Quote: "Build a Flying Model Beechcraft. How You Can Build a Model of a Unique Commercial Plane That Will Give Fine Performances

THE model given here is a scale model of the Beechcraft, a new biplane having negative staggered wings. The large ship is exceptionally well streamlined and the model faithfully duplicates this feature. The model is a fast flier and very rugged, the test model making over fifty flights before a weak I-strut broke. Five or six flights later, a hard landing fractured a wing spar.

The order of construction as given here, while unconventional, has been carefully worked out to allow use of the plans to the greatest advantage. Do not cut out any patterns unless the written instructions so indicate; all others should be traced on thin paper and pasted to light cardboard, then cut out for patterns. If all instructions are followed, there will be no part of the drawings cut up that will be needed in future construction of the model.

This ship when at rest has a very large groundangle which helps, from a standing ROG start, to get the model off the ground within four feet (with only 100 winds in the motor).

Wing (Plate No.1): Construction should begin with the wings, due to the fact that the bulkheads for the fuselage, printed on the reverse side of the page, must be cut out after the wings are built.

Begin the top wing by tracing right half from the left half given and joining at the center line. Now trace rib pattern No.1 and cut fifteen from 1/32 balsa and two from 1/16 balsa, Next trace rib patterns No.2 and No.3. (Do not cut rib patterns from drawings as this will spoil bulkhead patterns). Cut four of each of these ribs from 1/16 stock, two of each of these are to be used for the bottom wing.

Place the whole wing layout on a smooth board with waxed paper over it to prevent the finished wing from sticking, Pin leading and trailing edges in place and :glue in ribs, leaving the center rib out. (Note position of the two No.1 1/16 thick ribs).

Cut, tracing patterns first, the wing tips from 1/8 stock. These are fastened in place with a 7/32 block under the tip and with the top of wing tip piece even with the top of the leading edge, Glue rib No.2 in place with a 3/32 block underneath and No.3 ribs with a 5/32 block. The top of the wings should be level, all taper of the tips being on the bottom of the wings. A ruler laid across the ribs at their highest point should touch all ribs and the outer point of the tips..."
