Battery Requirements
Important
The AR7100 and AR7100R require that at least one remote receiver
(included) be plugged into port B or R to operate.
Specifications
AR7100/ AR7100R
Voltage input - 6.0 to 10.0 volts/ 5 to 7 cell NiMH or 2-cell LiPo
Minimum receiver operational voltage - 3.5 volts
Minimum regulator operational voltage - 5.5 volts
Output voltage - Rudder, Aux 2, Throttle 2, Gear 2 = 5.2 volts/
all other channels unregulated (for high voltage
compatible servos only)
Max regulated channel current - 2 amp continuous
Resolution - 2048
Dimensions LxWxH - 47.3x40.2x14.2mm/ 1.86x.1.58x .56 in
Weight - 1.1 oz / 32.5 g
Switch - Soft Switch (Switch port can also be used with charge
adaptors (included))
Connector type - EC3
Note: When the battery is connected to the AR71000/AR7100R a low
current drain of less than 1mA occurs even when the soft switch is
turned off. If the system is going to be stored for any length of time
it’s important that the battery be disconnected from the AR7100 to
prevent overdischarge.
Remote Receiver

* LiPo Packs require the use of high voltage cyclic servos.
IMPORTANT: Do not use a 4-cell 4.8-volt battery to power
the AR7100/AR7100R.
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 7-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 head room (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).
