About this Plan
Caudron C635 Simoun - free flight rubber model.
Quote: "Rubber scale is perhaps the hardest fought event at the Nats. This ship won in 1980
This model should not be considered a beginner's project due mainly to the scale detailing required, but construction is straightforward and a relatively inexperienced builder should be able to achieve a good flying aircraft. It is designed from the start with AMA outdoor scale rules in mind. For those who fly mostly FAG rules, you will find the Caudron lacking in sufficient handicap points for serious competition. The moments are good, the size is large enough to be less touchy in trimming, and there is plenty of room for a fully wound rubber motor. The landing gear is well placed for good takeoffs and allows a rugged mounting design.
The only changes I make from scale, are to enlarge the stab a few percent, double the dihedral angle, and lengthen the landing gear just a trifle. The prototype flies very stably and may even work with everything to scale, although you're on your own here since I haven't tried anything but what's shown.
There is one factor which should be kept upper most in your mind while building and that is: lightness. You won't need to use anything but the four to six pound per cubic foot balsa. Don't add a harder piece here or there for more strength; this design will be strong enough if you use the lightest of material..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
