About this Plan
Eaglet. Embryo rubber model. Wingspan 18 in, wing area 49 sq in.
Planfile includes full build instructions.
Quote: "This little airplane is designed for high performance. Evidence of this is its record of four first places in the Embryo Endurance event. To be eligible the model must have less than 50 sq in of wing area, have a fuselage section 1-1/4 x 1-1/2 x 3, and take off from a card table. A bonus of five points is added for a cabin or cockpit. Maximum flight time recorded is two minutes for each of three flights.
The result is a miniature endurance model for developing competition skills, and a great fun model for small fields. For, even though soaring flights are easily made, winding the motor to a lesser amount provides countless gentle, rise off ground circling flights in small areas like school yards or neighborhood fields on those quiet windless evenings.
Study the plan before beginning instruction to become ac-quainted with various details. Carefully remove die cut parts from the 1/16 sheet balsa, using a sharp pointed model knife to free the parts if necessary.
FUSELAGE ASSEMBLY: Cover the side view of the fuselage with transparent plastic wrap to prevent cement from adhering to the plan. Assemble both sides at the same time, one on top of the other. Locate the longerons on the plan between pins. Fit two of each crosspiece and cement between longerons. When fully dry remove from plan and separate sides by carefully slipping a thin razor blade between the longerons. Join the sides with formers F-3, positioning assembly inverted on top view of fuse-lage. Bevel and join longerons at tail, join at nose with die cut reinforcements F-4. Fit crosspieces of 1/16 x 3/32 strip. Refer to Fuselage Assembly sketch.
Position formed wire landing gear legs on plan at 'View at F-3'. Cement doubler F-6 to wire. When dry install assembly in fuselage against F-3 and reinforce gussets F-7. Add under fin F-5 to rear of fuselage and fit scrap 3/32 sq stabilizer supports to upper end. Cement fin locating wedges F-8 into top of fuselage.
WING AND TAIL ASSEMBLY: Erect tabs in Jetcomatic assembly jig and tape to a flat soft wood or wallboard scrap. Set three ribs in slotted positioning tabs and cement to 3/32 sq leading edge pushed against leading edge tabs. Cement trailing edge to rear of ribs. Install remaining ribs and 1/16 x 3/32 spars in notches in tips of ribs. Be sure to allow spars to project beyond the left end rib on one panel and beyond the right end rib on the other panel, in order that the spars can be tied together at the center by gussets W-2 and W-3. When dry remove wing from jig and add bottom spar. Refer to Wing Assembly sketch..."

* 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.
