Cardinal - Semi-scale rudder only RC model. Wingspan 44in, wing area 316 sq in, for .049 engines.
Quote:- "The Cardinal was designed around a Bonner VariComp and a Cox Tee Dee or Medallion .049 - the most important consideration being an attempt to produce a good, fast-building sport rudder-only ship with no sacrifice in strength, yet one that would be something more than the run-of-the-mill flying box. Since the Cardinal appeared on the cover of the December issue of R/C Modeler, a host of letters have been received asking for plans and construction details on this ship - makes me believe that there are others who are ready for a departure from the everyday designs. With the aforementioned Tee Dee .049, the Cardinal flies fairly fast and with excellent wind penetration. The first flights were made on a windy day and a stall was immediately apparent. A 3/32" shim under the trailing edge of the wing corrected this condition and subsequent flights were made without mishap. This shim should be removed in calm weather. If you feel that the Cardinal is the change-of-pace Sunday flier you've been looking for (it'll fly on weekdays as well), order a set of plans, read the instructions through twice, and you're on your way!"

* 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.
