Pulstar. Simple all-sheet sport model for .020 power and single channel (pulse) RC.
Quote: "Pulstar. Try a suitcase model, free-flight or radio control, Vic Smeed's 27 inch, all-sheet model for 0.20 cu in engines will provide hours of fun.
Have you ever gone out for a flying session and broken some vital part or run batteries flat, and wished you had something else to fly? Do you remember pulse? Here's aquickly-built miniature which takes up no room to speak of in the car, costs very little in time or cash, but is capable of providing enormous fun. It can be flown with certain types of lightweight radio or as a free-flight model; the original, flown manual pulse, was handed over to an enthusiast who literally wore it out with hours and hours of flying.
On the original, a TO3 motor gearbox was used as an actuator, but any efficient, low-drain small motor can be used, with a coiuple of gears from a discarded servo. Alternatives are one of the very small rubber-driven escapements such as the Futaba (with the rubber run along the fuselage side), and American Rand miniature pulse unit, or even one of the modern very light miniaturised servos used conventionally.
Power is a Cox .010 (if you still have one!) or a .020 but a free-flight version flew very successfully with a Wasp .049. If you go for this size, use an inefficient prop, at least for the initial flights..."

* 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.
