Delta Peak Charger (see Spare parts list) available
from model shops. Do not use any other type of
charger.
Connect the battery to the mains charger
and charge for
60 minutes,
checking
periodically that the battery is not getting
hot.
WARNING!
If the battery becomes hot to the touch (around
40 degrees Centigrade): STOP charging at
once as batteries can explode or cause a fire if
overcharged!
DO NOT CHARGE FOR LONGER THAN 75 MINUTES!
Useful tip
........................... When a new battery is
being charged for the first time, make a note of
the time required for the battery to become warm
to the touch. At this point the battery will be fully
charged. When this occurs, disconnect the battery
and record the charging time. This is the correct
length of time required for battery charging and
should be observed when recharging the battery
from a completely discharged state. Remember, if
the battery gets HOT, stop charging IMMEDIATELY
as overcharging is very DANGEROUS!
Useful tip
........................... Please note that Nimh
batteries require up to 5 or 6 charge and discharge
cycles before reaching peak capacity.
As long as the battery is not damaged by
overcharging and/or overheating, you can expect
to enjoy around 500 flights (complete charge/
discharge cycles) from one rechargeable battery!
Useful tip
........................... Never attempt to charge
a Nimh rechargeable battery that still has charge in
it–always run the helicopter on the ground until the
main rotor speed drops to half normal flight speed. It
will then be ready to charge.
3. NIMH FLIGHT BATTERY SAFETY
Never throw a Nimh rechargeable battery
into a normal refuse bin. Always recycle
Nimh rechargeable batteries as they contain
chemicals dangerous to people, animals and
the environment.
If the battery becomes hot during charging,
disconnect the battery immediately!
Never leave a Nimh rechargeable battery
charging unattended.
Never leave a battery charging on a car seat
or flammable surface in case of fire.
Never attempt to charge a hot Nimh
rechargeable. Wait until it cools.
4. FITTING THE FLIGHT BATTERY
1. Secure the charged battery pack between
the front and the rear battery retainers
ensuring the rubber band is in place. Slide
the battery to the fully forward position and
hold in position by sliding the silicone rubber
sleeves up to the rear battery retainers.
Do not connect just yet.
PREFLIGHT CHECKS
1. '4-IN-1 UNIT' CHECKS
The 2 trimmers on the front of the '4-in-1' unit are
factory adjusted and should need no adjustment.
The status LED is next to the trimmers. The trimmers
perform these functions:
Gyro gain. The left trimmer (GAIN) adjusts
the amount of gyro tail stabilisation from 0 to
100%. The gyro automatically stabilises the
tail against torque changes and gusts. 90%
is usually the best setting.
Mix gain. The right trimmer
(PROPORTIONAL) adjusts throttle/tail mixing
from 0 to 100% and is very uncritical. 90% is
usually the best setting.
WARNING!
This unit contains delicate electronics. If your
model tips over or crashes when flying or if
your Twister motors are physically stalled and
prevented from turning, you must immediately
reduce throttle to avoid damage to the speed
controllers and other components.
Crash damage and motor stall damage is not
covered by warranty.
