About this Plan
Stringbagette. Free flight sport model loosely based on the Fairey Swordfish ('Stringbag') WWII biplane torpedo bomber.
Quote: "This evocative design based on the Fairey Swordfish is guaranteed to go down well with any scale enthusiast. Stringbagette, by Peter Antram.
This free flight model is intended to give an impression of the Fairey Swordfish combined with the practicality of a sports biplane, hence the name; a sort of small stringbag!
Any model flown at our local meadow has to be tough as the trees keep leaping out to catch them, not to mention the shepherd's feeders and the farmer's trailers (I said not to mention the feeders or the trailers!). For the same reason, the wing and undercarriage strut arrangements are greatly simplified or left off altogether (what could be simpler or lighter?).
As there is a lot of wood used, choose light but tough timber and 'Bagette' will bounce well.
Construction: I like to start with a ldt of parts already cut out and bent up so that the plan can be secured and film protected without need to disturb it for carbon copies etc.
The tail feathers are a simple all-sheet job - important not to be too heavy though.
The wings are of similar construction but far from the same shape; for some reason Faireys seemed to give each component to a separate design group who were not on speaking terms with each other!
The large amounts of 1/16 sheeting make for strong wings and the thick sections of balsa at tips and centre-section allow for the carving of these complicated shapes. The flat vertical trailing edges at the centre section were to accommodate wing folding on the Swordfish and helps with the impression.
Choose light, tough timber carefully and cut out a kit of parts - it helps no end to be able to pick up a part as you need it instead of having to rush back to the plan and cut another bit before the last lot of glue dries!
I built each wing panel flat then joined them using the dihedral braces, completing the centre sections when set. The top wing joiner is cut from sheet and sanded to the taper shown, using clothes pegs to hold while the slow-set glue dries. The lower wing uses a flat joiner, note that the rear spar needs sanding to a taper to fit under the rear joiner.
I suggest the fuselage construction is started by drilling the 3/8 x 3/8 spruce engine bearers to suit your motor (the plan shows an Indian Mills 0.75) then fitting the bearers..."

* 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.
