While static and in any flight mode the LED flashes purple light, this indicates the module needs a Gyro Reset.
GuiLin FeiYu Electronic Technology Co., Ltd. http://www.feiyudz.cn E-mail: service@feiyu-tech.com VIBRATION DAMPING a) FY-41AP is vibration-sensitive equipment. To optimize stabilization & autopilot function, vibration reaching the unit must be kept at minimum. b) When installing the module, we highly recommend that you use the supplied vibration absorbing pads as shown below.
GuiLin FeiYu Electronic Technology Co., Ltd. http://www.feiyudz.cn E-mail: service@feiyu-tech.com CHECKING FOR VIBRATION LEVELS Even with the shock absorbing mount, your aircraft set up may not meet the vibration damping requirement. To check for vibration level, please follow this procedure： Installing the entire system as recommended (ensure correct orientation). With the system fully operational, carefully run the plane engine or motor at different throttle levels. DO NOT TAKE OFF.
GuiLin FeiYu Electronic Technology Co., Ltd. http://www.feiyudz.cn E-mail: service@feiyu-tech.com SWITCH CHANNEL SETTING a) FY-41AP needs two 3 way-switches to control its flight modes： SW1 is used to select either manual mode, stabilized mode & 3D mode. SW2 is used to set Auto Return To Launch Mode, Fixed altitude & Heading lock flight Mode & Auto Circling Mode. b) SW2 function had priority over the SW1. Only when SW2 switch to cancel (Null) position can the SW1 switch work.
GuiLin FeiYu Electronic Technology Co., Ltd. http://www.feiyudz.cn E-mail: service@feiyu-tech.com FY-41AP INSTALLATION ORIENTATION a) FY-41AP support 4 installation orientations (LOGO arrow to up, down left or right).
