Mark Erickson, the founder of Dakota Cub, began his mission within the 1990’s. All he wished was a Cub rib. Almost nothing from Piper was out there at an inexpensive cost and Because the Piper ribs ended up so fragile, he made a decision to Create his very own. He utilized present day-day technology to an outdated Piper wing which was at first made for your YL-14 liaison Model of your J5C Cub. The YL-fourteen wing was a slotted wing. In line with Erickson, there have been only fourteen of such aircraft constructed ahead of the finish of Entire world War 2. They ended up precisely engineered for brief just take-offs of 100-ft and climbs with large angles of attack. There are only two of such still within the air now – just one in Spain; the opposite in Nebraska.

The Dakota Cub Extended Slotted Wing has various variances in comparison to the original Cub wing as well as the L-fourteen wing for that matter. Erickson revised the original Piper US35B airfoil employed for the L-14. He made a customized “T” shaped extrusion Together with the identical dimensions that when Utilized in building a truss-design rib, is lighter, less complicated to operate with, and a lot more strong than the first wing. Erickson attained a STC for the new wing in 1993.

Erickson’s new rib only provides seven lbs to the weight of each and every first Piper wing. The brand new wing is structurally examined to in entry of 2,200 lbs, even so, the STC boundaries the gross body weight to one,750 lbs for the initial wing or two,000 lbs for anyone wings Outfitted Together with the Wipaire Just one Ton Cub STC. This artificial reduction will ideally be improved Later on. In the intervening many years, Erickson has made ribs and all kinds of other parts which are FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the total-size foremost edge slot in 1998. This slot allows protect the boundary layer of airflow at gradual speeds. On top of that, Erickson engineered a squared off wing and removed the suggestion bow offering the wing a further six% area spot, improved the flaps which ends up in 44% a lot more flap area, and pushed the ailerons outward 23-inches to the edge of your wing. He phone calls it the “Prolonged Wing.” The squared wing adds about 8 lbs to the initial Piper wing.
