue Angel is available only as a full size plan. The price of this is US$20 including airmail. I would also like to obtain copies of designs that I don't have, on a swap basis. 1965 Thru 1975 Model Atlas Banshee Blue Angel Cajun Queen Configurator Crusader Cutlass Cutlass Supreme Daddy Rabbit I Dirty Birdy and kit from Bridi El Tigre Eyeball II Intruder Kaos King Altair Kwik Fli II Kwik Fli III Designer Matt Martin Yoshioka/Kato Penrod Buso Brooke Coleman Coleman Whitley Bridi Country Leichtenstein USA Japan USA USA USA USA USA USA USA Magazine RCM&E FM --AAM AAM MAN MAN kit MAN RCM Donohue Schroeder Kirkland Bridi Husak Kraft Kraft USA USA USA USA USA USA USA AAM MAN MAN RCM RCM RCM MAN Mach I Miss Norway Mr. Ed IV Panzer D20 Page Totland Brothers Brand USA Norway USA South Africa MAN RCM RCM MAN Pegasus Phantom 1 Phoenix I Phoenix 5 Slik Fli Striker Sun Fli 3 Super Kaos Superstar II Tiger Panzer Tiger Tail Wilmot Klineyoung Lowe Lowe Kraft Russell Bridi Bridi Matt Bland Chidgey USA USA USA USA USA England USA USA Leichtenstein South Africa USA RCM RCM RCM AAM RCM&E RCM&E RCM RCM RCM&E RCM RCM&E USA USA USA USA USA USA USA USA USA USA USA RCM&E RCM FM AAM MAN MAN RCM MAN AAM AAM RCM&E Comments World Champion 1975 Full size plans available from FM World Champ 1973; full size plans Developed from Intruder Full size plans available from MAN Full size plans available from MAN Full size plans available from RCM Full size plans available from MAN Influential design Full size plans available from RCM Full size plans available from RCM Full size plans available from RCM World Champion 1967.

I stumbled across the SPA Website several months ago and being a sport kind of RC pilot, it really caught my interest. I posted a question..."Where do I find Daddy-Rabbit pictures on the web"? That one query was all it took....I had a flurry of replies, the first came from Ken Blackwell in Enterprise, AL. Not only a photo but loads of general information. A night or two later, Bruce Underwood E-Mailed me suggesting I become an SPA member and join the fun even though I am long-distance from the hub of competition activity. He convinced me to ship 20 bucks and application which yielded my membership card, etc. in just a few days. He "slick-tongued" me into voting for him rather than "write-in" for President. After studying results I decided on starting with a Zimpro DR short kit...my dad used to say..."blaze new trails only after you have walked ones well traveled". Excellent decision considering I had only built sport planes prior, no pattern ones. As I progressed with the assembly, I would post questions on the SPA mail list...and "bang" there would come how to input right back. Not only did I receive useful info, I got a few "witty" sentences (usually from you-know-who) that turned my frustration into a smile...or at least a giggle. As a believer that "Wings" make airplanes fly, I was pleased that designer Jim Whitley incorporated a big wing on the DR. He is a guy after my own heart....big wings. (Ed note: Whitley's hands and feet are too).. I opted for a one-piece wing which I mounted using a single 5/16th dowel in front and two 1/4- 20 nylon bolts in the rear. I intend to use an OS-91 4S for power. Found one from a friend for $180.00. I will use a 16 oz. DuBro tank unless a problem with draw develops and I will then solve RCM RCM&E AAM AAM MAN RCM&E AAM Full size plans available from Qualified for 1963 World Champs Full size plans available from John Pond Plans Qualified for World Champs that with a 12 Oz. one with 4 Oz. "hopper". Most mounted the OS sideways to assist fuel-draw, I will do same. The prop recommended was an APC 12 1/2 x 10. Since my engine is non-pumped I'll use a standard Dave Brown FS 90 Mount. I'll use 2 1/2 or 2 3/4" wheels as mains with maybe 1/4' smaller on the nose as it's gonna be trike gear. I like tricycle since it ground handles better in the Idaho wind. I got a lot of help with the gear assembly as the block-embedding method was new to me. I found the use of polyurethane glues ideal for this...careful to clamp pieces preventing the formation of tiny bubbles consistent with this type adhesive. I really got the response when I asked about finishing. Consensus is Monokote...however I love silk span and Dope and will use that as it rekindles memories of its' past use. Final assembly of the Zimpro DR short kit is a breeze...the wings & stab were pre-sheeted...I just built fin & fuselage from the provided plans. Excellent quality. A note to less experienced builders...should you encounter any difficulty assembling SPA eligible airplanes......just post HELP on the SPA mail list...you'll get plenty. SPA, as an organization, provided me with more help than I ever imagined. Mike Riggs SPA178 Boise, ID From Our Fearless Treasurer January and February have been really busy for the SPA. Since Eric Henderson featured us in his Model Aviation column, Mickey and I have handled a steady stream of inquiries. Averaging about a half dozen each week, we have sent SPA information packets all over the country, and to several foreign countries. It would seem that Mickey touched a bigger nerve than ever imagined when he founded SPA ten years ago. There is much overseas interest in non-turnaround pattern. As recently as this week, we've sent information to New Zealand. We've gained about a dozen new