Aircraft Storage
1. Keep the aircraft and parts clean and dry and store them in a cool dry place. Recommended storage
temperature (when the tank, ow meter, pumps, and hoses are empty): between -20° and 40° C (-4°
and 104° F).
2. Make sure to keep the small parts properly to avoid loss. Small parts, such as cables and straps, are
dangerous if swallowed. Keep all parts out of reach of children and animals.
3. Remove or empty the tank when not in use to avoid damaging the landing gear.
4. Remove the battery from the aircraft when stored.
Battery Storage
Disconnect the battery from the aircraft and check if there is any buildup in the battery port.
Power off and disconnect the battery from the aircraft or other devices during transportation.
Keep batteries out of the reach of children and animals. Seek professional medical support
immediately if children swallow parts of the battery.
If the battery level is critically low, charge the battery to a power level of 40% to 60%. DO NOT
store a battery with a low power level for an extended period. Otherwise, the performance will
be negatively affected.
DO NOT leave the battery near heat sources such as a furnace or heater. DO NOT leave the
battery inside a vehicle on hot days.
The battery must be stored in a dry environment.
DO NOT place the battery near explosive or hazardous material or near metal objects such as
eyeglasses, watches, jewelry, and hairpins.
DO NOT attempt to transport a battery that is damaged or has more than 30% power.
Discharge the battery to 30% or lower before transportation.
Make sure the battery is placed on a at surface to avoid damage to the battery from sharp
objects.
If storing the battery for more than three months, it is recommended to store the battery in a
battery safety bag in an environment at a temperature range from -20° to 40° C (-4° to 104° F).
DO NOT store the battery for an extended period after fully discharging. Doing so may over-
discharge the battery and cause irreparable damage to the battery cell.
If a battery with a low power level has been stored for an extended period, the battery will be in
deep hibernation mode. Charge to wake the battery.
Disconnect the battery from the aircraft if you intend to store the battery for an extended period.
