Combat Gremlin - RC combat model. Flying wing design for .25 power.
Quote: "Combat Gremlin. A Flying Wing Combat Design. By Eric Henderson.
The Concept. For many years Control Line Combat has been recognized as a tremendously exciting form of contest. Combat addresses a primeval and very human appetite for one-on-one dueling. The Combat Gremlin has given R/C Combat a major shot of viability and has addressed the two major stumbling blocks of expense and building time.
It began with the thought that R/C flying is theoretically a non-contact sport. Therefore, how about designing a plane that is regularly expected to make some form of pretty hard contact? Several trainers were considered, seeing as how the toughness need has already been achieved with a couple of notables. The problem with this approach was that either they cost a lot of money or, to put it politely, they lacked acrobatic performance. Even a tough trainer has too many parts compared to a U-control set-up. What I was looking for was an acrobatic plane that would meet the rigors of combat. A plane that could almost always be field repaired. What I wanted was something that was as good as the U-Control crowd had!
Many hours were spent wrestling with the design concepts, but I consistently tripped over my accumulated model building experience. Boy! was I conditioned to build and design in a very narrow corridor. In the end I wrote a sign and hung it up above my workbench. It said. "If you build it, they will break it!" A play on words from the movie 'Field of Dreams. This freed up my thinking patterns and the Combat Gremlin was conceived.
The Design. The Combat Gremlin was designed from 'Impact' backwards. It had to bend rather than break. It had to allow every part to be field replaceable. The end result was a plane that was light and forgiving. It employed a self-contained fuselage that was attached to a semi-disposable wing. A flying wing was chosen because it has fewer bits to break.
Figure 1 shows the basic layout. The fuselage contained all the delicate parts and can be removed by only unscrewing three wing bolts and the disconnection of two clevises. It would prove to be very quick to make. With base materials such as plastic down-pipe and 2 inch insulation foam, it would also prove to be very inexpensive to make.
The engine chosen was the O.S. 25 plain bearing FP. Any equivalent plain bearing engine will do... "

* 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.
