• This month’s maneuvers complete the entire program of maneuvers from Novice through Expert. There are seven "Figure 8" maneuvers in the AMA program and they all have one thing in common: the intersections are very easy to judge. The judge simply holds up a pencil, closes one eye and notes the first intersection by lining up the pencil tip held at arm's length. You, however, have to remember where that first intersection is and hit it each time. The judge clearly has the advantage here, unless you too have a pencil to watch. Impossible? Not at all. For years some fliers have used tray- mounted transmitters to give additional stability. Further, by using an antenna which can be adjusted to point to the center of the "frame.” they can refer to the antenna tip as a reference point. John Tapp from Salt Lake City.

A number of proposals have been submitted to clarify the definition of a Sport Scale model by deleting the statement “ Any model resembling a particular heavier-than-air, man-carry­ ing aircraft. . .” and substituting the definition found in the book on page 66. The reasoning developed out of the submission of models of aircraft that may not exist or have never been built. Not too many proposals concerned size this time, either engine or model. A couple of proposals did, however. For instance, one suggested that four-stroke engines should be allowed a greater displacement. Another suggested a graduated judging distance for models of different wingspans. For instance,0 to

CONSTRUCTION This model is built like an overgrown Peanut Scale model with a structure like the full-scale steel tube construction. The major fuselage material is 3/16 square spruce, which is strong, tough and not that much heavier than balsa. Even a quarter-scale version could be built with 1/4 square spruce with 1/8x1/4 stringers. It would be light but strong and durable. The only sheet material is in the front, to help support the firewall and a few gadgets. The forward bottom is a thick balsa block which is easier to shape and more durable than sheeting. Appropriate use is made of plywood for the firewall, a unique engine mount for the Wankel, bulkheads for the wing The section of the fuselage over the top wing is built with the wing clamped in place.

A simple jig was used to hold the wings in correct alignment while the struts were being fitted. This is a fussy, but most necessary procedure to assure true alignment. A quarter-scale version would need stronger strut con­ struction since they would be fully functional with the four removable wing panels. The fuel tank extends from the fire­ wall to back of the instrument panel. It is easy to look down through the wind­ shield to check the fuel in the tank. A streamlined Robart fitting on the upper right side aft of the cowling connects the tank fuel line through the fitting to the carburetor. Thus, the tank can be filled without disconnecting the fuel line at the carb. The radio switch andchargingjack are mounted on a ply panel on the left side above the lower wing leading edge.

This requires a special cord from the field box glow plug battery. (Come to think of it, my first control line model eons ago was wired like that.) The exhaust pipe for the Wankel was made from a brass tube bent to exit from a slot in the rear of the cowl. After many runs it is blackened just like the full-size stack. Although it was not possible to install the regular Wankel muffler inside the cowl, the long pipe plus the unique humming sound makes the Wankel quite tolerable, even to clubs with strict muffler rules.

An 11x4 painted black has worked nicely, too. A twelve-inch prop would be close to scale, but $1.00 landings get to you after a while! Since the Wankel has a 6mm shaft (0.236 in.) and props commonly have a 1 /4-inch hole, a brass bushing was made from tubing to slip on the prop shaft to accommodate the 1/4-inch prop holes. An exactly centered and balanced prop is essential, especially at the rpm turned by the Wankel. Wheel pants were optional on Wacos, but mine has flown from grass fields a lot, so no pants were fitted. The three- inch wheels are scale size. The engine cowling was fitted almost an inch aft of the scale position for access to the needle valve and for priming the carburetor, an essential procedure in the Wankel starting routine, which also requires an electric starter. The upper and lower ailerons are connected with DuBro ball link rods and fittings. After all, the full size planes Tail surfaces are built trom j /ö balsa, sanded to a streamlined cross-section.

18 R/C MODEL BUILDER Quadra engine opened ihe floodgates of giant modeling, of course. Thisengine started off as being an excellent, very economical entrance to giant modeling for virtually all of us, and it continues, much improved, to be unequalled in its class. It didn't lake very long, though, for planes to appear that were just plain too much for the Quadra, and for a long time this market went untapped. Now, however, there are beginning to be quite a few engines to fill these gaps, and they are almost universally very good products. The new Kawasaki engines, originally developed by Bob Siegelkoff of C.B. Associates, and now distributed by both Bob and EWH Enterprises, in both 2.6 and 3.14 cu. in., are earning the reputa­ tion of being fine, smooth-running engines. The Kioritz engine, at 2.44 cu. in., has had absolutely nothing but rave reviews from everyone I have talked to who is flying it.

The Hustler engine by EWH has been completely reworked to eliminate the vibration and electronic ignition prob­ lems it had originally, and reports say that it is one of the most powerful on the market. It is also very compact, making it a choice for tight installations such as on the Nosen Mustang. There are a couple of other engines around that I have not mentioned, but basically the supply of fine, excellent- running engines now completely fills our needs from the .60’s all the way up to the 3.7 cu. in. class. And, inside word has it that super-engines up to the 5 cu. in. class will shortly be introduced on the market, and at prices that will make them affordable. They won’t be cheap, but at least they will be available for those projects that just plain MUST have brute strength. On that last subject.

They were enthusiastic supporters when the International Miniature Air­ craft Association was formed in April 1980. Two of their members have be­ come officers of the new group: Corky Heitman is Vice-President and Tom Rausch is a Director. It was only natural that they would be selected to host the first IMAA sanctioned fly-in in the eastern part of the U.S. The IMAA meet format is pure fun-fly. No prizes, no trophies, no competition of any kind It’s certainly an idea whose time has come, and this pleasant, low- key type of activity is showing up in many phases of our hobby.

