About this Plan
Frog Firefly. Free flight sports biplane power model.
Quote: "The fuselage was two moulded half-shells, with brown paper on the inside of the balsa. Would have to decide between moulding over a former, or plotting some bulkheads and planking. It lends itself to a colour scheme from the US navy of the 1930s. I haven't decided on the mods to cope with the lack of kit parts yet."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

Nice work - I always thought I'd like to build this myself, but was never sure how to make the fuselage.

Fuselage is similar to Frog 'Fox' in that it was originally 2 half shells. I got round this by making octagonal formers, and using 3/16th softish balsa to make the vertical sides, and the top and bottom. This was then sanded flush with the formers before adding the diagonals of 1/8th balsa. It was then 'just' a sanding job to get everything nice and round. I covered mine in tissue. It looks like a baseball bat, is just as strong but a whole lot lighter. It was great fun and I haven't broken it yet. Hope this helps.

Managed to pick one of these kits up yesterday, seems complete with assembly plan?

* 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.
