    The fins on the Colossus are (were) the same as the ones on the Maxi Alpha 3.
    The Executioner fins were through the wall plywood.
    The Colossus/Maxi Alpha 3 fins were plastic.
    Don't know if the dimensions were the same but templates for the Executioner are here:

    And templates for the Maxi Alpha 3 are here:

    You can print both out and compare.

    Thanks, just by looking closer at the two of them I can tell they are different dimensions.

    Literally, the same. Not just the same size.

    If you are considering cloning the Colossus, go with wood fins that have the same profile.

    Just remember to never let your Colossus talk to your Guardian.

    Lynell got it instantly when I told her verbally after the launch on Saturday.

    Just for future reference the Executioner fins are not the same dimensions as the Colossus fins.

    Be very glad that the Colossus fins aren't Kronos fins.

    Executioner Fins are DIFFERENT shape than Colossus Fins. The Executioner fins are longer and more sweptback.
