For model racers and weekend builders using brushed motors, the VG Booster and VG Capacitor make a useful electrical tidy-up. Tamiya designed these to tackle voltage fluctuation and motor-generated noise that can upset drivability.
The capacitor is fitted at the ESC to smooth transient voltage changes during acceleration. That smoothing helps the ESC deliver steady power and can reduce random cutouts or surges during heavy throttle use.
Fixed to the motor, the VG Booster reduces electrical interference coming from the commutator area. This cleaner signal path assists in maintaining reliable motor performance and consistent control inputs.
These Tamiya accessories are a sensible electrical upgrade for brushed systems, helping preserve consistent power delivery and reducing noise for a smoother driving experience.
