Hello~~
This is the XMaxx EzRun 4985 1650KV upgrade video.
This video is made for people like me, so please refer to it.
In the case of Big Servo, it has been upgraded with a modification.
The servo force was so strong that the tie rod (plastic) was bent.
Please refer to the method of changing to an aluminum tie rod.
Currently, after changing the big servo, it is in use without any trouble even after numerous jumps and powerful driving.

Motor mount : JH Racing CNC aluminum alloy motor fixing bracket
Tie Rod : NEW ENRON Aluminum 46MM Servo Steering Linkage Tie Rod
