About this Plan
Rascal. Wakefield class free flight rubber contest model.
Quote: "By Claude McCullough. An American Wakefield model capable of high climb, fast glide and meet-winning time.
Events for this class being held at many big regional meets, interest again turns to 200 sq in jobs after a rash of super big crates ranging up to 400 sq in. Much more convenient to fly and carry, a 200 sq incher gives away little to big ships in the way of performance. In addition, you don't need Man Mountain Dean on the winder to get in those last few turns.
The Rascal is strictly in the American Wake tradition, a little on the boxy side, strong simple construction, no unnecessary frills or frippery and designed to pack a whopping rope of rubber for a quick climb to thermal country.
The high angle of climb is a aided by the use of thin low-drag wing section, a setup that gave such spectacular results for many of the experts at the Nationals.
The original Rascal uses 28 strands of 3/16 T-56 brown rubber, and turns out a climb that would make a Zipper envious. If you are really looking for a jet-propelled take-off, a few more strands will give it, although at the cost of a few winds. Built-in downthrust (positive stabilizer) helps to control all of the power you can pack in.
Altitude is what you are shooting for; ground huggers seldom bring-home the money at a contest. Tiring of having the covering punctured like an archery target after a few flights, we used silk on the entire ship. You needn't raise your eyebrows. We hasten to explain that the ship turned out only 3/4 ounce over the required weight of 8 oz..."
Supplementary file notes
Alternate version of the same plan, thanks to Sherlock. This one shows formers and ribs at full size.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
