RES-Maxx

The 100-inch RES-Maxx is a rugged glider designed for the RES class, featuring lightweight construction and excellent thermal performance.

Amazing Rubber Hinges

OVER THE PAST FEW years, my experiments with the use of flat surgical rubber for hinging ailerons, flaps, elevator, and rudder on model Sailplanes have proven highly successful. The aircraft, a dozen or so in number, have ranged from competition thermal ships to racing birds flown in 50 mph winds. Working out the proper steps for installing the hinges has involved considerable trial and error. With these years of field experience now behind me, I'm convinced that this superior-quality rubber makes a most practical and fine-working hinge offering a wide range of RC application.

Orca

Name a model after the killer whale, known in the Pacific Northwest as Orca, and you've set up some pretty tall expectations. This airplane delivers. With the characteristic black-and-white markings and an airframe echoing the shape of the great porpoise that inspired it, Orca is as potent and gutsy a Slope Soarer as you could ask for. A terrific scratch-built project, Orca is a fearless, fast, and dedicated Sloper that's capable of high-speed work in quite strong winds. It's rock stable on the slope, handles easily, and responds beautifully to controls. The model uses the E374 airfoil slimmed down to 7.5%. Even without ballasting, penetration is superior in winds up to about 35mph.

Roto Raven

IN THE WORLD of high-performance Thermal Soaring, Roto-Flap is new, challenging, and exciting. A highly effective and practical system of control for the Thermal Soarer, it may provide a basis for developing a new generation of sophisticated Soaring machines yielding unprecedented performance levels. The boxy Roto-Raven is a quick and easy way to get acquainted with Roto-Flap while amply demonstrating the system's viability and potential.
