The INJORA Gold Viper 1721 Brushless Motor 2800KV has garnered mixed reviews from customers who have used it in various small-scale RC vehicles, including the TRX4M and other models. Many users appreciate the motor's potential for torque and its fits well with certain rigs, particularly when used in combination with gear ratios that favor crawling over speed. Some users noted the motor's aesthetic appeal, indicating that it looks great in their setups. However, several customers reported significant concerns regarding performance. A common issue mentioned is the noise level, with multiple users surprised by how loud the motor is during operation. Cogging—a phenomenon where the motor stutters or hesitates when starting or at low speeds—has been a significant point of contention. It appears that this manifests variably across different models, with some customers experiencing severe stuttering and overheating issues, particularly after only a brief usage period. While some users found success by pairing the motor with specific transmissions, others found that it simply did not operate well, leading them to replace it with brands like Hobbywing. Overall, while the INJORA Gold Viper motor has its strengths, particularly in terms of design and torque for crawling applications, its reliability and Consistency seem to leave much to be desired. **
