Because the servos are closed systems they don't have a
hard requirement that their motors run at the same speed,
however it would affect the slew rate which is spec'd so
they have to be reasonably close. If you zapped the capacitor
and turned it into a resistor you would know (it gets hot)
but it is also easy to replace. Use a 100v ceramic caps
since the flyback spark can have a high voltage.
