Congratulations on the purchase of your Ultra-Micro™ 4-Site™. Its amazing
performance is the result of many E-flite advances, not the least of which is a
stamped-foam manufacturing technique that results in wing, fuselage and tail parts
that are actually lighter, stiffer and more durable than standard sheet foam. The airfoil
shape of the wing also provides superior performance to sheet foam. These parts
are further reinforced with carbon rod and foam bracing that minimizes in-flight flexing
and twisting.
This robust construction, combined with the precision of Spektrum™ 2.4GHz DSM2™
technology and long-throw Ultra-Micro servos, gives the 4-Site a level of control and
responsiveness you will instantly fall in love with. But before you get started, take
some time to read this manual. The Ultra-Micro 4-Site is designed for experienced 3D
foamy pilots and as such requires a radio capable of supporting dual rates and expo.
In addition to basic operation and maintenance instructions, you’ll find valuable radio
setup tips that will help make your first flight the best it can be.

Flying Checklist
Please note this checklist is not intended to be a replacement for the content included
in this instruction manual. Although it can be used as a quick start guide, we strongly
suggest reading through this manual and other documentation included with the
product completely before proceeding.
• Always turn the transmitter on rst and set at least 2 feet away from the aircraft
• Plug the ight battery into the receiver and install the ight battery
• Connect the ight battery into the power lead of the AR6400L receiver
• Allow the receiver to initialize and arm properly
While the Celectra 4-port Battery Charger (EFLC1004) included with
your 4-Site has been specifically designed to safely charge the included
1S 3.7V 150mAh 12C Li-Po Battery (EFLB1501S), you MUST read the
following safety instructions and warnings before handling, charging or using
the Li-Po battery.
Note: Li-Po batteries are significantly more volatile than
the alkaline, Ni-Cd or Ni-MH batteries used in RC
applications. All instructions and warnings must be
followed exactly. Mishandling of Li-Po batteries can
result in fire.
By handling, charging or using the included Li-Po battery you assume
all risks associated with lithium batteries. If you do not agree with these
conditions, return your complete 4-Site model in new, unused condition to
the place of purchase immediately.
• You must charge the included 1S 3.7V 150mAh 12C Li-Po battery in a safe area
away from flammable materials.
• Never charge the battery unattended. When charging the battery you should always
remain in constant observation to monitor the charging process and react to
potential problems that may occur.
• After ight, the battery must be cooled to ambient temperature before charging.
• You MUST use the included 4-port Celectra 1S 3.7V Li-Po Battery Charger
(EFLC1004). Failure to do so may result in a fire causing personal injury and/or
property damage. DO NOT use a Ni-Cd or Ni-MH charger.
• If at any time during the charge or discharge process the battery begins to balloon
or swell, discontinue charging or discharging immediately. Quickly and safely
disconnect the battery, then place it in a safe, open area away from flammable
materials to observe it for at least 15 minutes. Continuing to charge or discharge
a battery that has begun to balloon or swell can result in a fire. A battery that
has ballooned or swollen even a small amount must be removed from service
completely.
• Fly the model
• Land the model
• Disconnect the ight battery from the receiver
• Always turn the transmitter off last
• Store the battery at room temperature in a dry area for best results.
• When transporting or temporarily storing the battery, the temperature range should
be from 40–120 degrees Fahrenheit. Do not store the battery or model in a car
or direct sunlight whenever possible. If stored in a hot car, the battery can be
damaged or even catch fire.
• Do not over-discharge the Li-Po ight battery. Discharging the battery too low can
cause damage to the battery resulting in reduced power, duration or failure of the
battery entirely.

Li-Po cells should not be discharged to below 3V each under load. In the case of the
1S Li-Po battery used for the 4-Site, you will not want to allow the battery to fall to
below 3V during flight.
The 4-Site receiver unit features a soft low voltage cutoff (LVC) that occurs when the
battery reaches 3V under load. When the soft cutoff occurs, the ESCs of the receiver
unit will reduce power to the motor (regardless of the power level you have set with
the throttle stick) in order to prevent the voltage of the battery from dropping below
3V. This reduction in power usually requires that you land the model immediately, at
which point you should power down the model and unplug the flight battery. And while
it is possible to power the model up and to fly again after the soft LVC occurs, this
is NOT recommended as continued discharging to the soft LVC will cause permanent
damage to the Li-Po battery that results in lost power and duration when using the
battery for subsequent flights, or failure of the battery entirely. Continued attempts
to further discharge the battery may also result in loss of control while the motor is
running as the voltage of the battery may drop below the minimum operating voltage
of the receiver and other electronics.
Celectra 4-Port 1-Cell 3.7V 0.3A DC Li-Po Charger Instructions
LED functions under normal operation:
• Solid – Charging
• Blinking – Charging nearly complete
• Off – Fully Charged
Replace D-size batteries when:
• LED remains solid for over 60 minutes when charging (70mAh–150mAh) Li-Po
batteries
• LED remains solid after removing single-cell Li-Po batteries from individual ports.
• LED remains off after inserting discharged single-cell Li-Po batteries in individual
ports.
Also, it is not recommended that you fly to the soft LVC every time you fly. Instead,
you should be aware of the power level of the battery/airplane throughout the flight,
and if at any time the airplane begins to require more throttle than typical to maintain
flight, you should land the airplane immediately. Routinely discharging the battery to
the soft LVC can still cause permanent damage to the battery.
If you have any further questions or concerns regarding the handling, charging and/or
use of the included Li-Po battery, please contact the Horizon Support Team
at 877-504-0233.
It is important that you only charge E-flite and ParkZone 1-Cell 3.7V Li-Po batteries,
used in our Ultra-Micro flyers, with the Celectra 4-Port 1-Cell 3.7V 0.3A DC Li-Po
Charger (EFLC1004). Please familiarize yourself thoroughly with the Battery Warnings
and Guidelines section before continuing.
