Features
Spektrum’s AR9100 PowerSafe™offers the ultimate solution for
powering high current draw radio systems. In aircraft with multiple
high current draw servos (i.e. giant scale aircraft, jets, etc.), the 9100
PowerSafe can provide peak current of up to 50 amps and offers true
dual battery redundancy and a “fail-on” soft switch for the ultimate in
reliability.
• True dual battery redundancy - each battery is isolated and if one
fails/shorts the other takes over.
• Utilizes up to 4 remote receivers for the ultimate RF link in even the
most demanding applications.
• Up to 35 amps continuous and 50 amps peak current handling
capability
• Soft switch fails-on if the switch is damaged
• Two types of failsafe - Smartsafe (throttle only) and conventional
failsafe (all servos)
• Instant-on reconnect - if a power interruption (brown out) occurs the
system reconnects in less than 1/2 second
• Flight Log compatible
• Heavy 16awg dual battery leads with pre-wired E-flite®EC3
connectors
• Compatible with all Spektrum and JR®full range radio systems

Important
The PowerSafe main unit is not a receiver. The PowerSafe’s main unit is a power distribution center that provides up to 35 amps continuous and 50
amps peak current to power your system. Through extensive testing our engineers discovered that mounting the receiver in the typical location at the
end of the servo and battery leads is not the optimum location to provide the clearest RF signal. The AR9100 PowerSafe uses up to 4 (a minimum of
2 are required) remotely mounted receivers that can be optimally placed in your aircraft providing the best possible RF link in the most demanding
conditions.

Battery Requirements
Using One Battery
The PowerSafe allows the option of using one or two battery packs.
When using one battery simply plug the battery into either one of
the two battery connectors (BATT 1 or BATT2). Be sure to secure the
unused battery connector. Note that the open contacts of the unused
battery are not back powered (not electrically hot), however, the
unused connector should be secured to prevent it from entangling
during flight. When the system is powered using one battery a single
blue LED will constantly emit when the system is powered.
Using Two Batteries
The PowerSafe offers a true redundant dual battery system. When
using two packs, if one should fail (open circuit, short circuit or
becomes fully discharged), the other battery will provide power
to the system. When using dual batteries it’s recommended that
both batteries be of the same capacity and ideally of the same age/
previous profile. When using two batteries the total available capacity
equals the sum total of both batteries i.e. BATT1- 2000mAh +
BATT2- 2000mAh= a total capacity of 4000mAh
Spektrum AR9100 6
It’s important to select a battery(s) that has more than adequate
capacity to provide the necessary flight time. Our staff has been
recording in-flight data to determine typical current consumption of
aircraft in flight. Following are two graphs that illustrate the in-flight
current draw of the radio system.
Airplane - 40% YAK
Servos - 9-JR8711’s 1-8317 (throttle)
Batteries - Two 4000mAh 2-cell 7.4-volt LiPo’s
Regulator - none
Engine - DA150
Weight - 40 lbs
Flight envelope - Hard 3D
Average current - 2.62 amps
Peak current - 17.8 amps
Milliamps used per 10 minute flight - 435mAh
In the example on the right, the average current was 2.62 amps,
which calculates to 435mAh per 10 minutes (typical flight length). It’s
recommended that only 60% of the available capacity be used to ensure
plenty of reserve battery capacity. In this example using two 4000mAh
batteries (8000mAh total capacity) x 60%= 4800mAh (available useable
capacity) divided by the capacity used per 10 minute flight, 435mAh would
allow up 11 flights, of 10 minutes each.

Scale aircraft - The varity of scale aircraft and the accessories they use vary
tremendously making it difficult to give capacity recommendations for these
types of aircraft. Using the above aerobatic guidelines relative to the size
and number of servos used will provide a conservative capacity for your
scale aircraft. As always, check battery charge condition before each flight.

Battery Voltage
IMPORTANT: DO not use a 4-cell 4.8-volt battery to power
the PowerSafe.
Four-cell 4.8-volt batteries do not provide enough voltage head room
(additional margin needed) necessary to power the system when
heavily loaded. Under load the system voltage can drop below the
voltage system’s minimum operating voltage threshold (3.5 volts) and
cause loss of control.
The PowerSafe is capable of handling voltages from 6.0 to 10.0 volts.
The voltage limitations are generally the servos. Most servos are
compatible with 5-cell 6-volt packs, however, and 5-cell 6-volt NiMH
packs have become the standard for many giant-scale applications.
Be aware that NiMH batteries have tendencies to false
peak when being fast charged. Be especially careful and sure
that the when using NiMH batteries that they are fully charged and
have not false peaked.
Many pilots are using 2-cell LiPo batteries to power their aircraft.
LiPo’s offer greater capacity for their size and weight, plus are easier
to manage charging (no false peaks and no self-discharge issues
depending on servo capability and warranty).
Note: When a battery is connected to the PowerSafe a low current
drain of less than 1mA occurs even when the switch is turned off.
If the system is going to be stored for any length of time, it’s
important that the battery(s) be disconnected from the PowerSafe to
prevent over-discharge.
Spektrum AR91009
• Mount the main PowerSafe unit in the position that you would normally
mount the receiver.
• Mount the switch on the side of your aircraft and insert the switch plug
into the port in the main unit marked SWITCH.
Note: The PowerSafe uses a specifically designed switch.
Conventionally wired switches are not compatible with the PowerSafe.
• Using the above guidelines select the battery system that best fits your
application and install the batteries in your aircraft. Connect the battery
to the PowerSafe. Spektrum batteries are pre-wired with an E-flite EC3
connector and plug directly in. If using another brand of battery, it will
be necessary to solder EC3 connectors to the included battery leads.
• Using double sided foam tape and tie wraps, mount a minimum of 2 and
up to 4 remote receivers in your aircraft and plug them into the receiver
ports.
Note: It’s important that one receiver be plugged into port A and a second
receiver be plugged into any other port in order to operate.
• Plug the servo leads into the appropriate ports in the PowerSafe
• You are now ready to bind the system
• Turn on the system. A blue light on the main unit and an amber light on
the remote receiver should turn on indicating the system is powered.
Check servo operation.
Installation
Spektrum AR9100 10
It’s necessary to bind the PowerSafe to the transmitter so that the
PowerSafe will only recognize that specific transmitter and ignore signals
from other sources. If the PowerSafe is not bound to the transmitter, the
system will not operate. During binding the servo’s failsafe positions are
stored.
How To Bind the PowerSafe
1. With the system hooked up and all remote receivers attached as
described previously, insert the bind plug in the DATA/BIND port in
the PowerSafe.
2. Turn on the soft switch. Note that the LED’s on all receivers should be
flashing indicating that the receiver is ready to bind.
3. Establish the desired failsafe stick positions, normally low throttle
and flight controls neutral.
4. Press and hold the bind button on the back of the transmitter while
turning on the power switch. The bind button should flash and within
a few seconds the system should connect. The LED’s on all receivers
should go solid, indicating the system has connected.
5. Remove the bind plug and store it in a convenient place.
6. After you’ve programmed your model, it’s important to rebind the
system so the true low throttle and neutral control surface positions
are programmed.
