Before starting construction of your model, study the plan and construction procedure carefully so that you will have a complete understanding of the step-by-step method of building this airplane. Guillow engineering has provided you with the most up-to-date method for building a real scale flying model. Only careful attention to detail will insure the success of your efforts. Most prize wining models are the results of patience and careful workmanship. You too, can achieve success by following
the example of champion model builders — by working slowly and carefully at all times. The frame photographs shown on this instruction sheet are actual pictures of the model you are about to build. The line drawings under each photo show the method of frame construction but are not the actual illustrations of the model you are making. In other words, refer to the line drawings for construction procedure — refer to the photos for con­struction details of your model.
1.   Pin top and bottom keel parts "A" over fuselage layout.
2.   Cement one each of formers "B" into position on keel — be sure formers are at right angles to keel.   
3.   Cement side keel "A" into deep notches of formers "B".
4.   When dry, remove frame from plan. Cement other halves of formers "B" to center keel; then add remaining side keel. Add former "B-B" if shown.
5.   Cement 1/16" sq. stringers into their respective notches. NOTE: To obtain uniform tension on fuselage, cement stringers alternately to left and right sides and top and bottom. NOTE: On some models, certain stringers are not cemented in place until parts "H" and "J" are first cemented into position.
     These particular stringers will be noted as such on the side view of model
6.   If part "H" requires 1/16" sq. uprights, pin part "H" to plan and cement uprights into position. When part "H" is dry, remove from plan, crack at position shown if noted and cement to fuselage
7.   Cement gear parts "J" into long slots in formers "B2" and "B3". Cement remaining stringers into place.
8.   Cement parts "L" into place and also any 1/16" sq. cross pieces as shown. NOTE: Some 1/16" sq. braces are cemented in place after the fuselage is covered — these are noted on plan.
9.   Lightly sand fuselage to remove balsa fuzz and excess cement.
BUILDING THE WING FRAME
1.   Pin to plan, and cement respectively to each other, all "E" parts of left wing.
2.   Cement leading edge and spar in position.
3.   Cement wing ribs "F" into position between leading and trailing edges and to spar.
4.   Cement the top 1/16" sq. spars into rib slots. Cement 1/16" sq. stock to tips as shown
5.   Follow the same procedure in assembling the right wing half.
6.   When dry remove wing frames from drawing plan. Sandpaper the leading edges to shape and gently round all other edges.
Common Aircraft Terms
BUILDING THE FUSELAGE FRAME
COVERING THE FRAMES
BUILDING TAIL SURFACE AND OTHER FRAMES
When attaching tissue covering to frames, it is best to use thinned out clear dope as an adhesive instead of cement, or full strength dope. Mix thinner and dope about 50-50 for proper consistency.  Only apply dope to OUTSIDE edges of areas being covered—do not apply dope to frame work within area covered by section of tissue.
FUSELAGE: First cover any flat surfaces such as sides and bottom of frame. Cover curved areas of fuselage in sepa­rate sections — vertically between formers. Dry fit tissue over curved sections to see how much of an area can be covered with one piece of tissue without wrinkling. Cut tissue slightly larger than area to be covered then trim off excess after attaching to frame.
WINGS: Cover bottom of wings with single pieces of tissue.   Cover top of wings between root rib and tip rib with one piece of
tissue. Cover center sections and tips with separate pieces of tissue.
TAIL SURFACES: Cover both sides of rudder and top and bottom of stabilizer with single pieces of tissue.
DOPING THE COVERED PARTS: After covering is completed and all excess tissue is trimmed off, spray tissue with water from an atomizer and let dry until covering becomes smooth and taut. For best flying performance, the model should be kept light and it is suggested that only one coat of clear dope be applied to the surfaces. (If model is to be used for display only, it can be given several coats of clear dope then finished up with colored dope.) Lightly sandpaper remaining balsa parts and apply one coat of dope to all surfaces.
1.   Pin to plan, and cement respectively to each other, all   rudder parts "C". Cut 1/16" x 3/32" members to size and   cement in position.
2.   Build stabilizer frame in a similar manner using parts 1/16" x 3/32" members.
3.   Remove frames from plan and sandpaper lightly,                round­ing all edges.
4.   For models with V wing struts, assemble parts K over plan.
ADJUSTING AND FLYING THE MODEL [rubber powered]
COMPLETING THE MODEL
ASSEMBLING THE MODEL
To extend the flight duration of your model, the use of rubber lube is recommended. Up lb 50% more turns can be wound into the rubber motor by its proper use. For warm weather, use a mixture of two, parts GLYCERIN and one part GREEN SOAP, For flying in colder weather, use one part glycerin to one part green soap. (Glycerin and green soap available at your local drug store.) Place a few drops of this mixture in your hands and rub into the rubber motor. Stretch rubber motor a few times and wipe off excess rubber lube. Wind the rubber slowly the first few times to force lube into rubber. DO NOT use rubber lube on a rubber motor unless the model has been clear doped. Non-doped tissue will absorb the lube and make it sag.  Ready mixed rubber lube is available in some hobby shops in 2 oz. bottles.
1.   Full scale details of a non-flying scale propeller are shown on plan. No material is furnished in the kit for this part but it can be made from other balsa or you can re-work a small gas motor propeller obtainable at your local hobby shop.  Use this prop only for exhibition model.
2. Finally add the decals as per instructions on reverse side of decal.
1.   Check wings for possible warps. If warped, correct by holding the warped section over steam from a boiling kettle and twisting gently in the opposite direction until wing is straightened — be careful and don't get scalded!
2.   Test glide model over grassy area by gently thrusting model forward from shoulder height. Adjust model for level flight by gently bending stabilizer either up or down to compensate for a dive or climbing stall, ("up" stabilizer for dive — "down"
stabilizer for stall). If model veers right or left, adjust for straight glide by bending rudder in opposite direction of curved flight.
3. Wind propeller 100 turns (clockwise when facing nose of model) and gently thrust into prevailing wind. If model climbs too rapidly or goes into a stall, correct flight by bending rudder slightly to the right to give a climbing right turn. Longer flights can be made after initial tests by winding propeller motor up to 200 turns
1.   With a sharp razor, remove tissue from around notches in wing ribs that receive the wing struts.
2.   Carefully cement windshield to fuselage. Pin in place till cement dries if necessary.
3.   Cement left wing to fuselage and pin to hold location. Cement strut into notches in wing and t fuselage as shown.
4.   Repeat this procedure on right wing
5.   Cement stabilizer to fuselage. Line up carefully. Cement rudder to fuselage also. Cement tail wheel "K" to fuselage
6.   Whit needle nose pliers, form the landing gear wire parts to fit the drawing and cement to fuselage and strut
7.   Slip wheels on axles and either bend up ends of axles with needle nose plier or put a bead of cement on end of each axle.
8.   At this time, balance the model at the point shown on the plan by placing modeling clay to inside and bottom of fuselage directly behind former "B1". Press the clay firmly in place so it will not dislodge.
9.   Trim nose cowl to shape and slip over nose of fuselage. Bead all around the edges with cement.
10.Assemble propeller, prop hook, bead and nose bearing as shown on plan. Install rubber motor as follows: Insert one end in fuselage and fasten in place by sliding rear mount (cut from excess axle wire or use round toothpick) through loop and "L" parts. Attach other end of rubber loop over prop hook and slip propeller unit into hole in plastic nose cowl.
