    Ok, I'm sure this group knows this off the top of their head... The Air Force has finished the rear wing (Looks awesome!) and was telling me they would like to add a wicker bill.
    I called Div 2 tech director Ryck Campbell for legal or not question, got the maybe not and then was referred to John Collins Top Alcohol Rule committee chair to get an answer. Well they’re all in Atlanta this week and next.

    Anyone know if I can run a 1/4 “wicker bill on the trailing edge of the wing?


    Thanks
    Jeff

    yes

    You can add a wicker to the wing no problem. The wicker may cause more drag than adding angle of attack. That's why you don't see them used much on blown dragsters. Most TAD wings stall around 5-7 degrees of attack, where they only produce more drag without more downforce.

    Hi Jeff,
    NHRA rulebook, section 11, page 197, Wings and supports second paragraph:
    Wicker permitted, maximum 1/4 inch.
    Question: Blown alcohol TAD or A/F ?
