1935 Taylor Cub E-2
The 1935 Taylor Cub Model E-2 is a scale model designed for .40 power with R/C assist.
Quote: "The resurgence of interest in free-flight scale models is undeniable. One need only observe the surge of activity in **P-Nut**, **Power**, and **Rubber Scale**, as well as the increasing number of entries in local and regional contests to recognize this phenomenon. Models are being constructed of every conceivable prototype, with less emphasis placed on absolute scale and intricate detail, focusing more on flying qualities.
While some builders showcase extraordinary skills in developing ultra-light, highly detailed models, the majority construct in a scale that provides personal satisfaction. The primary focus is on the enjoyment of creating and flying a model that is recognizable as a scaled representation of a specific prototype. This article is directed toward R/C modelers who appreciate the concept of "Silhouette Scale."
For several years, enthusiasts interested in the old-timer radio assist concept have speculated about the possibility of a Flying Scale event for these classic designs. Questions arose regarding how well the SAM rules could be applied to models, what performance profile the SAM 225 (sq per .10 cu inches of displacement) rule might create, and whether scale models could be designed with thermaling capabilities.
The concept revolves around free-flight scale models with R/C assist to simplify retrieval and extend in-sight thermaling. The model's silhouette should be recognizable, but significant emphasis would not be placed on strict scaling. Judging could be conducted using existing Free-Flight Scale Rules, combining scale fidelity with duration times. An even simpler method might utilize the Mooney Peanut system as outlined in the AMA rule book. This is not an attempt to establish new event rules; rather, the intent is to encourage involvement in an area rich with potential fun and a challenging new dimension.
Several free-flight scale models were published or kitted in the pre-WWII era, including Comet's Curtis Robin, Cleveland's Stinson Gull Wing, and the Rearwin Speedster, alongside numerous designs by Pant Lindberg. Many of these designs are well-suited for the Silhouette Scale concept; however, the decision was made to create a new design to better exploit modern tools and materials. A prototype full-scale aircraft from the pre-WWII era was selected, although the question remains whether old-timer R/C assist scale subjects should be confined to a specific timeframe, given the expansive options available.
The Prototype
The E-2 Cub was chosen for several reasons: primarily because it has not been published in a larger size, unlike its younger sibling, the J-3, which has many variations. Secondly, the distinct squared-off appearance of the E-2 is visually appealing. Lastly, there was a surprising revelation that the E-2 was not a cabin aircraft, as previously assumed, but rather an open-sided parasol design. This discovery provided an opportunity to explore a novel plug-in wing concept.
This model was designed to be built using power free-flight scale techniques. A quick review of the drawings indicates that the model resembles an oversized free-flight model with radio control added. Although it is significantly lighter and less complex than traditional R/C designs, the model is sufficiently strong and well-stressed in high-force areas. The choice of plug-in wings enables the development of a robust parasol wing mount without resorting to heavy structures or complicated wire-bending techniques.
