Ahh yes, the "big wing theory". If you take the height of your wing, multiply it by the weight of the wing, then add 347,502....that will be your new top speed. The yellow rim's only have an effect on its ability to "raise up" (like Inspector Gadget). The turbo charged .05 litre engine, makes it as loud as a lawn mower, but the speed is already factored into the "Wing Equation"
