INTRODUCTION Thank you for purchasing the Futaba 6J digital proportional R/C airplane/helicopter system. This radio has been designed and manufactured to provide you with many, many years of modeling enjoyment and fun.
This product is to be used for the flying of radio controlled models only. Futaba is not responsible for the results of use of this product by the customer or for any alteration of this product including modification or incorporation into other devices by third parties. (USA only) Please protect the environment by disposing of rechargeable batteries responsibly.
Reversing (servo reversing): ; = & + # installation by allowing the user to electronically set the proper response direction for each servo. Throw: When speaking of a control surface (such as an elevator or aileron), the throw is the distance that the surface moves. Control surface throw is usually measured at the trailing edge (back) of the control surface and is expressed in inches or millimeters.

Descriptions: Note: A: indicates functions that are only found when the T6J is in the ACRO (airplane) mode. H: indicates functions that are only found when the T6J is in the HELI (helicopter) mode. If neither an A: or H: is indicated the function is applicable to both ACRO and HELI modes. Aileron, Elevator and Rudder dual rate switch: use this switch to select between two aileron, elevator and rudder control throw settings. The throws can be set up however you prefer.
Liquid Crystal Display: Commonly referred to as LCD, this is the screen of the transmitter that displays the programming modes, values entered, etc. MODE key: Used to scroll through and display the different functions. SELECT key: Used to display the values for the current function. Throttle cut button: This button activates the throttle cut function and is used to fully close the carburetor and shut off the engine.
RADIO INSTALLATION Follow these guidelines to properly mount the servos, receiver and battery. @ Make certain that the alignment tab on the battery, switch and servo connectors are oriented correctly and {" | ! + !# them in. When unplugging connectors never pull directly on the wires. Instead, pull directly on the plastic connectors. Doing so will prevent any damage to the wires.
@ To prevent the servo lead wires from being broken by vibration during flight, provide a bit of slack so that the wire is not pulling against the servo or connector going to the receiver. In ! ## " ' ! $= Fasten about 5-10cm from the servo outlet so that the lead wire is neat. Margin in the lead wire. IMPORTANT: In order to maximize the performance and enjoyment of the Futaba T6J transmitter, please read this section carefully and completely.
The two antennas should be placed at 90 degrees to each other. The main purpose of the photo demonstrates how the antenna should be placed. @ The receiver contains precision electronic parts. It is the most delicate radio component on-board the model and should be protected from temperature and other extreme conditions. Allow air to circulate around the receiver. One tip is to utilize small foam blocks like standoffs to ensure that there is an air channel around the receiver.

When using the END key, press and release it to scroll through the options. 4) To select a different model memory press the DATA INPUT lever and hold it downward or upward for 0.5 seconds until the desired model number appears. Release the DATA INPUT lever when the next model memory (MODL) appears on the LCD.

ACRO/HELI Model type select function (TYPE)The model type (TYPE) select function is used to determine whether the selected model memory will bring forth the airplane or helicopter programming. If, for example, the airplane (ACRO) is selected, the programming features and functions which are available will be airplane-related. If, however, a helicopter (HELI) is selected, the available features and functions will be directly related to helicopters.
Note: HELI indicates that the T6J will utilize the helicopter programming and functionality. ACRO represents the airplane model type selection. Transmission Mode Selection (MODE)The T6J offers two different mode transmission selections: S-FHSS and FHSS. The R2006GS which accompanies the T6J is compatible with either the S-FHSS or FHSS settings and adjusts automatically to the signals from the transmitter, accordingly. The S-FHSS mode offers fail safe on all channels.
Throttle-Cut Function (TCUT)The Throttle Cut function is intended to be used for shutting off the engine, or disarming the speed control # $! ' # < {; | + ' ## %_ accordingly.

Servo Reversing (REVR)The servo reversing function is used to change the direction that a servo responds to a control input from the transmitter (stick or switch).
Dual Rates/Exponential SettingsDual Rates/Exponential Settings vary slightly between the airplane (ACRO) mode and the helicopter (HELI) mode. As such, the information pertaining to these functions will be separated into ACRO and HELI sections below.

Continue pressing the MODE or END key until the exponentials (EXPO) menu appears on screen.
The T6J transmitter offers dual rates on the aileron, elevator and rudder channels. The dual rates are assignable to switches A, B or IDL on the transmitter and are simultaneously activated by the dual rate switch selected. The amount of travel decrease for each control may be set between 0% and 140% of the values set for the end points (explained in End Point Adjustment on page 33).
