About this Plan

Swallow. Lightweight flying-wing glider, from Aeromodeller July 1947.

Quote: "A 60 inch span Lightweight flying-wing glider. Swallow, by GD Miles.

MODELLING tyros anxious to make their first attempt at a flying wing design will find the Swallow 'just their cup of tea', with the additional attraction of a model that soars like a bird and no complicated trimming procedure to worry them. Seven minutes thirty-seven seconds from a three hundred foot line and a further time yet to be ratified as a British record should more than satisfy any doubts regarding performance, so here are the building instructions as specified by the designer.

Building Instructions. The ribs are first cut out of 1/16 in medium balsa, and slotted for spars. The tip rib is thinned down so that the top spars, lie level. The wing is then constructed in the usual way, making sure the ribs are set right. The trailing edge packed up with balsa to suit rib shape.

Whilst the wing is setting, the elevon is built inside it. The dihedral brace is steamed to the requisite angle and glued to the spars with Casco cold water glue. The brace also acts as the back of the weight box.

The washout is steamed in whilst the wing is pinned to a board. Insert 1 in blocks under the tips at the trailing edge. The model is then covered in tissue and given two coats of dope. Slots are cut for the-tabs, and the elevon is fitted.

Trimming. My own model flies with one tab level and the other up 1/16 in for turn. The model should be weighted until a flat glide is obtained. Weight should be evenly distributed in each box. If the model is required to turn, the elevon inside the turn should be up. The model, once trimmed, is very stable and is recommended for the beginner.

Full-size drawings (see quarter-scale reproduction opposite) are available from the Aeromodeller Plans Service Ltd."

Nice little light glider. Might make for a fun evening flight RC glider with micro hi start. Will have to do some calculations as there is no CG noted on plans or supplement.

Added some nice pics of the finished model, thanks to Doug Forbes [more pics 003-005].

Notes

* 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.

Scaling

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.
