About the Top-Force and the Top-Force Evolution 1/10 R/C buggy[]

Released on November 26, 1991, the Top-Force is a four-wheel-drive R/C buggy made by Tamiya. It is the high-end model to the Manta Ray.

Although most aspects of the chassis are the same as the Manta Ray, the main differences is that the FRP double deck chassis frame, the FRP shock towers, adjustable turnbuckle upper arms, universal driveshafts and limited-slip ball differentials, were now standard for the Top-Force. While the Top-Force is heavier than the Manta Ray due to the use of alloy parts for its FRP chassis frame, it was countered by the car's low ride height. It comes with the standard, Mabuchi-made RS-540SH 540-size motor.

The high-end variant to the regular Top-Force, the Top-Force Evolution, was released on June 16, 1992. Unlike the regular model, it was equipped with the carbon fiber double deck chassis frame and shock towers. The optional torque slipper, aluminum dampers, differential housings and full ball bearings were standard for the Evolution model. In additions, all screws were made of lightweight and strong titanium alloy. For some reason, it didn't comes with a 540-size motor as the regular Top-Force does.

Both models were equipped with the spire spike tires and 5-spoke star-dish wheels.

The regular Top-Force has been re-released twice. The 2005 re-release (released alongside the re-release of Manta Ray) had no modification compare to the original, while the 2017 re-release has the spire spike tires replaced by the square spike tires. The Top-Force Evolution would be later re-released in 2021, now with the updated damper and spring units and metallic decals in addition to the square spike tires that were carried from the Top-Force.
