5.2 Charging the Ni-Cd batteries
The transmitter and receiver batteries included with you
FS-TH9 X system are rechargeable,Ni-C d batteries.Ni-C d
batteries require special care and charging.
NOTE:The batteries are partially charged,but will require
a full, overnight charge before the model may be flown.
1.Connect the transmitter charging cord coming from the
A/C wall charger to the charge jack in the right side of
the transmitter case. The receiver charging cord may be
connected to the batteries two different ways:The charge
cord may be connected directly to the battery pack, or t o
the vacant charge connector(llack)coming from the on/off
switch in the model.Charging"through the switch"is preferred
as there will be no need disconnect the battery.
2.Plug the A/C wall charger into a wall outlet.Note:If the wall outlet can be turned
off by a switch in the romm, be certain the switch remains on after leaving the room.
Otherwise,the batteries will not be charged!
3.The LEDs(light-emitting diodes)should light red, indicating that current i s flowing
and the batteries are being charged.Discharged batteries will take about 15 hours to
fully charge.If using an aftermarket fast charger,be certain to follow the manufacturer's
instructions provided with the charger so you do not overcharge the batteries.NEVER
charge the batteries at a rate higher than 1000mA.The batteries should also be discharged
periodically to periodically to prevent a condition called"memory".If,for example,
only two flights are mode each time you go flying,the batteries will not have"reached
"very far down into their full capacity.After doing this several times the batteries
will"remember"and eventually"think"they can supply only enougt power for two fights.
After two flights the batteries may not provide enough power to operate the system,
thus causing a crash.To erase any potential memory,cycle the batteries by discharging,
then charging them with a commercial battery cycler,or leave the system on and exercise
the servos by moving the transmitter sticks until the even during the winter or periods
of long storage.If using a cycler with a readout,note the cajpacity after the batteries
have been cycled.If there is a noticeable drop in capacity the batteries should be
replaced.
NOTE :charging your batteries with the included FLYSKY A/C battery charger i s always
safe.However,fast-charging with an aftermarket charger is acceptable as long as you
know how to properly operate the charger,NEVER charge at a rate higher than 1000mA.If
not done correctly,fast-charging can damage the batteries.

5.3Range Testing Your R/C System
Please note that different systems demonstrate different range checks and the same system will
range check differently in different conditions.Also,the receiver antenna's installation affects
the range test--exiting the top of the model is ideal.This is a brief explanation o f range test.
For more in-depth specifics onreceiver antenna mounting,additional checks if unsatisfactroy rage
is demonstrated,range checking with gasoline powered engines,etc,please see our F.A.Q.page a t
www.flyskychina.com.
.Leave the transmitter's antenna retracted and be sure both batteries are fully charged.
.Plsition the aircraft away from wires,other transmitters,etc.
Test one-engine/motor off,minimum of 100 ft.range:
.Have a friend view the model but not hold it,engine off.(People conduct signals,too! )
.Walk away from the model,working all controls constantly.Stop when the servos jitter
significantly(a jitter here and there is normal),control movement stops(PCM),or you lose
control altogether.
.Measure the distance.I f greater t han 1 00 feet,great!Proceed to Te st 2.Less tha n 100 f eet o f
range check means you need m ore information to determine i f your system is sa fe t o fly.Please
see out web sit e or call support for additional tests to perform before fl yin g yo u r system.
.Repeat with friend holding the model.Note any differences.
