Flight security is something all pilots talk about. They live it, acknowledge it, and consistently desire to pick it in their everyday lives in the flight world. For the Super Cub devotee, the Extended Slotted Wing from Dakota Cub offers pilots the amazing chance to improve their security edge as well as helping the trip execution of the airplane.
Envision flying your Super Cub at a high approach with the velocity pointer perusing 20 mph, then moving into 60-levels of bank and starting a climbing winding while at the same time choosing a power setting that is not exactly max speed! That is the commonplace show that sells the Dakota Cub Extended Slotted Wing. The second generally discussed nature of this wing is the capacity to have full flight control authority at high approaches. Not any more delicate controls, thudding it down, or wing drop on slow down.
Mark Erickson, the pioneer behind Dakota Cub, started his central goal in the 1990’s. All he needed was a Cub rib. Nothing from Piper was accessible at a sensible expense and since the Piper ribs were so delicate, he chose to construct his own. He applied advanced innovation to jumboslot888 an old Piper wing that was initially produced for the YL-14 contact variant of the J5C Cub. The YL-14 wing was an opened wing. As indicated by Erickson, there were just 14 of these airplanes worked before the finish of World War 2. They were explicitly designed for short departures of 100-feet and moves with high approaches. There are just two of these still in the air today – one in Spain; the other in Nebraska.
The Dakota Cub Extended Slotted Wing has a few changes when contrasted with the first Cub wing and the L-14 wing besides. Erickson updated the first Piper US35B airfoil utilized for the L-14. He fostered a custom “T” molded expulsion with the very aspects that when utilized in building a bracket style rib, is lighter, easier to work with, and more strong than the first wing. Erickson got a STC for the new wing in 1993.
Erickson’s new rib just adds seven lbs to the heaviness of every unique Piper wing. The new wing has been fundamentally tried to in access of 2,200 lbs, nonetheless, as far as possible the gross load to 1,750 lbs for the first wing or 2,000 lbs for those wings furnished with the Wipaire One Ton Cub STC. This fake decrease will ideally be changed from here on out. In the mediating years, Erickson has planned ribs and numerous different parts that are FAA PMA-ed for all cloth wing Pipers. Erickson was conceded the STC for the full-length driving edge opening in 1998. This opening assists safeguard the limit with layering of wind stream at slow paces. Additionally, Erickson designed a made right wing and disposed of the tip bow giving the wing an extra 6% surface region, expanded the folds which brings about 44% more fold region, and drove the ailerons outward 23-creeps to the brink of the wing. He considers it the “Expanded Wing.” The squared wing adds around 8 lbs to the first Piper wing.
Adding an opening to the Extended Wing adds another nine lbs for every wing, except the expanded security envelope from which to fly is definitely worth the compromise. The flight qualities of the got down to business and opened wing, which Erickson calls the “Broadened Slotted Wing”, is the essential benefit and accentuation concerning selection of wings to remember for your Cub project. The Extended Slotted Wing is the best performing wing presented by Dakota Cub. It has a 135-inch opening, a made right wing with 102-inch ailerons, and a 90.25-inch fold. Dakota Cub likewise offers the standard Cub wing and a made right wing without the opening.
The Extended Slotted Wing is just a more secure wing. It allows a higher basic approach, more slow down speed, and essentially disposes of the unexpected loss of lift rather than a straight wing. It postpones the partition of the wind stream from the wing surface, hence aileron authority is kept up with and by and large the main indication of a slow down will be a higher-than-typical pace of fair. This peculiarity permits the sink pace of the airplane on way to deal with arriving to be constrained by power alone empowering a more exact score point unafraid of a wing slowing down or tumbling off on one side. The wing additionally has a superior roll rate because of the ailerons being stretched out to the furthest limit of the wing.
If you have any desire to make the most of the Extended Slotted Wing on your Super Cub, then, at that point, it is prescribed to introduce a 3-inch gear expansion. The stuff augmentation will permit the sluggish speed capacities of the wing to produce full results after landing. Bigger tires will accommodate this also. Short stuff combined with little tires will bring about tail wheel first arrivals and a take-off run that is longer than ideal since accomplishing that higher approach is more troublesome.
The outcome of this development is a Cub that has better trip execution, better sink control, more slow arrivals, and a lot more noteworthy room for error of security. A wide-body fuselage from Airframes, Inc includes a drawn out fuselage, and when joined with the bigger control surfaces and the opening, a pilot can fly at a 45-degree nose-up disposition, land at 25 bunches, despite everything have a wing that lingers palpably.
The Dakota Cub opened wing gives the best lift, slow flight, and slow down execution of any wing accessible for the Super Cub and it’s the main wing of its sort to be given a STC (Supplemental Type Certificate).
