If this is your first "computer" radio, rest assured that it is designed to make initial setup and field-tuning of your airplane easier and more accurate than would be if using a "non-computer" radio. Although this is a beginner or sport system with the requirements of those flyers in mind, in order to make the best use of your Futaba 6EXA and to operate it safely, you must carefully read all of the instructions. Suggestion: If, while reading the instructions, you are unclear of some of the procedures or functions and become "stuck, " continue to read on anyway. [. . . ] (Pressing the MODE key will take you to the next function which is End Point Adjustments). The same as dual rates, "expos" can be set for both switch positions. The exponential "curve" may be set anywhere between -100% and +100%. Enter the programming mode, then select the channel (1-aileron, 2-elevator) you wish to set by pressing the SELECT key. The active channel number will be displayed on the screen with a + or a - next to the number (initially, the value will read ­ 0) 2. Position the dual rate switch where desired for the value you wish to change. (As stated above, an exponential value with a "-" in front of it makes the initial servo movement less, or "softer. ") 4. Flip the switch to the other position to enter the exponential value for that switch position. Repeat for the settings on the other channel. E. P. A End Point Adjustment Note: Since changing the "end points" will also change the dual rates, the end points should be set prior to setting the dual rates. If you set the dual rates first, and then go back and change the end points, the dual rate throws will also change. function is designed to "fine tune" the servo throws in cases where changing the pushrod hookup will not achieve the correct throw. The pushrods should first be connected to the servo arms and control horns so the correct, or near correct control surface throw will be achieved. THEN the E. P. A. s may be used to make small changes in the servo throw until the desired control throw is achieved. The control throws should be set up so that the "end points" are as near to 100% as possible. values must be set below 70% or above 120% to get the desired throw, you should strongly consider changing the pushrod connections so the values can be set closer to 100%. is set to 100% the maximum servo throw for channels 1, 2, 3 & 4 is approximately 40° and approximately 55° for channels 5 & 6. ) To set the end points: 1. Enter the programming mode and use the MODE key to access the E. P. A screen. The channel number being adjusted will appear on the screen and the % symbol will be flashing. To change the RIGHT aileron throw move the aileron stick to the right, then push the DATA INPUT lever up or down to change the value and the throw. Move the stick to the left and use the DATA INPUT lever to change the LEFT aileron throw. Use the SELECT key to display the other channels and set the other end points. Notice that moving the stick (or switch or dial) from one end to the other changes the value displayed and the position of the arrow for that "end" of the control input. [. . . ] A range check is the final opportunity to reveal any radio malfunctions, and to be certain the system has adequate operational range. Have an assistant stand by the model and signal what the controls are doing to confirm that they operate correctly. You should be able to walk approximately 20 - 30 paces from the model without losing control or seeing "jitter" in the servos. Set the transmitter in a safe, yet accessible location so it will be within reach after starting the engine. [. . . ]
