Jodel D.9 Bebe (oz6939)
About this Plan
Jodel D9 Bebe - Free flight scale model.
Quote: "Like many ardent scale modellers, Ho Fang-Chiun, a Chinese resident in Sweden was greatly attracted by contributor George Cull's description of the Jodel Bebe in our issue for April '54. Rough calculations showed that a ten-times enlargement of the 1/72nd scale plan would give 275 sq in wing area and a span of 38-1/2in - making it an ideal project for engines of .5 to 1cc. Webra diesels are freely available in Sweden, so one of the little Piccolo .8cc radially mounted engines was selected for the prototype. After early flight tests when dihedral was increased slightly more than scale, the Bebe was soon delighting the residents with its smooth and very scale-like mannerisms in flight.
Ho Fang-Chiun boldy eliminated all thought of a pendulum operated rudder and had no trouble at all with the soft aluminium tab adjustment shown on the plan. However, to satisfy the many British modellers who prefer a pendulum rudder as a margin of safety, he provides alternative details of such a rudder, using the system already proven so successful on the popular APS Dart Kitten (oz1635). Similarly, the drawing caters for the more common beam mounted engines, whilst Piccolo operators can still use the main bulkhead F.2 as a base for their radial mount."

* 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.
