About this Plan

Jitter Bug. Free flight gas model. Reprinted in SAM Speaks.

Quote: "Most of you model fans are desirios of building a contest model that will climb to a very great height for a given amount of motor run depending on contest rules. You will thrill at the steep spiral climb which this model will maneuver. At the top of the climb it will flatten out and glide for a long time, depending on air conditions. This model with its beautifully streamlined fuselage, painted in bright red and with its silver nose, makes a very striking appearance wherever flown.

By increasing the plans four times the size shown in magazine, the correct size will be had for the construction of your model. A larger model may be built by increasing the plans as many times as you so desire. Our model of this particular design has flown so remarkably well that we advise you to build it the same size as ours, which is four times that shown in magazine.

Construction of Fuselage. Secure some 1/4-inch square hard balsa strips for the building of the rectangular shaped inner fuselage. After making sure this part of fuselage is absolutely true, the formers are next attached. These are cut from 1/16-inch balsa. The 1/16 x 1/8 inch hard balsa stringers are next attached. Positions of these are shown through the various sections of fuselage shown on plan. You will note on the plan, small sections of the formers are citt out between stringers as indicated by dotted lines, so as to give a neater covering job. A great deal of construction is required around the cabin which is composed chiefly of 1/8 inch square balsa to support the strain from the wing.

Construction of Landing Gear. This is formed from 1/16 O.D. piano wire being securely tied into fuselage with strong thread and cement. Struts may be faired in with 1/8-inch sheet balsa so as to add to the appearance. Stream-line wheel coverings may be added if so desired but are not necessary. These are used chiefly for display purposes.

Construction of Elevator and Rudder: The elevator is built upon a flat surface from 3/16 inches square and sheet balsa. There are two sections to this elevator, one left and one right, and they arc cemented well up on the rudder support by two struts on each side of bottom side of elevator. The elevator is not cemented to rudder until it has first been covered. If you will notice closely, the rudder is very neatly faired into rear of fuselage, this being done mostly by the method of attaching the bamboo paper between the rudder and fuselage. When shrunk with water it forms a perfect fillet on either side of rudder..."
