Standard Plank (oz6229)
About this Plan
Standard Plank. Sailplane for RC. 100in span, 1090 sq. in area, for .049-.09 power (optional) and 2 channel RC.
Quote: "The Standard Plank is the continuation of a design series on flying wings and is the second design from the series to be published. The Little Plank (oz5163) was featured in the May 1972 RCM and, judging from the correspondence received, was well accepted both here and abroad. The current design is an attempt to improve performance for thermal soaring while retaining the simplicity and ease of construction inherent with the Plank configuration. A new wing section was developed based on the NACA 6409 and the aspect ratio was increased to ten. Control installation was simplified through the use of elevator and rudder. Design Summary: Configuration: Flying wing with no sweep and a constant wing section allowing the use of a single rib size. Fuselage: Minimum cross section with a single internal bulkhead. Rudder: Flying rudder utilizing an aluminum tube hinge. Power: .049 to .051 in a power pod, easily removed for slope or tow launch. Prototype used a Cox TD .051. Controls: Elevator and rudder. Wing Section: CJ-2, a section developed by the authors for use on flying wings and based on the NACA 6409 used on the Olympic 99 and other R/C gliders. Wing: Two piece with integral or plug in tips. Basic span of 100 inches may be extended with alternate tips."

* 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.
