Total Chaos (oz10364)
About this Plan
Total Chaos. RC pattern plane. Wingspan 65-1/2 in, wing area 699 sq in, for .60 engine.
Quote "We comissioned Mr Joe Bridi to design a new lite weight, low cost pattern and sports flyer. Utilizing the airfoil and wing design of the world renowned Curare (oz5527) pattern ship. The 'Total Chaos' is a real pleasure to fly, has excellent low speed handling characteristics."

Quote: "RCM Product Review. Hobby Barn TOTAL CHAOS.
The term Total Chaos refers to three things: (1) A club meeting when someone suggests increasing the dues, (2) this reviewer's pattern flying and (3) a new sport/pattern kit sold by Hobby Barn. It is manufactured for Hobby Barn by Model Aircraft Designs, 23625 Pineforest Lane, Harbor City, California 90710. The 37 x 6 x 3-1/2 inch box was completely filled with materials, allowing no opportunity for any shifting of pieces to cause damage. Accessories and small parts were separately bagged, the canopy was protectively wrapped in paper, and landing gear were also wrapped to prevent damage. All that was missing was a ribbon and bow.
Construction: Plans were on one sheet with 36 x 58 in dimensions and instructions covered six pages, one of which listed all materials in the kit. The instructions were sufficient to enable someone with some kit building experience to handle the job. This is not meant as criticism since this kit should only be flown by an experienced pilot.
All items in the kit were of excellent quality and the machine cut parts were accurately done. There are no die-cut parts and the entire construction is wood. Hardware includes an engine mount and all the usual nuts, screws, and gear. Elevator and rudder horns were 4-40 machine screws with a nylon connector that threads on the screw. The nylon connector accepts the clevis from the pushrods making an easy to install system.
The fuselage is a conventional balsa affair with lots of triangular reinforcement. A little shaping is required to attain the contoured look on the nose, but it is nothing that will keep you up late. The fin and rudder are 1/4 in balsa but the elevator and stabilizer are built up from strip stock. This is a little more work but really helps keep the total weight down. As noted later, this plane came out light and was actually nose heavy. The last time that we actually built something that turned out nose heavy, was a Honker with a Quadra on the firewall!
The wing was standard design with two balsa spars which provide the initial anchoring point for the ribs. This is the most critical step in the whole construction process as the wing is double taper and symmetrical. Once the ribs are home, slap on the sheeting, leading and trailing edges, and look for the sandpaper.
The basic construction job was four days of spare time from opening the box until sanding commenced. Pacer Zap-A-Gap and GMP 6-Minute epoxy were used throughout the project.
Covering: After a coat of Coverite Balsarite, an application of World Tex provided the outer layer. Dupont Centari enamel automotive paint was sprayed over the entire model. This white base coat was followed by red and blue trim using the same type of paint. The lettering on the vertical tail is vinyl stick-on letters.
Engine: An HB .61 PDP fit the engine mount so it was chosen to fill the cavity in the nose. Using the standard muffler, this combination provides plenty of thrust to make the Total Chaos perform. A Sullivan 12 ounce tank slipped into its compartment.
Radio: Futaba FGE 7 channel electronics were installed with no problems. Putting the three abreast fuselage servos as shown on the plan and mounting the aileron servo as deeply as possible in the wing is advised. The battery and receiver took their respective locations and it was off to the flying field.
Flying: The plane turned out nose heavy but was left there for the first few flights. With a total weight of 6 lb 3 oz, a wing loading of 20.4 oz/sq ft, a good performance was expected. These expectations were met completely; maybe our pattern flying will rise above the Total Chaos category with the help of this airplane. Landings are very easy, thanks to the low wing loading.
Conclusion: This kit is aimed at the sport/pattern flier and represents a good choice for someone desiring a kit of this type. The quality is excellent and construction goes along very well. Build it straight and you'll appreciate its characteristics in the air."

User commentsAre the wing rib templates available? They are not shown on the Curare 60 either. Thanks,

The Curare 60 (oz5527) has a supplement file that shows all wing ribs, all formers.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
