Note: The 1721 Gold Viper is best for rigs under 700g. For heavier rigs, we recommend the 2204 Fat Viper for stronger drag brake performance.
Note: Some noise at mid-throttle is normal for the 1721 motor due to its high-speed, open-rotor design. This does not indicate a defect.
3S batteries are highly recommended for optimal performance and smoother low-speed control.
Reduces mid-range noise with slightly improved torque output.Delivers smooth and linear control at low speeds, with powerful and aggressive performance at high speeds.
New gold finish for a more eye-catching appearance,includes a protective sleeve at the wire outlet for enhanced durability.
