This is what is called a 'profile' model in that the fuselage is a single sheet of wood. For a trainer it is a very simple and strong method of construction. You will need one 36 in sheet of 1/4 x 4 in medium balsa, a piece of 1/8 sheet, a piece of 1/16 ply, a length 14 and one of 18 swg wire for the basic construction.
First cut off 19 inches of the1/4 in sheet, mark the centre line (9-1/2 in) of this piece and mark a point 2 inches in from one edge at each tip. Join these points with the centre line and cut off the two shallow triangles resulting. Cement these pieces to the straight edge on the other side, wide ends touching at the centre line. Finish drawing the wing shape, 3 in wide at each tip and 4-1/2 in at the centre, and cut off the surplus. The wing must now be thoroughly sanded to the section shown. Use a sheet of glasspaper folded round a 6 x 4 in block; trace and cut the top curve out of a postcard and hold it to the top of the wing from time to time. The section is not critical, but should be reasonably close to that drawn.
Draw the fuselage on the remaining 17 inch piece of 1/4 in sheet; it will not be quite long enough, but the nose end has a 1/16 ply plate each side, so that it will be quite strong enough if we make it up to length a little later. Cut out the fuselage, and mark and cut the two ply plates. The size of the cut-out in the centre will depend on your engine, so measure the width of the crankcase and how deep you will need to cut out the slot, then mark and cut out. A fretsaw is useful for this, but if not available saw the two horizontal cuts and use a knife for the third side. Cement one plate to the fuselage, fill in the nose with 1/4 in sheet, cement on the other plate and leave under a weight to dry thoroughly. The extra 1/4 in sheet can be trimmed off when dry.
Check that the wing fits nicely to its seating on the underside of the fuselage and that the 1/8 in slot for the tailplane is a good fit. Sand the fuselage, rounding the top and bottom corners (except at the wing seat) and mark the undercarriage positions. Drill holes for binding the wire in place, and also for the engine mounting bolts.
Cut out the fin, tailplane, and elevator, and hinge the elevator to the tailplane with narrow tape, as previously described, after sanding carefully. Cement the tailplane firmly into its slot, lay the wing on a flat surface, and cement the fuselage to it. One coat of cement allowed to dry before bringing the pieces together, then a second coat on making the join, gives a very much stronger joint. Make sure that wing and tail are parallel and square to the fuselage. The fin can also be cemented on at this stage; position it so that the trailing edge lines up with the right hand side of the fuselage and the leading edge with the left hand side, so that it is slightly angled to turn the model to the right.
While this assembly is drying, bend the undercarriage to shape. The main wheels require a 14 in length of 14 swg wire. First bend it into a long narrow U, 1/4 in wide (inside) at the top, then 2-1/2 in down from the top bend each side out to the angle shown. Bend the remainder to form an axle each side. The nosewheel is a single leg..."

User commentsHello, hope you're all well during these strange times ...photo of a rare Vic Smeed control line design [main pic]. Found in one of his books in where else, the book section of this superb site. Keep well. Best regards,

* 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.
