Bad servo cause damage?
The servos run off the +5v voltage regulator. You can short circuit the voltage regulator and it will just limit the current and work fine when the fault is cleared. Shorting the voltage regulator would drop the gate voltage on the motor switching FETs and turn them off, stopping the motors.
The servos have +5 volts on the center pin (of three) and you can plug the servo connector in backwards with no damage, the servo just won't work. Someone a while back was using a jumper wire to short the servo connector and all it did was reset the DH9116 receiver.
Sounds unlikely that a bad servo could cause damage to anything else.
What will kill the circuit board is stalling a motor. Kill the throttle before you crash. Stalled motors will suck up all the amperes that the LiPo or Li-Ion battery can provide and with a good battery, something has to burn out. It can happen faster than the Motor Overload Protection System (MOPS) can act.
DH9116 printed circuit boards are quite rugged and take much abuse.
