Graphite main for Tamiya F104

This 3Racing F104-13/WO graphite main is a direct-fit hop-up designed for the Tamiya F104 chassis family. As a dedicated main plate component it replaces the standard main, using the same mounting points to alter chassis stiffness characteristics without changing the chassis layout.

Constructed from graphite, the part focuses on structural rigidity and predictable flex. In practice, swapping the stock main for a graphite unit changes how the chassis transmits load between front and rear, which can be used deliberately when dialing in understeer/oversteer balance on carpet or asphalt tracks.

Installation is straightforward for anyone familiar with the F104 platform: remove the original main plate, fit the graphite unit into the existing mounts and verify clearances for servo leads and other nearby components. Check screw tightness and vehicle geometry after fitting to confirm intended handling changes.

Tuning notes: use the graphite main as one element among springs, anti-roll bars and ride height adjustments. Its effect is primarily on mid-corner stability and transient response, so evaluate changes incrementally and test on your preferred track surface.
