Dollar Store Foam board Flying Wings

Published on 28 Mar 2012
GENERAL DETAILS AND BUILD TIPS:
There are many versions of the beloved flying wing. This particular model is made from a single piece of Dollar store foamboard, pre-covered with packing tape, and assembled with hot glue and two-sided foam tape. Its mission is to go very fast with a medium-sized powerplant and 3-cell battery pack. It is easy to build, with only two straight wing cuts, two hinge cuts, and two score-fold-glue joints for the vertical stabilizers. The scale and style factor is pretty humble in order to keep the weight down and the build simple, but it can be made to look relatively cool enough with some nice colored packing tape. Wingspan 21", length 19", AUW 500-650g, speed 60-75mph. I have used 1100kV and 1500kV 70g, 330 watt +/- motors with 8x6 APC props and 3-cell 2200mAh battery packs and gotten very respectable performance. A 2200kV with 6x4 and a 1300mAh pack was 400g and pretty quick as well. One could use a higher kV rating and/or cell count for faster speeds. 64mm EDF works very well too, mounted on top, with a paper cup thrust tube. These can be very fast and nimble with a roll rate over 1000 degrees per second, so I would recommend having at least intermediate skills and low rates to start. Launch 1/2 throttle at 30 degree up-angle and trim while at altitude. The EDF does well with landing gear (nose wheel, tail skids).

MiG-29 V3: Our Fastest Design Ever!

Thinking Outside the Box

"thinking outside the box"

The material in this book is a compilation of computer generated images, hand generated sketches  and engineering data, gleaned from hundreds of pages of documentation in the public domain, about the many research projects conducted in Germany through the course of the second world war. Most of the aircraft under development were constructed of non strategic materials, such as wood and composites. As the end approaches in 1945 the projects take on an ever increasing tone of desperation, which is reflected in the extremely non conventional nature of the aircraft designs. The engineers and scientists working on these research projects were to use a modern phrase "thinking outside of the box". The flight testing aspect of these radical designs were extremely dangerous to the flight crews, who incidentally were in a large part women. All of the experienced pilots were engaged in operational duties and could not be spared for test pilot duties. Many of the projects were destroyed in bombing raids by the quickly advancing Allied forces and their existence would have been obliterated from history had it not been for the teams of engineers and scientists who were tasked to gather information by interviewing the personnel who worked on these projects. The volunteers at Luft '46 are dedicated to the preservation of this aeronautical history​
