RE: Is it possible for a defective servo to cause a receiver to go defective?
Forgive if this is redundant for you.
With the 9C you can activate the AILEVATOR function and it automatically mixes channel 8 with channel 2 with one reversed from the other. You must, however, activate it, i.e., change INH to ACT. Then make sure the airlon mixing is set to 0%.
