Leprechaun 2 (oz8397)
About this Plan
Leprechaun. Towline glider model. A 67in vintage free flight glider model.
Quote: "50 years on - 67 inch span version of Dick Twomey's classic glider design.
When AeroModeller published the plans for the mighty 103in span Leprechaun (oz3252) in March 1950, they began the birth of a legend: for the next couple of decades its sheer size was inspirational to many, and it was indeed a dream to fly. Nothing else, it seemed, came close - for not only was the span greater than almost anything else in the then-revered Plans Handbook, the low aspect ratio and long fuselage meant that it dwarfed lesser designs.
And yet, this was NOT the original Leprechaun: that honour fell to a model just one third the size of the published design, while Leprechaun Two as presented here, was designed in 1949 as a twice-sized version of the original, giving a much more manageable size. After all, at the time the big Leprechaun was built, Dick Twomey was an 18-year old schoolboy, and his transport was simply a bicycle, though he did later graduate to a Fiat 2-seater. Still not the best way to transport the big 'un!
Incidentally, there were five different 'Leps' in total: in addition to those already mentioned; there was a one-and-a-half and a two-and-a-half times version designed between June and September 1949. Leprechaun Two has a similar wingspan to an A/2 glider of that period, but with its 6:1 aspect ratio, a lot more wing area!
Events like National Service in the RAF conspired to pigeonhole large model aeroplane flying, though Dick continued to fly smaller models. While a fifty year wait between design and publication may seem a little excessive, at least you can build one safe in the knowledge that it is proven. And that the Society of Antique Modellers 'SAM 1066' confirm that it is eligible to compete in their Vintage flying events. There's even a Leprechaun Trophy to be competed for..."

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

User commentsWhere is the fuselage top view?

I think it's safe to say there never was a top view. The plan certainly says on it (next to S8): "Fuselage outside width 2=1/2 in between frames S4 and S8" which gives us a useful starting point, and I guess we are expected to work out the rest for ourselves. Back from there to the tail, it is a tapered box, essentially. I doubt anything inbetween S8 and the tail is at all critical.

* 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.
