Dear Bill: It has been my custom to go by one of the local model shops to buy the latest Model Builder magazine when it com es out. I dropped by two of my favorite shops yester- ay and learned that both had sold their entire supply as soon as they were delivered (by the postman). Later. I called some of the other shops and learned that they too had sold out immediately to one man. This morning a custom delivery agent asked me to sign for a package. Upon opening the package I found a Model Builder magazine autographed in bold longhand by Bert Strieg- ler. Worse still, every place that Striegler's name appeared in the magazine was under­ lined in gold leaf. Apparently, the same thing happened to several other local modelers, and I expect modelers all over the country will be subjected to the same embarrass­ ment. I spoke to Beverly, Bed's wife, who said that Bert had bought up all the maga­ zines in Houston and surrounding cities. I haven't gotten into the article yet, but I was a little surprised that Bert was so for­ tunate. As I remember, the original used a Gene Thomas had some proportional divider trouble when he scaled up his "Civy B oy" from stabilizer and elevator from a Lil T. two arrows M AN plans, in the 1950's.

It only specifies that they must be done in the sequence listed. How­ ever, the direction of each maneuver is also specified. Therefore, if you take off from left-to-right, you have established that direction as "up­ wind" (whether it actually is or not). Once established, the rest of the maneuvers must be done in that relationship . . . upwind is left-to- right, and downwind is right-to-left. In this particular instance, the C.D. was correct, because, although the rules do not clearly state that se­ quence and direction are of equal importance, the intent is quite clear. Now then . . .

ROTOR RAMBLINGS One of our most popular R/C con­ struction projects was the Focke- Achgelis 61 autogyro (a real, wingless autogyro, not a conventional fixed- wing aircraft with a windmill on top) assigned by Skip Ruff, and published in the April 1975 issue (Plan No. Skip Ruff's FA-61, in slow, stable flight, is an easy target for a photographer. Ship has all the 4751, price $3.50). characteristics desired of a trainer. A true autogyro, it has no wings, depends entirely on rotors. Flaving flown the original model 14 MODEL BUILDER ourselves, we can vouch for its ex­ tremely stable and slightly different flight capabilities. Still, nothing has ever been developed that couldn't be improved on, and we have just re­ ceived the following changes and recommendations from Skip. They, along with the sketches, will be added to the full-size plans and article reprint for the benefit of future builders of this fascinating and out- of-the-rut aircraft. F.A.-61 M ODIFICATIONS AND RECOMMENDATIONS by Skip Ruff The following is a list of changes and recommendations for the FA-61 auto­ gyro. The latest model I built used the specifications listed here, and the model "flew off the board", so I highly recommend their use. No structural changes are needed.

If your model has a tipping tendency when on the ground, bend the main gear forward until there is very little weight on the nose wheel. Do all your test flying in dead-calm air, if possible, and make all takeoffs and landings straight into the wind. Once the rotors are set properly, don't be afraid to fiddle with the C.G., thrustline, or elevator inci­ dence, as you would a conventional This Quadra powered, quarter-scale Great Lakes 2 T-1 A , was built by Charlie Palermo, Houston model when making final trim adjust­ Texas.

It appears that Dragonflymania has hit Poway. We have three, evidence the pic­ tures, as of right now, with three more on the boards. The pictures were taken at the regular Sunday morning meeting of the Poway Pilots at their field. Once a month, they schedule a contest and each type of flight gets its chance; control line, free flight gas, then free, flight rubber, then RIC. There is a rule at the field that the engines may not be started before 9:00 a.m., so that gives everyone a chance to fly the rubber jobs and hand launched gliders before 9:00. The good thing about the club is its versatility, there is someone flying something different every Sunday.

Some, but not all, went onto starboard by gybing after weather mark, and generally an al­ most dead downwind parade resulted. Those lucky enough to be ahead of the pack were amazed at how much slow- ing occurred by the interaction of wind shadows on the run. Many fell below the rhumb line on the way to the leeward mark. Those boats that went high generally improved their position, since they got clearer air and moved faster to compensate for the slight extra distance to the mark. Rounding the leeward mark there was a general tendency to tack immedi­ ately (No. 5), and then not have enough of the lift to allow you to make the mark, requiring two more tacks (Nos. 6 and 7). In comparing the two tracks, we see that twice the number of tacks, and at least a 15% increase in distance can become a burden to a skipper who has not studied the course. Tnis would re­ quire a 15% increase in average speed to make up the deficit, and is just not to be found in any product on the market today. Let me say at the outset, as I have in the past, this kind of Monday morn­ ing skippering is easy, at least easier than doing it on the lake. But if the analysis helps us understand the sys­ tem, then it is worthwhile doing. Look at your lake and see if you don't see some similar situations.

