Usage Guidelines, Warnings and Safety Precautions

• Always inspect batteries before charging.

• Never charge or use a Li-Po battery or pack that shows any damage or

disfigurement of any kind. Swelling is a sign of internal damage. Any breach

of protective cover, wiring or plugs is also reason to discontinue use. See the

manufacturer’s instructions for proper disposal of Li-Po batteries.

• Never charge near or in the area of any flammable or combustible materials.

• Always charge Li-Po batteries in or on fire-resistant materials or containers.

• Do not store or charge Li-Po batteries with or around other batteries or battery

packs of any type, including other Li-Pos.

• Never leave the battery and charger unattended while in use. Improper charging or

discharging of Li-Po batteries could result in fire.

• Constantly monitor the temperature of the battery pack while charging. If the

battery becomes hot to the touch discontinue charging immediately. Disconnect

the battery from the charger and observe it in a safe place for approximately 15

minutes.

• If at any time you see a battery starting to balloon or swell up, discontinue charging

immediately. Disconnect the battery from the charger and observe it in a safe place

for approximately 15 minutes.

• Do not allow children to charge Li-Po battery packs.

• This charger is designed for 1-cell Lithium-Polymer batteries ONLY. It MUST NOT be

used to charge other size Li-Po batteries, Ni-MH or Ni-Cd battery packs.

• Never attempt to dismantle the charger.

• Always disconnect the charger from the power supply after charging the battery.

• Disposal of Li-Po batteries requires special care. Follow the manufacturer’s

instructions for safe disposal.

Transmitter Preparation

Please make sure you have fresh/charged batteries in your transmitter. If applicable,

set your transmitter model to the correct Airplane. JR

and Spektrum transmitters’

servo settings should be set to default (normal) servo direction. Futaba transmitters

(equipped with Spektrum modules) may require you to reverse the throttle channel.

We highly recommend using a radio that is capable of dual rates and expo. Although

the 4-Site can be flown on any DSM2 radio, it is recommended that you use a radio

with these features due to the quick response and aerobatic nature of the aircraft.

Transmitter Control Identification

Note: Before each flight, you should ALWAYS turn the transmitter on before

connecting the flight battery to the receiver unit. After each flight, be sure

that you always disconnect the flight battery from the receiver unit before

powering the transmitter off.
