INJORA Coreless High Torque Micro Servo with Mount and Servo Horn for TRX4M TRX4MT 1/18 RC Crawler Upgrade Parts(Black)

Works amazingly!!! Super easy plug and play replacement for the steering servo. You may need to adjust end points but the Quality of the servo speaks for itself. I had to take a Dremel to the servo mount to allow room for the horn's screw (nothing bad less than a MM). this shouldn't be an issue for others as I am going for a very lifted truck. This means the servo needs to be leaning towards the front bumper as much as possible, this limits the space between the attached servo horn screw and servo mount.

Servo looks great, black with aluminum cuts. Fit perfectly with the Injora aluminum axles. Much better performance than stock servo in speed, power, and durability, and price. This set comes with the servo, mount, and servo arm, for the price of the OEM servo alone. Semi easy to install (there are no instructions) If you are using the Injora aluminum axels you will need the 2 micro grub screws and a .05 allen key to install, but set servo into the mount first then tighten the grub screws, but not too tight. Not sure how it fit stock plastic axels.

Very responsive, good control, and strong. Handles the added weight without a problem.

This servo is amazing! Fast and strong servo, great fit and great customer service!

This servo has very good performance. I have it in two custom builds and it has been excellent so far.

I use these exclusively on my custom builds both the lay down and upright super smooth and good speed and torque

Lots of power. Very responsive. Looks great too.

Works well with larger tires and weighted wheels. The servo isn’t designed for the TRX4m necessarily because 1 it’s a little tall. 2 the wiring comes out the front when it should come out the rear. The wiring blocks the screw and caused a cross threaded screw since the wiring is completely in the way. A ball hex will be required to access easily. It’s had an issue with the servo horn screw to the steering link keeps backing out even with threadlock and the thread isn’t stripped. If you work the steering back and forth it will loosen but if you tighten all the way it seems to bind the steering up so something seems to be designed wrong. I didn’t have this issue on my old stock servo even when I had aftermarket brass steering link on that one.
