Li-Po Batter y War ning
and Guidelines
If you do not agree with these conditions, return your
complete FREE SPIRIT MICRO/SOLO model in new, unused
condition to the place of purchase immediately.
You must charge the included 3.7V 110mAh LiPo 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 flight, the battery must be cooled to ambient temperature
before charging.
You MUST use the included 3.7V DC LiPo Charger ONLY.
Failure to do so may result in a fire causing personal injury
and/or property damage. DO NOT use a NiCd or NiMH
charger.

Operation Method
Please note this checklist is not intended to be a replacement for
the content included in this instruction manual. Althought it can be
used as a quick start guide, we strongly suggest reading through
this manual completely before proceeding.
Always turn the transmitter on first
Plug the flight battery into the lead from the 5-in-1 control unit
Allow the 5-in-1 control unit to initialize and arm properly
Fly the model
Land the model
Unplug the flight battery from the 5-in-1 control unit
Always turn the transmitter off last
LiPo cells should not be discharged to below 3V each under
load. In the case of the 1S LiPo battery used for the FREE
SPIRIT MICRO/SOLO, you will not want to allow the battery to
fall to below 3V during flight.
The FREE SPIRIT MICRO/SOLO's 5-in-1 control 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 5-in-1 unit will reduce power to the motors (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 LiPo battery that results in lost power and
duration when using the battery for subsequent fights, or
failure of the battery entirely. Continued attempts to further
discharge the battery may also result in loss of control while
the motors are running as the voltage of the battery may drop
below the minimum operating voltage of the receiver and other
electronics.

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 30-45 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.
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
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 LiPo flight battery. Discharging the
battery too low can cause damage to the battery resulting in
