About this Plan

Witch Hawk 500. Free flight power model for .15 to .23 engines.

Quote: "Wanting a small, hot-climbing 1/2A job that would have a glide comparable to larger ships, Jim Clem designed the 237 sq in Witch Hawk (oz4466) in 1978 for Category II and III work. Since then its contest record has been phenomenal, winning scores of local and regional meets, and the Nationals in 1979. At the same time it was winning contests, the little Witch Hawk was setting national records in the hands of Bill Jenkins. It received NFFS Top Ten Design recognition for Jim in 1981.

Operating under the precept that 'if a little is good, then more must be better' Jim scaled up the 237 sq in model late in 1979 to the Witch Hawk 500 presented here. The precept proved to be accurate. The contest record of the bigger bird is no less impressive. Ranging from a first place at the 1980 Nats by Bill Dunlop to prestigious wins in 1981 at the Tulsa Glue Dobbers Annual Meet and the Huntsville Heart of Dixie Contest by Bill Jenkins, the Witch Hawk 500 is a bird of the same feather as its smaller nest mate.

Emphasizing the time-honored Jim Clem success formula best described as simplicity in action, the 500 builds quickly and accurately for any modeler, almost regardless of previous building experience. II is an excellent first choice airplane for anyone wanting to break into thc competition scene, as well as a potential Number One ship for the experienced competitor.

Contrsuction. Probably the best approach is to think of it as though it were a kit, instead of being scratch-built. In translation, the way to gho is to 'pre-kit' all of the necessary components befor starting the construction phase.

For the fuselage, the pieces you will nedd are the sides, top and bottom, pylon components, plywood engine pieces, and interior formers. The critrical pices for purposes of alignment are..."

Hi Steve, Mary: I am just about finished building a Witch Hawk 500 for the special event at the U.S. Nationals this year. I built it from this Model Aviation plan, which I've had for years, and I realized a mistake on the plan, too late to do anything about it. If you use the formers as drawn on the plan plus the top/bottom view as shown on the plan, you end up with a fuselage that is a quarter inch too wide because the MA draftsman (person) failed to allow for the width of the 1/8" sides. This is very obvious when I compare my new one to the version I built back in the 80s from the National Free Flight Society plan. I will send photos of the "fat fuselage version" when I finish covering it.

Notes

* 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.

Scaling

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.
