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..."
Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
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.
