    Default Price reduction: APR molded wing elements

    One high quality brand new APR molded carbon fiber wing element.
    Big price reduction.
    Just a small fraction of the over $600 mfg.cost per element
    These are moulded, not wire cut.
    Hollow inside with thin wall carbon fiber strengthening spars across the span and CF end ribs with epoxied in nutserts.
    Nice sharp thin well defined trailing edges.
    Can be used for front wings. Usually always survive high speed direct cone hits with no cracks. I cut a cone in half at 65 Mph with my old front wing built like with this part number.

    Could add the popular 4” cord APR flap as next element or run the 10” cords together
    Could also be trimmed easily to use as a B-Modified formula car rear wing assembly. You would use these new end caps below after trimming the element span if the old end caps cannot be re-used (but usually they are)
    1 Brand new, Carbon Fiber, 54.5” span
    10" cord
    $350 dropped to $175.
    5 lbs. 12-5/8 oz. each


    The last picture shows how a typical bottom mount is made. Just 2 curved pieces of aluminum using 3/16" rivets up into the element.
    Or they can be supported only by the end plates.

    So these are designed to be end mounted, not center?

    Either way.
    I had a 4-element assembly where some elements just like this were supported by their ends and then one element had a lower support. The other elements' loads came back to it through the endplates.
