Flight safety is one thing all pilots talk about. They Are living it, settle for it, and usually hope to decide on it in their day-to-working day lives in the aviation environment. With the Super Cub fanatic, the Prolonged Slotted Wing from Dakota Cub offers pilots the chance to greatly enhance their security margin and also boosting the climb overall performance of the plane.

Envision traveling your Super Cub at a superior angle of attack with the airspeed indicator looking through twenty mph, then rolling into sixty-degrees of bank and initiating a climbing spiral though choosing a power location that’s fewer than whole throttle! Which is The standard exhibition that sells the Dakota Cub Extended Slotted Wing. The 2nd most talked about high quality of this wing is a chance to have full flight Manage authority at substantial angles of attack. No more delicate controls, plopping it down, or wing drop on stall.

Mark Erickson, the founding father of Dakota Cub, began his mission while in the 1990’s. All he desired was a Cub rib. Nothing from Piper was obtainable at an inexpensive Expense and Because the Piper ribs were being so fragile, he chose to Construct his very own. He applied fashionable-working day technological know-how to an aged Piper wing which was initially designed for the YL-14 liaison Edition on the J5C Cub. The YL-fourteen wing was a slotted wing. Based on Erickson, there were only 14 of such aircraft developed prior to the stop of Planet War two. They were exclusively engineered for brief consider-offs of 100-ft and climbs with higher angles of assault. You will find only two of these nonetheless in the air currently – one in Spain; one other in Nebraska.

The Dakota Cub Prolonged Slotted Wing has numerous variances when compared to the initial Cub wing and also the L-14 wing for instance. Erickson revised the original Piper US35B airfoil utilized for the L-14. He made a customized “T” shaped extrusion With all the similar Proportions that when used in creating a truss-fashion rib, is lighter, less complicated to operate with, and much more robust than the initial wing. Erickson obtained a STC for the new wing in 1993.

Erickson’s new rib only provides 7 lbs to the load of each and every original Superslot Piper wing. The brand new wing has long been structurally analyzed to in obtain of 2,200 lbs, however, the STC boundaries the gross bodyweight to one,750 lbs for the initial wing or two,000 lbs for the people wings equipped With all the Wipaire One Ton Cub STC. This synthetic reduction will with any luck , be improved Sooner or later. Inside the intervening decades, Erickson has made ribs and many other elements which are FAA PMA-ed for all rag-wing Pipers. Erickson was granted the STC for the total-length main edge slot in 1998. This slot assists preserve the boundary layer of airflow at gradual speeds. In addition to that, Erickson engineered a squared off wing and got rid of the suggestion bow giving the wing an extra 6% surface location, amplified the flaps which results in 44% more flap area, and pushed the ailerons outward 23-inches to the edge on the wing. He phone calls it the “Prolonged Wing.” The squared wing adds about eight lbs to the first Piper wing.

Introducing a slot towards the Extended Wing adds A further 9 lbs for each wing, even so the elevated security envelope from which to fly is very well definitely worth the trade-off. The flight traits in the squared-off and slotted wing, which Erickson calls the “Extended Slotted Wing”, is the primary benefit and emphasis with regard to decision of wings to include with your Cub venture. The Extended Slotted Wing is the greatest carrying out wing offered by Dakota Cub. It’s got a 135-inch slot, a squared-off wing with 102-inch ailerons, plus a 90.25-inch flap. Dakota Cub also offers the normal Cub wing and also a squared-off wing without the slot.

The Extended Slotted Wing is just a safer wing. It permits a higher critical angle of attack, slower stall velocity, and almost eliminates the unexpected loss of raise rather than a straight wing. It delays the separation on the air move with the wing surface, Hence aileron authority is maintained and in several conditions the only real indication of a stall will be a greater-than-ordinary price of first rate. This phenomenon lets the sink price from the plane on method of landing to get controlled by electricity on your own enabling a far more exact touchdown stage with no anxiety of the wing stalling or slipping off on one aspect. The wing also has an enhanced roll charge a result of the ailerons remaining extended to the tip on the wing.

If you wish to choose entire benefit of the Extended Slotted Wing on your Tremendous Cub, then it is suggested to setup a 3-inch equipment extension. The equipment extension will allow the sluggish speed abilities of the wing to choose complete impact upon landing. Much larger tires will deliver for this too. Short equipment coupled with small tires will bring about tail wheel 1st landings and also a acquire-off operate that is definitely for a longer time than best because it’s more difficult to realize that better angle of attack.
