INJORA Purple Viper 1721 Brushless Motor for 1/18 TRX4M Ascent-18

Compatibility:

• ESC: Compatible with INJORA MBL32 ESC, OR30 ESC and QuicRun Mini24 ESC. Not compatible with other ESCs!
• Transmission: Compatible with 1/18 TRX4M, 1/18 Redcat Ascent18 transmissions, not compatible with 370 transmission.
• Battery: 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 Purple Viper is best for rigs under 700g. For heavier rigs, we recommend the 2204 Fat Viper for stronger drag brake performance.

Features:

• Smooth and linear at low speeds, powerful and aggressive at high speeds.
• Runs more quietly than brushed systems, producing virtually no noise.
  
• Includes a protective sleeve at the wire outlet for enhanced durability.
