Motors probably (electric motors aren't too fussy about
voltage), if the speed control is electronic it might handle
it OK. You might want to add some heat sink area (some
aluminum fins to shed more heat from the power-handling
transistors). The most likely point of failure is how it
derives the voltage to feed the electronics - the extra
voltage might cause problems there. (If you feel lucky, try
it and watch carefully for overheating and/or erratic
behavior.)

If the electronics is driven from a separate supply, it
should work fine. Or if you can isolate the electronics,
you could put four silicon diodes in series with the 9.6V
to reduce it to about 7.2V (1N4001's from Radio
Shack or someplace like that would do). -Wm

Most likely can be used in 9.6V batt.  I once use electronic speed control
in a 12V lead acid battery, worked fine.  Electronic speed control concern
mainly on current.  Do not add diode, it will reduce the power output,
approximately 0.7V multiply by the current.  In 10A current, each diode
consume 7W.  Will eventually over heat the diode.

Instead, you need to concern the voltage supplied to the receiver and the
servo.  Reduce the voltage to 6V.  You can use 7806 regulator.

If I ran this r/c, I will use 9.6V for the receiver and server.  I believe
will work find at 9.6V too.
