About this Plan

Blackfly Mk1 A/2. Free flight competition glider. Quote from the designer: "Blackfly F1A (A/2). This model was designed in mid 1971 while living in a mining exploration bush camp in the West Pilbara area of Western Australia. Anne (my ex-wife) and I built one each and competed in the Australian Nationals in Northham WA in 1971. I later lost mine, and Anne flew hers in the 1972 Nats in Geelong in 1972. The other photo shows me launching Anne’s model at that contest. On returning to Ireland in 1974, Anne won both FAI glider and Open glider with her well-worn model (photo). I built two more but both were lost to Hung. Probably the most consistent flying A/2 design I have had. A bit outdated by today’s standard, but that model liked thermals. The Mk 2 had an increased tapered wingspan of 80in." This is a modern redrawn plan in PDFvector format.

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.
