Quote: "This rubber powered ROG has the flavor of a French Antoinette. It flys fine. AM/FM by Bill Hannan.

Remember the movie 'Those Magnificent Men in Their Flying Machines'? My favorite scene was the graceful Antoinette gently landing on the narrow English country road, to the astonishment of an elderly couple in their vintage auto. The motion picture aircraft was based upon the classic French pioneer Antoinettes of the 1909 era, which were very advanced for their time, particularly when compared with the biplanes against which they competed.

Although our little AM/FM is quite basic, we have tried to incorporate some of the "flavor" of the Antoinette. It does require more effort in construction than the usual r.o.g. because of its angle-cut joints, but of-fers more visual interest in exchange.

The plastic propeller and its bearing are from a North Pacific 'Skeeter' ready-to-fly model and may be used 'as is'. However, by replacing the propeller shaft and adding some brass or teflon thrust washers, efficiency may be improved. Materials required include: Several 1/20 square balsa strips, 1/4 x 1/8 balsa strip, lightweight covering tissue, .025 diameter music wire, and 3/4 inch diameter plastic wheels. (Note: 1/20 in square strips are commonly used for Peanut Scale models, but may not be found at some hobby shops. In such a case they may be ordered by mail from Peck-Polymers, PO Box 2498, La Mesa, California 92041 or Mike Mulligan's Old Timer Models, P.O. Box 913, Westminster, Califor-nia 92683.) Firm lightweight 1/16 square balsa strips may be employed instead if desired.

Suggested tools include: single-edge razor blade, modeling knife with pointed blade, sandpaper block or stick and straight pins. Building may be done on a flat, soft surface such as insulation board into which pins may be easily pushed.

Construction: Although you could build directly over the full-size plans, why not buy a photocopy of the page and preserve your Flying Models magazine? Remember, it may be a collector's item some day! Cover the plan with trans-parent kitchen wrap to prevent glue from adhering to it.

Wings: Construct the wing panels from firm straight balsa strips joined with your fa-vorite glue. Cut the longest strips first to minimise waste. Try for concise, workman-like joints which not only appear better but contribute greater strength. Secure all strips in position while drying with common straight pins 'Xed' over the strips rather than piercing them which could cause weak spots. Allow glued joints to dry thoroughly before removing panels from the building board..."

Notes

* 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.

Scaling

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.
