Compatibility:

Only compatible with INJORA MBL32 ESC and QuicRun Mini24 ESC. Not compatible with other ESCs

Compatible with stock SCX24 transmission and INJORA metal transmission

For stock SCX24 chassis, the ESC tray must be trimmed to fit the motor

3S batteries are highly recommended for optimal performance and smoother low-speed control

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.

The 1721 Gold Viper is best for rigs under 700g. For heavier rigs, we recommend the 2204 Fat Viper for stronger drag brake performance.

Features:

New gold finish for a more eye-catching appearance

Reduces mid-range noise with slightly improved torque output

Includes a protective sleeve at the wire outlet for enhanced durability

Delivers smooth and linear control at low speeds, with powerful and aggressive performance at high speeds
