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.
