What Stands Out
High Speed Performance
The INJORA Gold Viper 2800KV motor enhances your TRX4M's speed, offering thrilling performance for enthusiasts seeking a competitive edge in off-road adventures.
Brushless Technology
Featuring advanced brushless technology, this motor delivers consistent power and efficiency, ensuring longer run times and reducing maintenance compared to traditional brushed motors.
Easy Installation
Designed as an upgrade for the TRX4M, it allows for quick and straightforward installation, making it perfect for hobbyists looking to enhance their RC vehicles without extensive modifications.
Product Details
- Note: Compatible with INJORA MBL32 ESC and QuicRun Mini24 ESC. Not compatible with other ESCs, compatible with TRX4M and Ascent-18 transmissions, not compatible with 370 transmission.
- 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.
