/ 10

Excellent

Main highlights

•【Compatibility Notes】TRX4M users must use the INJORA custom servo mount for proper installation. Not compatible with INJORA’s TRX4/TRX6 25T Adjustable Servo Arm. SCX10 III users should ensure compatibility with 20T servo splines; this servo uses a 25T spline.
•【Brand Guarantee】 The INJORA 7KG 2065 Digital Micro Servo is ideal as a steering servo for micro crawlers and also works great as a shift servo for 1/10 scale crawlers such as TRX4 and SCX10 III.
•【Waterproof Design】 IP66 waterproof, ideal for wet trail conditions. Note: Not suitable for full submersion.
•【Enhanced Durability】 High-strength stainless steel gears reduce wear and ensure stable performance.
•【Weight Limit & Modification Advice】For heavily modified TRX4/TRX6 models (e.g., with brass parts or oversized tires), consider upgrading to a higher-torque servo to prevent gear damage.
•【Customer Support】 Comes with INJORA's warranty and support. Contact us for assistance or replacements.
