Flight protection is one thing all pilots speak about. They live it, take it, and generally hope to choose it of their day-to-day life inside the aviation entire world. For your Tremendous Cub fanatic, the Prolonged Slotted Wing from Dakota Cub provides pilots the chance to improve their basic safety margin and boosting the climb general performance from the plane.
Visualize traveling your Tremendous Cub at a significant angle of assault Along with the airspeed indicator reading through 20 mph, then rolling into 60-degrees of bank and initiating a climbing spiral while deciding on an influence environment which is lower than complete throttle! That is definitely The standard exhibition that sells the Dakota Cub Prolonged Slotted Wing. The next most talked about quality of this wing is the ability to have whole flight Handle authority at substantial angles of assault. No more soft controls, plopping it down, or wing drop on stall.
Mark Erickson, the founding father of Dakota Cub, began his mission in the 1990’s. All he wished was a Cub rib. Nothing at all from Piper was accessible at slotsuper a reasonable Expense and For the reason that Piper ribs had been so fragile, he decided to build his own. He utilized modern-day technology to an previous Piper wing that was initially produced for your YL-14 liaison Model of your J5C Cub. The YL-14 wing was a slotted wing. In keeping with Erickson, there were only fourteen of those aircraft created before the conclusion of World War two. They were being precisely engineered for short take-offs of 100-toes and climbs with substantial angles of attack. You’ll find only two of these still during the air right now – just one in Spain; the opposite in Nebraska.
The Dakota Cub Prolonged Slotted Wing has many variances when put next to the first Cub wing and also the L-fourteen wing for that matter. Erickson revised the initial Piper US35B airfoil useful for the L-fourteen. He formulated a custom made “T” formed extrusion with the similar dimensions that when Utilized in creating a truss-design and style rib, is lighter, less difficult to operate with, and even more strong than the initial wing. Erickson attained a STC for the new wing in 1993.
Erickson’s new rib only provides 7 lbs to the load of each and every initial Piper wing. The brand new wing is structurally tested to in accessibility of two,two hundred lbs, on the other hand, the STC restrictions the gross excess weight to one,750 lbs for the original wing or two,000 lbs for all those wings equipped Together with the Wipaire One Ton Cub STC. This synthetic reduction will hopefully be modified Down the road. While in the intervening yrs, Erickson has intended ribs and all kinds of other elements which have been FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the full-duration top edge slot in 1998. This slot aids protect the boundary layer of airflow at sluggish speeds. Along with that, Erickson engineered a squared off wing and got rid of the tip bow offering the wing yet another six% surface space, increased the flaps which results in 44% far more flap space, and pushed the ailerons outward 23-inches to the sting in the wing. He calls it the “Prolonged Wing.” The squared wing provides about eight lbs to the initial Piper wing.
