Battery Charging
The transmitter and receiver battery packs should be charged for at least 16 hours
each evening before flying the next day. The first charge should last between 20
and 24 hours.
Please note:
the polarity of the JR charger is negative centre. This may be
different to other manufacturers' chargers. You must make sure that the centre
pin of your JR transmitter is always connected to negative to ensure correct
polarity.
Charger
The charger supplied with your transmitter features two LED lights. These should
always be lit when a battery is connected. If they are not lit make sure both the Tx
and the Rx are turned off.
During charging the charger will rise in temperature. This is completely normal and
should not be a concern.
If you have any worries or concerns about any of the charging equipment please
seek expert advice.
Please ensure the correct charge rate for your battery pack. Any battery over
1000mah should receive a charger rate of 120ma.
Control Stick Length
The stick units of JR radio equipment feature adjustable stick lengths. Please use
the supplied allen key to make adjustments. Loosen the grub screw by turning the
allen key counter clockwise. Then adjust the stick length to your required length.
Lock the stick in place by turning the grub screw clockwise.
Optional coloured sticks are available from your JR/MacGregor dealer, as well as
long or short sticks.
Control Stick Tension Adjustment
Remove the RF module, NiCad battery and the back cover screws. Remove the
transmitter back, being careful not to bend or damage the RF pins. The tension
screws protrude from the back of the stick assemblies, immediately adjacent to the
tension springs. Adjust each screw for the desired tension (anti-clockwise to loosen
the stick feel, clockwise to tighten the feel).
