Part 5. Good spar materials include wooden dowels and carbon fiber (aka: graphite) arrow shafts. Prices range from US$2-3 for wood dowels and US$3-7 for arrows at Wal-Mart, Cabelas, and others. Dowels are widely available and easy to work with. Carbon arrows are light, very durable, and joinable by threaded inserts.
An easy and economical method of building an actual airfoil for an RC airplane wing out of inexpensive foamboard, hot glue, and packing tape. Almost as easy to make and much better lift and stall characteristics than a KF or flat-plate wing. This is just the wing construction - overall airplane design is up to the builder! I hope to see some innovative airplanes using this wing design.
