INTRODUCTIONThank you for purchasing the Futaba®6EXA digital proportional R/C aircraft system. If this is your first “computer” radio, restassured that it is designed to make initial setup and field-tuning of your airplane easier and more accurate than would be ifusing a “non-computer” radio. Although this is a beginner or sport system with the requirements of those flyers in mind, in orderto make the best use of your Futaba 6EXA and to operate it safely, you mmust ccarefully rread aall oof tthe iinstructions. Suggestion: If, while reading the instructions, you are unclear of some of the procedures or functions and become “stuck,”continue to read on anyway. Often, the function or procedure will be explained again later in a different way providing anotherperspective from which to understand it. Another suggestion is to connect the battery, switch and servos to the receiver andactually operate the radio on your workbench as you make programming changes. Then, you’ll be able to see the effects ofyour programming inputs. 2Introduction ...................................................................................2Service............................................................................................2Contents aand sspecifications .......................................................3Glossary .........................................................................................3Introduction tto tthe 66EXA ssystem ...............................................4Transmitter ccontrols aand ddescriptions ......................................4Radio iinstallation .........................................................................5Receiver aand sservo cconnections ................................................7Charging tthe NNi-CCd bbatteries ......................................................7LCD aand PProgramming ccontrols.................................................8Programming tthe TT6EXA rradio ..................................................9Model select/Data reset ....................................................10Servo reversing....................................................................10Dual rates.............................................................................10Exponentials.........................................................................11End Point Adjustments.......................................................11Trims......................................................................................12Programmable Mixer..........................................................12Pre programmed “wing” mixing .......................................13Flow chart.............................................................................16Other TT6EXA ffunctions ..............................................................17Trainer switch.......................................................................17Flap control lever.................................................................17Adjustable-length control sticks .......................................18Changing the stick mode...................................................18Flying ssafety gguidelines ............................................................18Flight ppreparation ......................................................................19Frequency CChart .........................................................................20Futaba AAccessories....................................................................20Model DData RRecording SSheets .................................................21TABLE OOF CCONTENTSThis product is to be used for sport and recreational flying of radio-control models only.

GLOSSARYIt will be helpful to understand the following terms before reading the rest of the manual. The terms are not in alphabeticalorder, but are in a logical order that prepares the reader for understanding the next term.Reversing ((servo rreversing) – A function that allows the user to determine the direction of response of each servo. If, afterhooking up the servos, a control on the model responds in the wrong direction, the user may change the servo’s direction sothe control responds correctly. Throw – When speaking of a control surface (such as an elevator or aileron), the throw is thedistance the surface moves. Control surface throw is usually measured at the trailing edge of thesurface and is expressed in inches or millimeters. The model in the diagram has 1/2" [13mm] ofup elevator throw. Throw can also refer to the distance a servo arm (or wheel) travels. Dual rrate ((D/R) – On the 6EXA the dual rate switch allows you to instantly switch, in flight,between two different control throws for the aileron and elevator. Often, different controlthrows are required for different types of flying. (“Low” throws may be required for flying athigh speeds where the model’s response becomes more sensitive, and “high” throws may be required for aggressive aerobaticmaneuvers or landing or flying at lower speeds where the model’s response becomes less sensitive.) End ppoint aadjustment ((E.P.A.) – Sets the overall, maximum distance the servo rotates in either direction. (No matter where thedual rates are set, the servo will never travel beyond the limit set by the end point adjustment.) Exponential – Normally, servos respond proportionally to control stick input from the transmitter (e.g., if the stick is moved halfway,the servo will move halfway). However, with “exponential,” the servo can be made to move more or less than initial stick movement(less servo movement is more common). Exponentials are commonly used to “soften,” or decrease initial servo travel for the aileronsand elevators. This way, initial control stick inputs from the pilot result in small servo movement for a smoother flying airplane. (Dualrates adjust the amount of servo travel. Exponentials determine where most of the travel will occur.)Mixing – Two (or more) servos can be made to operate together either by mechanically joining the wires (with a Y-connector)or by electronically “joining” them through programming functions in the transmitter. When servos are electronically joined viaprogramming, they are said to be “mixed.” Unlike joining servos with a Y-connector, when servos are mixed electronically theycan be made to move in opposition. Additionally, each servo’s end points can be independently set. 3Transmitter:T6EXA Transmitter with programmable mixing and 6-modelmemory.
