Mark Erickson, the founding father of Dakota Cub, commenced his mission within the 1990’s. All he desired was a Cub rib. Nothing at all from Piper was accessible at an inexpensive Price tag and For the reason that Piper ribs have been so fragile, he decided to Create his very own. He used modern-day-day technologies to an previous Piper wing that was at first produced for your YL-14 liaison version with the J5C Cub. The YL-14 wing was a slotted wing. Based on Erickson, there were only fourteen of those aircraft created before the conclusion of World War 2. They have been specially engineered for brief acquire-offs of one hundred-toes and climbs with high angles of attack. You can find only two of those nonetheless from the air these days – one particular in Spain; another in Nebraska.

The Dakota Cub Extended Slotted Wing has various variances when compared to the original Cub wing plus the L-14 wing for instance. Erickson revised the original Piper US35B airfoil utilized for the L-fourteen.

Along with that, Erickson engineered a squared off wing and got rid of the suggestion bow offering the wing a further six% floor area, amplified the flaps which results in forty four% far more flap spot, and pushed the ailerons outward 23-inches to the edge from the wing. He phone calls it the “Prolonged Wing.” The squared wing provides about 8 lbs to the original Piper wing.

Incorporating a slot on the Prolonged Wing adds A further nine lbs for each wing, although the improved security envelope from which to fly is well definitely worth the trade-off.
