Quote: "A Corben Super-Ace Model, by Paul Lindberg, model editor and model designer for Popular Aviation.

We are sure most of you fans are familiar with this popular sport model, which is powered with a Model A Ford motor.

The model is an extremely good flyer, having unusual stability, plus speed and duration. This model, like all other models developed by our laboratory, carries all possible details in accordance with the real ship. All movable controls with aluminum hinges, a real shock-absorbing landing-gear, radiator with screening, exhaust pipes, and scale propeller go into the making of this trim model.

COLOR SCHEME: Wings and tail surfaces, yellow. Fuselage, black and yellow. Struts, black. Spinner, red.

CONSTRUCTION OF FUSELAGE: First, place wax paper on top of plan, to prevent parts from sticking to plan. The fuselage sides are built from 1/16 square balsa. The longerons, verticals, diagonal braces, etc., are held in place until securely cemented by inserting straight pins on either side of strips wherever needed.

When the two sides are completed, the cross-members are cemented into their proper locations. Check carefully front to rear for alignment. Cut the formers from 1/32 sheet balsa and cement in their respective positions as shown on plan.

The positions of all stringers are shown on the formers, there are very few stringers on this model, as the sides of the fuselage are flat. Three short stringers are placed between Former 6 and the bottom cross-member of fuselage.

Take great care in making all balsa nose blocks. The front part of fuselage back to cockpit is covered with several pieces of stiff paper, see plan. The louvers in side cowls may be made to stand out by cutting a slit in the back edge and gradually work an opening to confirm with that shown on the plan.

LANDING-GEAR: This is made in very much the same manner as the landing-gear on the large ship. The details are very clearly shown on the plan, and no trouble should be encountered here. It is very necessary that you splice in a piece of 1/16 dowel in front wing strut to receive load from shock strut.

CONSTRUCTION OF THE WING: Cut all ribs from 1/32 balsa. Pin center spar in position on the plan. Now, cement ribs in their proper locations. The leading and trailing edges are cut and sanded to shape and cemented to the ribs. The wing panels carry movable ailerons which are a great help in controlling the flights. Make wing tips from 1/16 thick balsa. We highly approve of this type of wing tip, because it is much easier to construct and neater in appearance..."
