Installing the PowerSafe Main Unit
1. Using foam or thick double-sided foam tape and tie wraps, secure the
main PowerSafe unit in the position where you would normally mount the
receiver.
2. Mount the switch on the side of your aircraft and insert the switch plug in the
port in the main unit marked SWITCH.
The PowerSafe uses a specifically designed switch. Conventionally wired switches
are not compatible with the PowerSafe.
Installing Optional XPlus8 Module
When using an XPlus
™
receiver and module it is recommended the XPlus8 module
be mounted as close to the receiver as possible. When using the XPlus power
jumper lead mounting the XPlus8 module close will minimize the current loss from
the receiver. Servo extensions can be use with each servo, it is recommended to
use heavy 22 gauge wire with gold plated connectors.
If an auxiliary battery or batteries are to be used there is no need for the XPlus
power jumper. The XPlus8 module can be mounted as far away from the receiver
when using the auxiliary power option.

Battery Voltage
IMPORTANT: D0 NOT use a 4-cell 4.8-volt battery to power the PowerSafe.
Four-cell 4.8-volt batteries do not provide enough voltage headroom (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. Five-cell 6-volt NiMH packs have become the standard for many giant-scale
applications.
Be aware that NiMH batteries have a tendency to false peak when being fast char-
ged. Be especially careful 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, and are easier to manage when charging.
Before using LiPo batteries, please check the voltage specifications of your servos.
Use of a voltage regulator, such as the Spektrum VR6007 (SPMVR6007), might be
necessary.
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.
Installation
The PowerSafe requires a minimum of three remote receivers to operate, and
one receiver must be plugged into the A receiver port. Four remote receivers
are included and, in most cases, it is recommended that three or four receivers
be used. Each receiver functions independently and additional receivers (up to
four) offer a more secure RF link in difficult environments. The added security of
redundancy should a failure occur will outweigh the slight additional penalties of
cost and weight.
