They wouldn't be hard to build, I have a ton of pictures and the owner of the Lambo service shop by my house has an Aventador I can look at any time for reference and dimensioning.
That flyboard is crazy btw. Don't kill yourself with it.
Heres my car at the shop with some other lambo's. They do my oil changes and other service there. Do you guys recognize the yellow LP670? One hint, it has a Polish license plate on it.............and its aftermarket 670 parts.
Anyway, back on topic dammit! (sorry Rob) lol.
