Thank you for purchasing the Aero Cruiser/Speed Pilot 12V Field Charger. Using
this charger will give you less down time between flights. Please read all
instructions and warnings before using this charger.
Charging The NiMh Battery Pack
❏ 1. Plug the battery charger into a 12 volt
socket in a vehicle. The charger is
equipped with a 72" charging lead, allowing
the battery to be charged outside of the
vehicle. It is recommended that battery
charging be conducted outside of the
vehicle. Never operate the charger with
the vehicle engine running.
❏ 2. Remove the discharged battery
pack from the plane. Plug the battery
pack into the charger connector. The
battery pack will plug in only one way.
❏ 3. Rotate the timer knob on the
charger to 30 minutes. Make sure the
red light comes on.

❏ 4. IMPORTANT! NEVER LEAVE A CHARGING BATTERY UNATTENDED.
❏ 5. During charging, feel the battery to see if it is starting to warm up. A warmed
up (but not hot) battery pack is a sign that it is fully charged. Once the pack is
warm, disconnect it from the charger. Depending on how much charge was
already in the pack, you may have to disconnect the battery early.
❏ 6. Always disconnect the charger from the 12 volt socket in your vehicle when
finished charging.
❏ 7. After each flight, remove the battery pack from the airplane and allow it to
cool completely before recharging.
Safety Precautions for Charging Batteries
❏ 1. Never leave a charging battery unattended.
❏ 2 Never let the battery charge until it feels hot. A hot battery is an overcharged
battery. Only let the battery get warm to the touch.
❏ 3. If your battery is not completely discharged before charging, the charging
time may take less than 30 minutes. Again, only let the battery get warm to the
touch – not hot.
❏ 4. Never operate the charger with the vehicle engine running. Charging the
battery while your vehicle's engine is running increases the chance of
overcharging the battery.
❏ 5. If you ever use a different battery charger, charge this battery pack only at
a maximum charge rate of 1/2 amp. A higher charge rate will charge the battery
pack too quickly and heat up the wires.
❏ 6. A properly cared for battery pack will last a long time. If the battery pack is
continually overcharged or charged at too high of a rate, the life of the battery pack
will be shortened.
CHARGING THE BATTERY – WARNING!
Be careful to avoid overcharging the battery! When you plug the battery into the
charger there is no way to know how much charge is left in the battery (unless
you have just completed a flight in which the battery was run all the way down).
If you put too much charge into a battery, it will get very hot. This may result in
melting the plastic battery cover, damage to vehicle and could even cause the
battery to explode.
