PZL-1 (oz9886)

About this Plan

PZL-1 Polish Fighter. Rubber scale model.

Quote: "Build Your Own Polish Fighter. Make a Flying Model of This Zippy Craft at Small Cost and Little Trouble. Here's How!

THIS month we shall construct a very unusual model, the PZL-1. This Polish pursuit ship is one of the outstanding European fighters. Its construction and design are in line with the growing tendency, especially on the Continent, towards monoplanes for pursuit purposes. The United States has not done so much in this line in pursuit ships, but will probably do so in the near future, as several monoplane types have been accepted, such as the Curtiss AB Attack and the new Boeing Bomber.

The PZL-1 is a product of the Panstwowe Zaklady Lotnicze of Warsaw, from which it gets its name. Great interest was shown at the 1931 Cleveland Air Races in the PZL-6 ship which Captain Orlinski, of the international acrobatics team, flew. This is a version of the PZL-1, but with an air-cooled motor. The latter was chosen as a model subject because it is a bit more unusual in this country. Its span is about 35 feet. Both ships are of all metal construction throughout, including all coverings, corrugated dural being used on the wing and tail surfaces and smooth dural on the fuselage.

The performance of the PZL-1 is a little better than that of the PZL-6 because of higher power and less head resistance. The motor is a 600 HP Hispano Suiza, giving a high speed of 191 mph, with a climb of 16,400 feet in 8 minutes. The engine is cooled by a retractable Lamblin radiator. This is not shown on the model as it would cut down the performance and add weight. It may be added if desired, however, and goes just in front of the landing gear.

The foregoing history of the PZL-1 is short but will serve to acquaint the reader with the type of ship that is to be constructed. The builder will do well to keep in mind the necessity of reading over this article thoroughly at least once, and to study the drawings so that no mistakes will be made when construction is finally started.

Fuselage The sides of the fuselage are made first as usual. The longerons, uprights and diagonals are all of 1/16in square balsa. After one side is laid out on the board and the glue is dry, outline along both sides of all pieces with a soft pencil. Then cut it off the board and lay out the other side. Since this fuselage does not have a flat bottom, a little different procedure is followed to assemble it. Therefore, when the glue is dry on the second side, do not remove it from the board. Instead, glue in place the formers..."
