About this Plan

Flakey. All-sheet rubber sport model.

Quote: "Sheet-balsa construction and all straight lines make this rubber-powered model a cinch to build. Flakey, by Jean F Andrews.

Meet Flakey, an easy-to-build rubber-powered model which will fly circles around the park all day. The orginal has more than fifty flights without crashes, and averages from 45 to 50 seconds duration a flight.

It has been flown without difficulty by the author's children, ages six and eight. Construction is the easiest we've seen yet on a cabin model. Bending of a landing gear and carving a prop, points of construction which give the most difficulty to the advanced modeler, as well as the beginner, are eliminated by using the gear and prop from North Pacific Products ready-to-fly models.

If you want to get started in this fascinating hobby of free-flight models by making Flakey, assemble the following items before beginning construction:

MATERIALS LIST
1 x North Pacific Products propeller from a Star Flyer or Sleek Streek (either one will work. We used the Star Flyer on the original.)
1 x Nose plug for rubber model. The photos show the gray plastic Williams Brothers plug, but any type can be used if the noseblock Is cut to fit it.
2 x Sheets of balsa. 1/16 x 3 x 36 in. We used 4 inch wide stock, and had plenty left over.
1 x Rubber-model thrust-bearing washer. There are is lot of these on the market, both by mall order and at the local hobby shop. If you can't find one a couple of small brass washers or glass beads will work.
1 x Packet of 1/8 rubber. Sig sells this in packages of about 25 feet, We will only use four feet of it for the motor in the model, but it pays to have a couple of extra tubber rooters for replacement.
1 x Bottle Of some type of rubber lube, to lubricate the motors. Sig also markets this. Straight tincture of green soap, sold at drugstores, can also be used, as can plain margarine, melted In the palm of the hand.
1 x Tube of model cement. Make sure it's the type for wood, rather than the glue for plastic models. A small tube of Contact type cement, usually labelled 'Instant Dry' or something like that, will be handy in making the wing, although it isn't essential.
1 x length of .075 in diameter music wire, for new propeller shaft.

Construction: The wing probably is the most difficult part to make, so let's start there. Lay a piece of your sheet balsa under the plan and outline the wing rib by repeatedly pushing a pin through the plan and into the wood. Carefully cut out this rib, and use it as is template for all other ribs; lay it on the wood and carefully draw the outline around it with a soft lead pencil. Twelve ribs are required.

Lay out the two wing halves using the pin-through the plans routine as above, noting that the inside or center edge of the wing blank Is slightly concave (curves in). This is done to the two wing panels can be joined later at the center at the proper dihedral angle. Mark the location of the ribs on the underside of the blanks, making sure the second rib from the inside is exactly one-half inch from the first slanted rib on the curved inside edge. This second rib will match up..."

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.
