The TYCO 440 Magnum Chassis (1981)

While the Curvehugger HP2 chassis of 1980 was a pretty good chassis by the standards of the time, it suffered from one serious problem in terms of overall H.O. slotcar design. It was simply too bulky to use on modern Indycar / F-1 reproductions. Probably taking notice of Aurora's AFX G-Plus design of 1976, TYCO finally introduced it's first integrated in-line motor chassis design in 1981, the 440 Magnum chassis. This low-profile chassis outperformed anything tyco had ever made due to low mass, high power, & good traction magnetics. The resulting Indy/F-1 bodies it allowed looked quite good if not perfect. This chassis cost more to make than the standard CHHP2 chassis, so it was sold at a premium in addition the the CHHP2 rather than replacing it. This marked the beginning of the high performance/high cost and lower performance/lower cost chassis choice era at TYCO.