members since the first of the year. Hannu Riihela of Lahti, Finland is our first foreign member. Pamela Sappington, Clinton, IN is our first female member. As nearly as I can tell, John Gausby, Glen Allen, VA, Dave Willis, Sevierville, TN, Harvey Barnett, Port Orange, FL, Jeff Tarlton, Malvern, AR, Edward Csanady, Brighton, MI, and Richard Forbes, Miss. State, MS all found SPA as a result of the Henderson article. This was my first experience with the Perry, GA swap meet. I was very pleased with the efforts of our members. There were almost two dozen SPA members present. Nearly all took their turn manning the table. I shared the table with new member Harvey Barnett for most of the first two hours. After that, guys just showed up and stayed a while. No one had to stay too long, but everyone did his share. We had planes from Jim Ivey, John Baxter and Ron Reed. Aztec Airplane Factory, owned by George Truett of Chiefland, FL donated a brand new Jim Kirkland Intruder kit for a raffle on which SPA netted $110. During the afternoon, Tom Atkins and I cornered AMA District Vice-president Jim McNeil. Jim is proud that he was able to help SPA gain its Special Interest Group status. If his camera survives, you may even see Tom and I in an upcoming issue of Model Aviation. I am in the early stages of organizing an SPA library. Included will be copies of as many plane plans as I can get copies of. I am very concerned that the various plans services may discontinue offering older style planes, and may dispose of plans they feel they no longer have a market for. I'll publish a list of the plans I already have, or have access to. Mickey and Frank have both given me lists of what they have. Sid Austin is going to allow me access to both his and Dick's plans, also. The majority of the plans I have now were forwarded to me by Dennis Hunt out of Jim Jones' estate. As plans are requested, I'll have copies made and mailed at whatever the actual cost is. The few I've sent out so far have cost $8-12 including postage. After posting the list, please let me know what other plans you may have which are currently approved. Also, any documentation on planes of our era, which is not on the approved list, would be appreciated. Steve Byrum SPA EXPERT 1. TAKEOFF (U) (DOWNWIND TRIM PASS) 2.

From The Vice President Hello SPAers, As a charter member of the SPA, I have wondered what the future holds for us for some time now. There have been times when growth seemed very slow to nonexistent. This was a curiosity to me, but nothing that I worried about very much. I have always believed that our event would catch on and show explosive growth, but if it didn't and things stayed as they have been for the past three or four years, it was still the best thing going. I am convinced by recent events that SPA is reaching the explosive growth stage of development. The publishers of the magazines are beginning to pay some attention to us, the folks I meet at various functions know who we are, and are enthusiastic, and Mickey (Super Hacker) Walker tells me that e-mail from interested parties is at an all-time high. I see nothing but positive development for the future. Scotty Barland, Malcolm Rutledge and I visited the Floyd County club during one of their meetings to discuss the possibility of their holding an SPA contest. I fully expected that a decision would be made at some time in the future. These guys are my kind of people! They voted to have the SPA contest the same night! Way to go Floyd County! The three of us who were there for the meeting have agreed to fly with the Floyd County flyers to help them get ready for the contest. I am looking forward to the experience. If others could do the same, I am sure that the effort would be appreciated. My airplane for this year's campaign is coming along pretty well, but never fast enough. By the end of this weekend I hope to have it primed. Things never seem to go as quickly as I would like, but the thought of my being in a hurry is too horrible to contemplate. I have talked to Mickey about plans for SPA legal airplanes recently. I realize that there are still quite a few plans available, but if someone has a set of plans that are not now available, I will draw them in AutoCAD so we will have them for the future. Let me know. This is a time consuming effort, and it will not happen overnight, but I will do them as quickly as possible. Marty Barry and I have been doing some research on 2-cycle engines and mufflers. For those of you who still like the 2-strokers there is reason for some excitement. We have tested various readily available mufflers and found that the Performance Specialties units will give you the same RPM as an open exhaust and do a decent job of muffling in the process. On our YS side exhaust engines we are getting 11,300 RPM with an APC 12x10 prop. I believe that this combination will be UNBELIEVEABLE on my 7 lb. T-2-A. The OS 91 4-strokers have had a decided torque advantage over their 2-stroke 61 brothers, and I believe that a combination similar to this will help close the gap. I also believe that more choices will be good for the event. It will be interesting to see how these things develop during the next year or so. I look forward to seeing everyone at the contests this season. There is no greater group on the planet. This will undoubtedly be the best season yet.