I first met Darrell and saw his plane at Toledo last April. At that time I wasn't very impressed, the plane seemed heavy and, frankly, the construction method hadn't really regis­ tered with me.

Actually, it isn’t as bad as that sounds. ROAR is small, much smaller than the AMA, for example, and has considerably less power in many areas, while also exerting more control in others. The problem seems to be that ROAR is still functioning about the way it did several year ago, before the big explosion took place, that of the 1/12 electric cars and all the racers attracted to R/C car racing by them. So Mike has a big job ahead of him, trying to bring ROAR up by its bootstraps, more able to meet the needs of today’s racers. One of the problems being faced now is what to do about keeping the bodies we use for racing from evolving into the wildly modified type of thing commonly seen in slot racing. Toward this end the new ROAR rulebook will likely contain a much stronger statement as to scale

If you have some tricky lettering to do, you can do it against a hard surface on a drawing board, right on a piece of the film painted the basic model color. It is a great way to decorate your scratch-built models when decals aren't available. How about instrument dial faces?

JANUARY 1981 47 • "The RAM Quickee 18 is a lot of fun.” There, in a nutshell, is theentirety ofthis review. But Bill Northrop probably would like me to amplify that statement a bit. so I guess I had better. This review actually covers three products: the RAM boat kit, the Hobby Shack "Aero Sport Two” radio system, and Cox’s newest engine, the R/C Bee .049. I am really pleased how these elements balanced out to a good work­ ing system. The boat is very quick to build, the radio system is inexpensive and works perfectly, and the stock engine features an extra large capacity tank, a throttle, and a muffler. All told, an inexpensive entry to both Boating PHOTOS BY AUTHOR and R/C. You can use both radio and engine in an aircraft, too. There are lots of reasons for building a boat. For some people, it is just the thing that they do. They would not be inter­ ested in an airplane or car. My own reasons were different, as I am primarily an airplane modeler.

R/C MODEL BUILDER 50 • Aiming to enter the prestigious MB P.P.P.P. contest, I looked, like lots of entrants, for an original and unpub­ lished model. After much searching, I decided on the P-T, quite a futuristic design for 1911. “ The pilot landed at 130 Km/hr. and he wasn't killed!” was the triumphal commentary of a contempo­ rary chronicler writing in the Aerophile. Rather than being inspired to build this plane based on that, I decided that the excellent layout of the plane, elliptical dihedral, and generous tail surfaces made it the perfect choice. Weight being the enemy, I used Micro-X indoor wood to help keep the tail as light as possible. It is highly PHOTOS BY BILL WARNER recommended that the builder of this model pay strict attention to keeping the tail light so as not to have to add weight to the nose for balance. FUSELAGE The fuselage is made up of three parts. The central body is made up of the “ keel and former” method (as illustrated in 1911 PAULHAN-TATIN the book Flying Models of WW-II). You will notice that the formers 6 through 10 are thinner. Small sections demand extra care and alignment. The paper covering Aero-Torpille No.1 will add a lot of strength later.

JANUARY 1981 53 indoor makes a nice change of pace from outdoor free flight, and the com­ petition can be just as keen inside This month’s column, then, will be slanted towards the indoor side of the hobby. P-24: THE WMC BEGINNER’S INDOOR EVENT My club, the Willamette Modelers, has for many years been holding indoor contests during the wet Northwest winters. As we gained experience, times climbed in the so-called “ beginners” rubber events we flew (EZ-B and Penny- plane) to the point that only the experts flew them. We devised an event de­ signed to attract newcomers to flying indoor rubber models, which is not too different from what EZ-B and Penny- plane were supposed to do. However, our beginners’ event seems to have really caught on, since P-24 is now rivaling HLG for popularity at our con­ tests. The key to this event is the rule that a commercial, unmodified plastic prop Bob White in earlier days, seen here launching must be used.

Here's his own account of his success (from Indoor News and Views, an absolute necessity for anybody inter­ ested in indoor models. Edited by Bud Tenny, Box 545, Richmond, TX 75080). "This plane was designed and built in the winter of 1977-78 for the specific purpose of making world record at­ tempts. Its success at breaking existing records (three world and three national to date) has been a surprise even to me. since I regarded it as sort of an interim design, an expanded version of my FAI ships. The primary reason for its excel­ lent performance is simply that its light wing loading of .0096 gm./sq. in. is less than that of any other competitive model ever built (at least insofar as my historical records indicate). Of course, the plane has a few other good charac­ teristics besides light weight. It is a pleasure to fly in still air with its slow motion operation, but its delicate struc­ ture and slowness are a detriment in the turbulence and drift of Akron. It took three days of determined effort to finally get one good flight up and down in one piece. By that time the plane was a patched-up mess. (Well, there were a few other flights one might call good . . . including one over 50 minutes . .. but these weren’t record breakers.) "Oh yes, the plane has ONE nasty trait.

Of the engines Dirty Dan mentions, the Picco 3.5 is the only engine the beginner could be truly competitive with by using it out of the box. It costs $200.00 and availability in large quanti­ ties is questionable. The OPS is next in line but will not run as fast as the Picco will stock, although it can be made to run faster than the Picco. Cost of the OPS is $120.00, add the rework and it too is about $200.00. Aside from possibly the K&Band Super Tigre, none of the other engines need to be considered as competitive. I speak from experience, having built several K&B, OPS, and Picco engines (or R/C cars.

Most modelers preferred to fly just one official, then have their models judged. This way the model is not apt to be damaged much as a result of flying. No scores were given to those who did not make at least one official. A board posted all of the scale scores or timing results, and were re­ corded by a most efficient crew soon after each happened.

Most radio problems are caused by poor installations, not interference. Although the reliability of my engines didn’t match that of the radio equip­ ment, it was very good.
