User manual FUTABA FC-16

[. . . ] BEFORE EACH FLIGHT: Always check the transmitter and receiver battery voltage to ensure they have enough remaining capacity to complete the flight. Only use the FC-16 with a 2. 4GHz system such as the Futaba FASSTTM system, or a PCM system. Use with an FM system is strongly discouraged since interference can cause serious operational problems. Gyro operating precautions: Gyro The FC-16 requires 5-10 seconds to initialize when the power is turned on. Do not move the helicopter and do not move the tail rotor, aileron and elevator sticks during this initialization or the gyro may not initialize properly. [. . . ] The FC-16 should compensate by adding clockwise rotation pitch to the tail rotor blades. If the FC-16 compensates by adding counter-clockwise rotation pitch to the tail rotor blades, then it will be necessary to reverse the Compensation Direction setting by pressing the [+] or [-] data key. WARNING Verify that the tail gyro compensates in the correct direction before flight. If the compensation direction is incorrect the model will pirouette uncontrollably, at a very high rate. 36 RUDDER GYRO BASIC SETTING (4) Limit setting [default: 100%, setting range: 50~150%] When the FC-16 is in the Sv. Limit parameter the gyro will no longer operate and the tail servo will always center when the tail rotor stick is released. Before each flight always ensure that the gyros are operating and compensating in the correct direction. The Servo Limit parameter within the FC-16 is used to set the mechanical limits for the tail rotor servo. To obtain the best performance it is recommended to set the limit in the FC-16 the servo arm length to set the mechanical endpoints. After that has been completed use the servo limit parameter to make small adjustments that could not be made mechanically. ´ Sv. Limit menu and slowly move the rudder stick to the left or to the right maximum extent and use the data [+] or [-] key to increase or decrease the maximum throw respectively. Ensure that the pitch slider does not reach the maximum extent and cause binding. WARNING When using the FC-16 for the first time, or when making mechanical changes involving throw, you must check and set the servo limits again to prevent binding. 37 RUDDER GYRO BASIC SETTING (5) Flight mode [default: 3D] Selects the flight mode. Always try the "Sports" flight mode first and if you determine that the feel is not aggressive enough or if the pirouette mode.

(2) Gyro direction [default: Normal] This parameter controls which direction the FC-16 (roll axis) will compensate when the helicopter rolls. Available Flight Mode Presets: 1 - Least aggressive, good for beginners 4 - Fairly aggressive 5 - Extremely aggressive 45 SWASH BASIC SETTING (6) Aileron servo reverse [default: Normal] This setting is used to set the operational direction for the Aileron CCPM servo. The easiest way to set up the FC-16 is to observe which direction each servo needs to move when the collective stick is moved towards positive collective pitch. If the servo is moving the wrong direction then press the data [+] or [-] key to reverse that specific servo within the GY750. Once the collective is operating in the correct direction, check the cyclic controls. If the cyclic controls operate in the wrong direction, reverse FC-16. (7) Elevator servo reverse [default: Normal] This setting is used to set the operational direction for the Elevator CCPM servo. The easiest way to set up the FC-16 is to observe which direction each servo needs to move when the collective stick is moved towards positive collective pitch. If the servo is moving the wrong direction, then press the data [+] or [-] key to reverse that specific servo within the GY750. Once the collective is operating in the correct direction check the cyclic controls. If the cyclic controls operate in the wrong direction, reverse FC-16. 46 SWASH BASIC SETTING (8) Pitch servo reverse [default: Normal] This setting is used to set the operational direction for the Pitch CCPM servo. The easiest way to set up the FC-16 is to observe which direction each servo needs to move when the collective stick is moved towards positive collective pitch. If the servo is moving the wrong direction, then press the data [+] or [-] key to reverse that specific servo within the GY750.
