BUILDING INSTRUCTIONS: INTRODUCTION: This Model is intended for the beginner, and so long as the following instructions are followed stage by stage, and studied carefully in conjunction with the plan before starting construction no difficulties should be encountered.
Performance, as with any model aeroplane, is relative to the ability of the builder; the better the workmanship, the better the performance. And, finally, a word of advice, don't rush the job. Correcting errors through hurrying will take just as much time as working steadily. Don't set yourself a time limit; if you do manage to finish the job in record time in order to 'fly it tomorrow,' you will probably be disappointed by adverse weather conditions. Take your time, and have a model that you can be proud of.
PREPARATION AND EXTRAS: You will need a smooth, true board or table (one that you may knock pins into). A balsa knife or steel-backed razor blade. A dozen or so ordinary pins. Fine sandpaper. A small straight-edge, and, finally, a soft half-inch brush. There are three things, not supplied in the kit, that you will need for the completion of your model. A small tube of tissue paste for sticking the tissue covering to the wing frame, a one-ounce tin of clear shrinking dope, and finally, four feet of 1/8 inch flat Dunlop rubber. These are all obtainable at your model dealers.
CONSTRUCTION: Where the term 'cement' is used in reference to joints, in every case BOTH surfaces to be joined should be coated with cement.
Cut from printed balsa, side panels P and S, and formers A to F. Cement formers C and D between side panels, using dotted angles. While this assembly is sticking, make certain that sides are in line, and that the formers are "square" with the sides. Now carefully bend sides inward at point E (slight scoring on the INSIDE at this point will help to give a sharp bend).
Next, cement formers E, F, B, and A in position, in that order. (Where sides are bent inward at the nose, a rubber band around the nose will hold sides to former A while cement is setting). The tail-post from 1/8 x 1/8 balsa can now be cemented in place at point G.
Now cut two side-window frames from the 1/32 balsa supplied, using the template given at the bottom left-hand corner of the plan. Carefully cement these in place across formers C and D. Cut wing supporting pieces from 1/8 x 1/8 balsa to fit along inside the top of the window frames between formers C and D. (Slight chamfering of the outside edge of these supporting pieces will give a good fit against the side-window frames, and leave the tops level for the wing to rest upon).
Bend undercarriage, to pattern given on the plan, from steel wire supplied. Smear corners between former B and sides with a liberal coat of cement, and fit undercarriage in place according to dotted lines upon former B. Pins may be used to retain this in place while the cement is setting. When set, apply a further coating of cement to wire-corners, so that a small fillet of cement is formed over the wire.
Cut nose covering from 1/32 balsa, to pattern given on the plan. Also top rear, and bottom from 1/32 balsa, to top-view fuselage outline. These can then be fitted, and finally cemented in place as shown on the plan. The nose-block is then drilled and cut to shape as shown on the plan. A small hole can first be made with any sharp pointed tool or metal skewer; and then reamed out with sandpaper wrapped around 1/8 dowel..."

Quote: "Hi Mary, Here's a different Jasco Spotter plan (oz7194) with instructions, printwood and photo."
Note see Jasco Spotter (oz7194) for a CAD-redrawn version of this plan.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsThis plan seems to be the original version of the CAD drawn plan Jasco Spotter (oz7194). Perhaps it would be worthwhile linking the plans to one another via hot links in the text?

Agreed. Got it. Done now.

* 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.
