Apparently the buggy is called a Protech Enigma in europe, and there is a pro version thats called the Enigma XR. Yusa sold this buggy as a RTR called the B240. It looks like this RTR was/ is only sold in southeast asia. There is an updated version (maxx style front pivot ball suspension, laydown steering servo) of the rollers we bought that is sold here as the RD logics SHO, and as a "Swift" under various brands (power racing, prp, nanda). So im betting we can use most of the rd logics rear suspension and chassis parts on our yusas.
