The 7100 reciever requires servo's that will take 8v.I am using the 9 channel reciever with mine and a 2+1 that regulates the volts to 5.8 volts on all my helis.

"The 7100 reciever requires servo's that will take 8v."

I am unable to verify that information.
It is not on any Horizon site I can find.
Can you furnish a source?

Regulated 5.2-voltage output to the Rudder, Gear, Aux 2 and
Throttle channels allowing the cyclic servos to be powered at
high voltage for increased performance while the gyro and throttle
servos are powered by the necessary compatible lower voltage
(5.2V).
The cyclics get whatever voltage you put to them. Just dont use a 4cell nicd.
Because of the built-in regulator the AR7100/AR7100R has a
minimum recommended operational battery voltage of 5.5 volts and
is designed to use 6-volt 5-cell NiMH, 7.2-volts 6-cell NiMH or
7.4-volt 2-cell LiPo batteries. (Higher voltage should be used only if
the servos are compatible.) While the AR7100 will continue to operate
down to 3.5 volts, the AR7100/ AR7100R features a built-in 5.2-volt
regulator for the Rudder, Aux 2, Gear 2, Throttle 2 channels output. A
4-cell 4.8-volt battery will not provide sufficient headroom (voltage
margin) to maintain a 5.2 regulated voltage. Regulated outputs are
provided to allow the gyro, gyro gain and throttle to be operated at the
necessary lower voltage while the cyclic servos (aileron, elevator and
pitch) are powered directly by the pack voltage (typically 5-cell 6-volt
NiMH or if high voltage compatible servos are used 2-cell 7.4-volt
LiPo batteries)
