of the wires before disconnecting the plug from the Tx. Install the NiCd or NiMH

battery by  rst inserting its connector into the jack in the battery compartment.

Battery voltage is shown on the LCD’s home screen for easy monitoring. A “LOW

BATTERY” warning will show when battery power drops to the voltage value shown in

the BATTERY ALARM screen as described on page 12.

WARNING! Never operate an R/C model with weak Tx batteries! Reduced

operational range and/or possible loss of control of the aircraft could

result. Never mix used and new alkaline batteries. Replace weak alkaline

batteries, or re-charge NiCd or NiMH batteries before attempting a  ight!

A “Tx Batt.” timer in the TIMER menu described on page 28 can track the total amount

of time the transmitter has been operational.

See the ACCESSORIES section on page 44 for optional batteries and chargers available

at local hobby retailers.

CHARGE JACK AND CHARGING

RECHARGEABLE BATTERIES

The charge jack should only be used for recharging optional NiCd or NiMH

batteries (charger not included). Do not try to recharge alkaline batteries.

Charge adapter leads for Futaba

brand transmitters are compatible, with

the center pin being positive polarity. The Tx power switch must be in the

OFF position to recharge batteries. Do not charge batteries at greater than

1 amp. Cycling of the Tx batteries can be accomplished through this jack. Misuse,

improper charging, or over-charging of rechargeable cells can result in damage to the

cells that could include cell rupture, explosion, or  re!!

WARNING! Do not accidentally short circuit the terminals inside the charge

jack, as this can cause permanent damage to the radio’s charge circuitry

and battery and void the warranty.

POWER LED

The blue LED illuminates when the power switch is turned on and ample voltage is

supplied by the battery. This LED will  ash if battery voltage drops to the voltage set in

the BATTERY ALARM setting described on page 12.

Channels 1– 6 are fully proportional. Channels 5 and 6 can be controlled by a

non-proportional switch, dial, or slide lever, or mixed to channels 1– 4 for full

proportional control.

Aircraft control is accomplished through various electro-mechanical devices which are

manipulated by the pilot, such as the control sticks, toggle switches, dial, or slide levers.

In addition, the Tx can automatically manipulate the pilot’s control inputs electronically

to alter the control signals before they are delivered to the receiver (e.g. mixing two
