All American (oz14148)

About this Plan

All American. Control line speed model.

Quote: "Win With the All American. By Bob Lauderdale.

YOU'LL HAVE a good chance of breaking the world's speed record with a copy of the 'All American.' For even though this lightning-like model plane holds the present world's record of 172 mph for propeller-driven models in FAI (Federation Aeronautique Internationale) competition, it has been timed unofficially at speeds as high as 180 mph. Entered in the 1957 National Model Airplane Championships in Philadelphia, the All American broke the world's record of 158.26 mph held by Laszlo Berke of Hungary, and later, daring the 1958 Nationals at the Glenview Naval Air Station, set a sizzling speed record of 172 mph, for which the author was awarded a certificate from the FAI.

Those who build and fly this speed model will find it very stable and easy to fly, and since the only differences between the FAI design and the conventional speed model are the weight and the greater supporting area, the All American can be flown in regular AMA (Academy of Model Aeronautics) Class C competition.

The original All American used a Magna magnesium pan, a Stanzel Class B control unit and a McCoy 60 Redhead racing engine. These, or similar parts, plus basswood, balsa, cement, wood putty, etc, will have to be purchased beforehand from hobby shops.

Start by smoothing the outside of the magnesium pan with a file and then sand and polish it with line rubbing compound, such as DuPont No 7. After the pan has been completely finished on the outside, locate the holes for the engine-mounting screws. Be sure in locating these holes that you allow for a small amount of left thrust adjustment, about 2 deg. Make the holes 1/4 or 5/16 in deep with a No.33 drill and then tap them with a No.6-32 tap.

The crutch is made next. Select a piece of straight-grained basswood or pine, 7/8 x 2-1/2 x 16 in and using the nagnesium pan as a pattern, trace the outline of ther pan onto the crutch blank as in Fig.1, and saw it out..."