I see by the Professional Pilot magazine that swept tip rotor blades are being studied at Langley. They are changing tip shapes and planforms to effect increases in rotor performance, and at the same time, decreases in the impulsive noise, vibration and struc­ tural loads of the blades. A few months back, Chopper Chatter included some preliminary data and photos on model R/C helicopter blades which showed much promise along those same lines.

(Western Asso­ ciated Modelers) members, Dave and Arleen Marshall, the idea became a reality. The writer, although having been exposed to control line for quite some time, was inexperienced at judging stunt. A few flights was all that was required to bring back the memories of what a good stunt pattern should be. Probably the most outstanding model on the field was a Yates "Mad­ man," originally built by J.C. "Mad­ man" Yates. It was beautifully finished in cream with red pin striping, and Bart Klapinski, the flyer, had no prob­ lems in winning the ignition stunt event. The running of the Orwick 65 in the Madman was sensational. Many a modeler standing on the outside of the circle was heard to say, "That When Sal Taibi packs a flight box for the Nationals, there isn't too much room left over. Here's is ignition!?"

Again, unfortunately, this event was the victim of poor publicity, as many modelers stated they would have en­ tered if the news had been made available. George Aldrich, the old stunt pro, was just hopping up and down on the sidelines, he was so turned on. When he found out the writer still had his old style Nobler (eligible under the rules), George said he would be back next year with a real ignition stunter.

Presently, Skip concentrates on RC sailplanes, but flies power "for relaxation." All in all, Skip is a generally happy individual and he's very athletic. He plays tennis and racquetball, skiis, and claims that all of this helps to sharpen his reactions. He doesn't practice RC soaring a lot, but does some mental exercise in preparation for this sport. As he sees it, RC soaring is still a challenge. He hasn't really had a chance to try aero­ batics yet, and hopes to take part in the RCM trophy race. It's only fair that he continue his interest in FAI contests and defend his title. Skip was edu­ cated as an aeronautical engineer, but has now turned to surveying.

These ranged from sleek modern craft to replicas of historic birds, such as the Baby Bowlus, by Bob Thacker, of San Clemente, California. That morning there were also two unofficial contests held at the same site. The first was for flying wing sail­ planes, CD'd by Dave Jones, of Los Angeles. The second was for electric- powered sailplanes, CD'd by Bob Boucher. In the first of these, there were a number of Ravens of dif­ ferent vintage.

I know for a fact that '77 was lousy for me, and I know exactly why. It was the Combat site. That one thing set my Nats off to a negative start and things seemed to go downhill from there. The smog, heat, wind and a bunch of other factors only made matters worse. By the Tuesday of Nats week, it was quite plain to me that I should have stayed home this year. I have absolutely no doubt that many people went to this year's Nats and had a great time. But a lot of us were aware of the many problems and went home disappointed. (And there were many who were aware of the prob­ lems, but still had a great time, wen) While at the Nats, there was a lot of discussion going on about how things were going and one of the most often proposed solutions was to have a split Nats for C/L only in the future.

With the exception of the very early airplanes by Curtiss and a few others, the W TA was one of the first aircraft to be equipped with tricycle landing gear, something that almost all modern general aviation aircraft have, for safer landings and ground handling. This aircraft was selected for a C 0 2 model for several reasons: 1. It is an historically significant airplane. 2. It has a reasonable free flight configuration.

In addition, the pod and boom ar­ rangement doesn't lend itself to the usual construction techniques.

But the story of the 1977 Nats Free Flight events is getting ahead of itself. The real first day of the meet was held at Norton AFB, in a large hangar. Norton was a few miles from Riverside, and provided an excellent location for an indoor contest. The scene inside the hangar was like this: Picture a 90 foot ceiling, steel covered and steel framed; beams and girders at the top, concrete floor on the bottom. Hanging down to around 60 feet were lights on cords and cables. The story was that they would be raised for the competition. That's the story.

The main landing gear wire, which becomes the axle, * STRICTLY - MARINE * is made to be pressed into and ce­ mented to the boom. It is inserted through the side braces as shown in the landing gear wire diagram. Struts and fairings for landing gear wires on this model were made from plastic tubing taken from old plastic drapes. Veteran's thrift shops provided a second-hand source. The tubing is approximately 3/32 round on the landing gear side braces, about 1/16 X 3/16 oval for the wing strugs, and two sizes as shown for the vertical landing gear leg. If such plastic tubing is not easily available, carve the fairings and struts from balsa sticks.
