They have tested and the heat supposedly doesn't cause any issue...
So I'm running them cause the speed and torque is good and they cost too much to not run hah.
Will see how long they last

I have a 9372 that's real super noisy.
When it's pulling on the carb it makes noise without a throttle ret spring and with the spring connected, it's worse. Just plain noisy no matter what I do.
So they told you it's normal?
It's a new servo I paid 149 for but I'm really not wanting to use it. It just doesn't seem safe to me like it's not normal and would cause a runaway.
