Dakota Cub’s Extended Slotted Wing

Flight safety is something all pilots speak about. They live it, accept it, and always hope to choose it in their day-to-day lives in the aviation world. For the Super Cub fanatic, the Extended Slotted Wing from Dakota Cub offers pilots the opportunity to enhance their safety margin as well as boosting the climb performance of the aircraft.

Imagine flying your Super Cub at a high angle of attack with the airspeed indicator reading 20 mph, then rolling into 60-degrees of bank and initiating a climbing spiral while selecting a power setting that’s less than full throttle! That is the typical exhibition that sells the Dakota Cub Extended Slotted Wing. The second most talked about quality of this wing is the ability to have full flight control authority at high angles of attack. No more soft controls, plopping it down, or wing drop on stall.

Mark Erickson, the founder of Dakota Cub, began his mission in the 1990’s. All he wanted was a Cub rib. Nothing from Piper was available at a reasonable cost and since the Piper ribs were so fragile, he decided to build his own. He applied modern-day technology to an old Piper wing that was originally developed for the YL-14 liaison version of the J5C Cub. The YL-14 wing was a slotted wing. According to Erickson, there were only 14 of these aircraft built before the end of World War 2. They were specifically engineered for short take-offs of 100-feet and climbs with high angles of attack. There are only two of these still in the air today – one in Spain; the other in Nebraska.

The Dakota Cub Extended Slotted Wing has several variances when compared to the original Cub wing and the L-14 wing for that matter. Erickson revised the original Piper US35B airfoil used for the L-14. He developed a custom “T” shaped extrusion with the same dimensions that when used in building a truss-style rib, is lighter, simpler to work with, and more robust than the original wing. Erickson obtained a STC for the new wing in 1993.
