Tamiya 49378 - TRF415MSX Competition Conversion Explained

The Tamiya 49378 - TRF415MSX Hop-Up Conversion Kit adapts the TRF415MS chassis for more consistent lap performance and easier setup adjustments. The package concentrates on predictable handling and a stronger suspension interface for track use.

Balance-Focused Chassis Changes

This conversion reworks the TRF415MS to achieve a lower centre of gravity and quicker access for repairs. Bulkheads are easier to remove for fast drivetrain checks. The extended rear bulkhead shifts mass toward the centre and the shortened upper deck passes between the drive belt to join front and rear bulkheads for improved equilibrium.

Improved Durability and Easier Servicing

Eliminating the middle deck allows the upper arm to bolt straight to the bulkhead, boosting suspension toughness and cutting down on flex during sideways loads. The structure is designed to stay true under aggressive driving. The supplied box also functions as a battery container and can hold up to 11 6-cell battery packs for organised storage.
