User manual FUTABA FX10

[. . . ] Always exit programming mode before attempting to fly the model. Only use the FX10 with a 2. 4GHz system such as the Futaba FASST system, or a PCM system. Use with a FM system is strongly discouraged since interference can cause serious operational problems. Gyro operating precautions: Gyro The FX10 requires 5-10 seconds to initialize when the power is turned on. Do not move the helicopter and do not move the tail rotor stick during this initialization or the gyro may not initialize properly. [. . . ] The servo does not bind when full left or full right tail rotor is applied. The gyro is operating in the correct mode (AVCS or Normal). The tail rotor stick operates the tail rotor the correct direction. The gyro compensates the correct direction when the helicopter is rotated. The gain is set correctly and the gyro operates in the correct mode (AVCS or Normal) in every flight condition. 38 ADJUSTMENTS DURING THE TEST FLIGHT WARNING Always make small (1%) adjustments to the tail Over 100%, it is possible to exceed the sensor's second). The gyro will then no longer control the pirouette rate or consistency. The pirouette rate will be extremely fast. If you experiment with the ultra-fast pirouette rate, make sure that your flight battery and fuel tank are secure. Also be certain that your model's tail rotor drive train is up to the task. The Tail Rotor AFR or D/R function within the transmitter is used to adjust the pirouette rate of the helicopter. For example at 100% D/R, with the gyro set to F3C mode, the helicopter will achieve a 450 deg/sec pirouette rate. If you would like the model to pirouette faster, then increase the AFR or D/R. The use of these functions is strongly encouraged. Shown below is a recommendation of settings: Recommended Gyro Function Settings: Switch: Condition Type: GY or AVCS Gain Values Normal: 70% A (AVCS) Idleup 1: 40% A (AVCS) Idleup 2: 40% A (AVCS) Hold: 70% A (AVCS) 2-Position Switch A Gyro Mode Gain Channel ATV or EPA 100% B AVCS 70% AVCS Side NORMAL 70% Normal Side GAIN % 50% 0% +100% Neutral 0% -100% 42 SETTING THE GAIN If your transmitter does not have a Gyro function built in then it will be necessary to use the ATV or EPA function to control the gain. The Gyro Gain channel will generally be assigned to a switch which provides two gain values. Simply set the ATV or EPA for the gyro channel to the desired gain value and set the Gain Switch to the desired mode of operation. Unfortunately since you will only have one gain value available it will be necessary to use the lowest value needed (for example Idleup 2). When using this method of controlling the gain, one direction of the switch will be AVCS mode and the other direction of the switch will be Normal mode. Always ensure the gyro switch is set to the desired mode before flying. Do not accidentally change the gyro switch in flight. 43 GOVERNOR BASIC SETTING This sets the governor's fundamental functions. The menu (9) Servo limit point setting must be set first. Push MODE +/­ key (1) Start display The editing menus are scrolled by pushing the mode + or ­ key. (2) Revolution setting [range: 1000 rpm] 3000 Setting the main rotor revolution. This is calculated by engine revolution with the gear ratio of the main shaft. · Using by 3position switch Make sure the display is changed to 1, 2, 3 by moving the switch. [. . . ] Pushing data+ or ­ key, the mode is changed. (4) Operation response default: Middle This selects the governor operation response. Select the best match for your engine type. Pushing data+ or ­ key, the mode is changed. [. . . ]
