A fusion of RDX and VX-DOCK ZERO. The birth of the competition spec M chassis! The M-competition for RDX conversion kit uses the integrated front unit “VX-DOCK ZERO” and a carbon chassis and upper deck compatible with wheelbases of 210mm/225mm/240mm. By combining it with the RDX drive unit, battery holder, and front knuckle (recommended), it delivers driving performance on par with that of a competition model, despite being an M size.
