Sultan - RC stunt model. 45-61 March-April 1961 AAM.
Quote: - "The Sultan design is my approach to an attractive, simple-to-build multi channel contest airplane. I am not saying that the Sultan is the absolute ultimate for contest work, but it is a design for your competitors to worry about. The background of the design concept might interest the reader. The Sultan was my first ship with full span ailerons. Correspondence with Hal deBolt prompted me to try this type.
After drawing up a rough set of plans, Sultan # I was built in one week. This proved out its simple-to-build features. The ship weighed 5-lbs, 6-oz. A Space Control radio system was utilized. The ship flew quite well but it had one serious fault. Directional stability was lacking in consecutive maneuvers such as loops. I overcame this by adding additional fin area. This solved the directional problem but created another. Because of the enlarged fin, it was difficult to accomplish spin maneuvers. I added more rudder and elevator area and the result was a positive spin maneuver.
Sultan #1 also was my first attempt at utilizing a full symmetrical airfoil section. The results were gratifying. Inside and outside loops were consistent in size. As you know, this is not usually the case with a semi-symmetrical airfoil... "
Update 10/01/2017: Have re-scaled this plan to correct fullsize. Still a low resolution plan, though.
Article pages, incomplete.
Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
