Dyke
Delta
A 1960s delta homebuilt as a fast, easy 3D flying machine!
By Daniel Walton
Daniel designed and built this Peanut scale model of the Dyke Delta in 1985. It became the inspiration for the 3D Dyke Delta R/C model featured here.

he Dyke Delta Aerobatic Flyer pro- ject found its roots in a glimmer of inspiration at the Central Plains E- fly Spectacular in November of
2010. For years, flying wings and tailless aircraft have been an interest of mine. How- ever, most of the tailless and flying wing types that I knew of have their elevons out near the tips of the wings where they are way out of the prop blast. Not suitable for this type of flying. These planes require that the control sur-
faces be in the slipstream of the prop to fly properly and that lets out many of the tail- less and flying wing models of full size air- craft that are out there, but not all. One aircraft that I had built as a peanut
of years ago not only had all the control sur- faces in the slipstream, but also had them back as far as possible from the c.g., thus al- lowing potential control of a model in this mode of flight. With this glimmer of insight,
the idea was temporarily shelved until the experience level with this general type of model had been increased with the aid of a production kit. If you want more information on this type
of model it can be viewed at www.fancyfoam. com where you can find a lot of pertinent in- formation as well as pricing and accessory kits, servos, motors, tips and builder infor- mation, along with other links to information. I chose a commercially available kit as my
first experience to learn the materials and techniques before starting my own design so that I would have a known, flyable quantity as a background. The surest path to failure is to count on perfect success your first time out with an unknown number of design and fabrication factors as well as a strange con- figuration. I knew that there were a lot of different techniques that I would have to master in putting one of these aircraft to-
