About this Plan

Damsel Fly. 27 inch wingspan flying boat for up to .4 cc engines, by Vic Smeed.

Quote: "A delightful little flying boat for small diesels or glow motors, from the drawing board of Vic Smeed.

This little model originated in a conversation with Mike Parker (the Hull one, who writes alternating columns in 'Sam Speaks') who had built a Sea Nymph (oz1807) scaled down to 24 in and christened it 'Nymphette'. Powered with a Derek Giles Mills 0.13 cc, it flew around very sweetly, intrguing Mike to the point of wanting to build another little flying boat - if possible one with the wing on top of the hull, rather than on a pylon above it. Had I ever designed one like that?

Well, as it happened, there had been a couple of smallish ones like that around 1948/49, one of which is shown in a photograph. This was 37-1/2 in span, Mills 75 powered, and looked a bit on the flat side; I remember that the dihedralled tailplane was intended to prevent it submerging in the wash on take-off. The second one was about 40 in span with a K 1 cc motor and not quite so squashed-looking; there exists a photograph which will probably turn up just after this article is published - I cannot for the life of me remember what happened to either of these models, but almost certainly they would have been sold (for peannuts) once they'd been test-flown.

The design emerges. The outcome of the conversation was the Damsel Fly, which was kept very simple to address one point in the discussion which hadn't been finalised - what size motor was it for? Mike has a wide collection of small IC engines and had pointed out that it would always be possible to have a drawing enlarged or reduced to suit a chosen motor - its so easy with modern print shops. To change the span to say, 30 in or 24 in would be easy enough and would need no alteration to material sizes or weights; there would be a fractional Change in CG position, within the bounds of normal trimming..."

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.
