Quote: "A unique .40 powered WWI aircraft that makes a great sport flier.

The 4C differed from the original Etrich design in having a more conventional tail layout, much less wire rigging, a simpler landing gear and large ailerons, making it a much cleaner design that is easier to develop into a stand-off scale model aircraft.

Nine years ago, I built a Balsa USA Taube, powered by an O.S. 40 4-stroke engine, which I have been flying ever since. The kit was very inexpensive and simple to build. The design was based on the original Etrich design of 1910. The model has delightful flying characteristics and is easy to fly. Six years ago, t was able to get a good 3-view of the Rumpler 4C Taube through correspondence with Col. John A. de Vries and Richard M. Zasadney. I developed the 4C design using the Balsa USA kit as a basis, employing many of its precut structural parts.

The resulting design has an entirely different tail, a modified landing gear, and fuselage, and a wing which employs a modified airfoil and ailerons. The tail control surfaces of the 4C were much larger than that of the Etrich, improving low speed maneuverability. As a result, the flight characteristics of the 4C showed an improvement over the original Balsa USA model in the areas of inverted flight, outside maneuvers, speed range, rolls, and spins. Although I like a model with scale-like appearance, I enjoy doing maneuvers beyond the capability of the full-scale aircraft. The model can do slow and snap rolls; inside, outside, and square loops; split S, tail slides; spins; Immelmanns, hammerhead stalls; horizontal, vertical, and Cuban eights; as well as inverted flight.

To achieve this performance, the model was designed to be strong and yet light. This was accomplished, in part, by using good quality light balsa wood and covering the model with Coverite's Micafilm. I recommend purchasing the Balsa USA Taube, which is a bargain, priced close to what the materials alone would cost. About 2/3 of the materials supplied in the kit can be used to build this design with minor or no modifications required for many of the precut and shaped parts..."
