About this Plan
Bebe Jodel D9. Radio control sport scale model for .40 power.
Quote: "Here's another lively near-scale sport model -span 58 inch, for up to .40 power. Bebe Jodel, by Keith Humber.
HERE IS a simple near-scale rough field sports model, for all those who want something that 'looks like the real thing' yet which has a sparkling performance. It was originally brought into being by the need of a model to fly quickly - an acute shortage having been caused by low inverted runs getting a bit too low (6 in under-ground, in fact). However, out of misfortune sometimes cometh good - and the Jodel has certainly turned out to be a really good.
My original is powered with a K & B 40F (the Perry carb one), but if the structure is kept light, anything from a .29 would do comfortably. In fact, a great deal of the time one is flying on half throttle so as to keep the speed a little more realistic - on full throttle with the 40 she really goes, and uses up a lot of sky.
I don't think I would recommend this model to the out-and-out tyro, even though the construction is simple (don't worry, Keith—the tyro always wants to build a Lancaster com-plete with retract gear for his first model! - Eds). It is perhaps a little sensitive on elevator so, if anything, keep the CG a little ahead of my indicated position, to start with. With the CG as shown, though, she is just right for me (and if I can fly it, almost anyone can). I think that keep-ing the weight down is important with this machine. The proto-type weighed 5 lb, all-up, which included !).lb. of lead in the nose (I always seem to build tail-heavy!) so keep that tail end just as light as practical.
Construction Notes. I think that most of the construction is quite straightforward, and that any modeller who wants to build the Jodel would be quite capable of doing so without my interference, so I will simply point out the odd bits and pieces of note, here and there. Like the short engine bearers which enable the tank (6 oz square type), receiver, Deac and foam packing, to go in front of the cockpit. This leaves space for a proper pilot, but does tend to give a little trouble getting the fuel pipes through the firewall. They can be threaded through by inserting, temporarily, a piece of piano wire..."

* 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.
