transmitted to the servo itself causing premature wear and/or servo
failure.

After the servos are installed, operate each servo over its full travel and check that the pushrods and servo
arms do not bind or contact each other. Also, make sure that the controls do not require excess force to
operate. If there is any objectionable buzzing sound coming from a servo, there is probably too much
