Flight protection is one thing all pilots speak about. They Dwell it, settle for it, and normally hope to select it of their day-to-day lives from the aviation globe. For your Super Cub fanatic, the Extended Slotted Wing from Dakota Cub offers pilots the chance to boost their security margin as well as boosting the climb performance in the aircraft.

Picture flying your Super Cub at a large angle of assault Along with the airspeed indicator looking at 20 mph, then rolling into sixty-levels of bank and initiating a climbing spiral when selecting an influence setting that is less than total throttle! That is certainly The standard exhibition that sells the Dakota Cub Prolonged Slotted Wing. The 2nd most mentioned high quality of the wing is the opportunity to have whole flight Handle authority at significant angles of assault. No far more tender controls, plopping it down, or wing fall on stall.

Mark Erickson, the founder of Dakota Cub, started his mission during the 1990’s. All he desired was a Cub rib. Very little from Piper was obtainable at a slot pg reasonable Expense and Considering that the Piper ribs have been so fragile, he decided to Create his individual. He utilized modern day-day technological know-how to an outdated Piper wing which was originally produced to the YL-14 liaison Variation in the J5C Cub. The YL-14 wing was a slotted wing. As outlined by Erickson, there have been only 14 of those aircraft crafted ahead of the end of Earth War two. They were specially engineered for short just take-offs of 100-feet and climbs with significant angles of attack. You will find only two of such even now from the air now – a person in Spain; one other in Nebraska.

The Dakota Cub Prolonged Slotted Wing has many variances when put next to the first Cub wing along with the L-14 wing for that matter. Erickson revised the original Piper US35B airfoil employed for the L-14. He developed a tailor made “T” shaped extrusion With all the exact Proportions that when Employed in creating a truss-fashion rib, is lighter, easier to operate with, and even more strong than the initial wing. Erickson acquired a STC for The brand new wing in 1993.

Erickson’s new rib only provides seven lbs to the load of every authentic Piper wing. The brand new wing has been structurally tested to in accessibility of 2,200 lbs, however, the STC boundaries the gross bodyweight to one,750 lbs for the initial wing or two,000 lbs for people wings Geared up While using the Wipaire 1 Ton Cub STC. This artificial reduction will hopefully be modified Sooner or later. Within the intervening a long time, Erickson has made ribs and all kinds of other elements that happen to be FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the total-length main edge slot in 1998. This slot allows preserve the boundary layer of airflow at gradual speeds. In addition to that, Erickson engineered a squared off wing and removed the tip bow providing the wing yet another six% floor spot, amplified the flaps which results in forty four% more flap region, and pushed the ailerons outward 23-inches to the sting with the wing. He calls it the “Extended Wing.” The squared wing provides about eight lbs to the initial Piper wing.

Incorporating a slot for the Prolonged Wing provides A further nine lbs for each wing, but the greater safety envelope from which to fly is well worth the trade-off. The flight attributes in the squared-off and slotted wing, which Erickson calls the “Prolonged Slotted Wing”, is the principal benefit and emphasis regarding choice of wings to incorporate in your Cub project. The Extended Slotted Wing is the greatest accomplishing wing supplied by Dakota Cub. It’s a 135-inch slot, a squared-off wing with 102-inch ailerons, along with a 90.25-inch flap. Dakota Cub also offers the normal Cub wing as well as a squared-off wing without the slot.

The Extended Slotted Wing is just a safer wing. It permits a higher critical angle of assault, slower stall velocity, and pretty much gets rid of the unexpected lack of lift versus a straight wing. It delays the separation of your air stream from your wing surface, Therefore aileron authority is preserved and in many situations the only real indicator of a stall will be a higher-than-usual amount of decent. This phenomenon will allow the sink price of the plane on approach to landing being managed by energy alone enabling a more exact touchdown issue without having panic of a wing stalling or slipping off on a person side. The wing also has an enhanced roll price due to the ailerons currently being prolonged to the tip of your wing.

If you would like take entire advantage of the Prolonged Slotted Wing on your own Tremendous Cub, then it is recommended to setup a three-inch equipment extension. The gear extension will allow the slow velocity abilities of your wing to acquire whole result upon landing. Larger sized tires will provide for this likewise. Limited equipment coupled with little tires will end in tail wheel initially landings plus a choose-off run that’s more time than ideal because it’s tougher to achieve that increased angle of attack.
