Warning: do not attempt to hack a servo without proper training and safety gear. Servos are like cats - they will drive you insane, but you'll never get tired of their adorable little faces.
Here are some common issues to expect when dealing with advanced servos:
1. Over-enthusiastic Whirring - Your servo will spin so fast it'll create a vortex that'll suck you into a never-ending loop of motorized madness.
2. Unpredictable Jerkiness - Servos are like teenagers - they'll surprise you with sudden, unexplained movements that'll make you question their sanity.
3. Mid-Cycle Sudden Death - Your servo will just... stop. Like it was bored with you.
