Retro two-step speed controller for Hornet and mates

The Tamiya 50253 Mechanical Speed Control Set provides a straightforward mechanical control option for Hornet restorations. The package includes a rotary switch with wiring harness, a 7-watt ceramic resistor, a protective heat shield, required mounting fittings, and clear instructions. It is aimed at Hornet models but also fits popular siblings like Blackfoot, Lunchbox, Midnight Pumpkin, and Monster Beetle for flexible reuse.

What the kit contains

Two-Speed Functionality: Simple forward and reverse speed selection for classic driving feel.
Comprehensive Kit: Delivered with all wiring, resistor, heat shield and fasteners plus user instructions for basic installation.
Wide Compatibility: Primarily for Hornet yet compatible with a number of older Tamiya trucks and buggies.

Can I fit this into a Lunchbox or Blackfoot?

Yes. The 50253 set is compatible with Lunchbox and Blackfoot as well as several other classic Tamiya models, though some minor mounting adjustments may be needed.

Is the resistor easy to cool during running?

The kit includes a heat shield to help manage resistor temperature. Allow airflow where possible and avoid prolonged high load runs to reduce heat buildup.

Are spare parts available for this set?

Common consumables like the resistor and switch can be sourced from hobby suppliers that stock vintage Tamiya spares. Check parts listings for the 50253 set.

Will modern batteries change performance?

Modern high-capacity packs may alter how the mechanical controller behaves. Stick to battery types and voltages similar to the original Hornet recommendations for predictable results.
