The Yokomo YT-301A cross wrench is made to streamline assembly and routine maintenance on a wide range of RC chassis. It combines four common hex sizes 7.0mm, 5.5mm, 5.0mm and 4.0mm into one compact tool that fits easily in a pit box or toolbox.
This wrench suits hobbyists working on models such as GT5-R35, GT5-SC430, GT3-REA, GT3-IS350, GT3-B4, GT3-CAX, GT3-BRZ, GT3-AHP, GT-B, GT5-R2, and GT5-RS2, covering several standard fastener sizes used across these platforms.
The cross form gives good leverage while remaining lightweight for trackside tweaks. Carrying multiple hex options in one tool reduces clutter and speeds up set up and repairs during events.
