nice to meet you.
traxxas x-maxx 8s jump and drive at high speed
The new servo made in China is dead.
So I made a big decision and proceeded to replace the large servo.
Ha... it was too hard work. ??
I worked on it after 3 days and it was my first time, so I referenced several YouTube videos.
However, there was no easy way.
How to make the parts to fix the servo separately, or how to coat it with a glue gun....
I squeezed my head and worked in a way that was easy to replace later and had good fixation.
Of course, you have to do a test drive to see if it's okay.
First, this is a video of a large servo operation.
