For those running the Tamiya TRF419, the RADTEC 2.0mm Aluminium Main Chassis is a practical upgrade to reduce unwanted flex. It is matched to TRF419 mounting points to simplify fitting and setup work.
The increased plate thickness provides a firmer platform for suspension components, sharpening steering response and making small corrections more effective at speed.
Designed to add stiffness without excessive mass, this aluminium option supports finer tuning of roll and pitch behaviour while keeping the model nimble.
