About this Plan

Deluxe. Free flight gas sports model.

Quote: "THIS model is the author's 'dream job' of a full sized plane. From past experience with rubber powered models, and with knowledge gained studying aircraft design, it was decided to combine realism with practical construction. In an earlier issue of Model Airplane News my idea of contest rules was outlined in the 'Airways' column. With these rules in mind the plane was built to garner a maximum in:

(1) Design Points (possible 33-1/3%)
(2) Construction Points (possible 33-1/3%)
(3) Flight Performance (possible 33-1/3%)

The plane climbs in a right circle and pulls out smoothly due to its fine aerodynamic setup. Glide is in large right circles.

Fuselage. First enlarge the plans to full size. The side view and top view of fuselage with rudder and tail shown are all that are necessary at first. In the conventional method lay out the sides using 1/4 in square hard balsa (or pine) for longerons, crosspieces and diagonals. Glue gussets of 1/16 mahogany plywood to all joints on the inner side as shown.

Since the upper longeron is a straight line, the sides can be turned upside down and the workbench used as a jig while placing in crosspieces. Cut crosspieces at Stations 14-11/16 and 21-5/8. These station designations also represent the distance back from the nose of the ship (marked 0). The crossections are about equal at these two points and the sides should be propped up vertically.

To keep the fuselage rectangular, it is advisable to temporarily tack crosspieces at Sta. 14-11/16 on lower longeron and at 21-5/8 on upper longeron. Pull the front end together and place crosspieces to fit Sta. 4-5/8. After glue is dry at front, the upper longerons should be tapered, so that the total width at end is 3/16 in. The lower longerons need not be tapered as they are cut off at their intersection. Pull the longerons together and glue.

Using 1/4 in square stock, cut crosspieces to fit and later the diagonals. Both upper and lower diagonals run in the same direction. Next glue on the floor and upper motor mount gusset. View A shows in detail how to install the motor mount clips..."
