Summary of Contents for MyFlyDream MFD

  • Page 1 MyFlyDream AutoPilot V1.0 www.MyFlyDream.com...
  • Page 2 MFD has build-in 3-axis gyro, 3-axis Acceleration sensor ，3 axis digital compass and barometer. AP has two CPUs, one for the MFD attitude calculation, the other in charge for the OSD and fly logic control. Base on this advance hardware, AP can be used for plane stabilized, way point with altitude fly, and achieve autopilot and auto fly.

  • Page 5 This port will supply the power to the MFD AP. The AP has it own voltage regulator, can be power from 7-20V, but the camera and the video transmitter will also share the power directly from this port. Most of the camera and video TX are 12V, so we recommend you to power the MFD AP with 3S lipo, and will make the connection more pretty and easy.
  • Page 6 The bottoms are grounds they are internal connected also. Power to this port will not power up MFD AP, if the main power port is not connect to the power.

    the G port of the AP to monitor the OSD display to set up the parameters Turn on your controller and make sure the CH5 and CH6 is on the low position. Around 1000us, if the connection is right, when power up you can see the G and R led on the AP flash two times.

  • Page 14: First Time Power Up

    First time power up Please follow the below procedures to setup the AP: 1) radio CH5 and CH6 on the low position, on the OSD display you should see the MAN(manual mode) on the left up corner of the screen. Move the elevator rudder and the aileron you should see the moving correspond to the stick.
  • Page 15 (airplane bank right ，aileron left is up, right is down) (nose up, elevator down)
  • Page 16 （when the airplane spin left, rudder to the right. When spin right, rudder to the left.） if the servo movement is not expected, enter the OSD menu, go to PLANE SETTINGS, set the wrong movement channel to REV. for instance, when nose up, elevator also goes up. You have to change the ELE in the menu to the REV.

  • Page 17: Osd Layout

    see the”QUIT” show on the OS, by using the aileron stick to the left to finish the calibration. In the COMMON CALIBRATIONthe parameters that are calibrated show as below： 1. Aileron elevator and rudder center point of your radio 2. AP installation error, show as degree off the roll and pitch 3.
  • Page 18 OSD display will slightly change base on the fly modes A. Fly time B. Fly modes。Has 6 modes including MAN/STB/WPT/CIR/RTH， about 6 fly mode detail please refer to (8. Test fly) C. heading。Heading to the north is 0 degree. East south and west are 90,180,270.When the airplane’s speed are greater than 20km/h.
  • Page 19 F. Ground speed，unit: km/h。 G. altitude，unit: meter。Data comes from barometer. H. Home direction indicator (when in waypoint navigation mode, indicator will point to the current waypoint direction. When in CIR circle mode, indicator point to the circle point) when the indicator point to the 12 clock direction, it means the home position or way point position or circle point is in front of the airplane.
  • Page 20 L. altitude 。 This number only shows when the AP is in CIR,WPT,RTL modes. Indicate that the AP is trying to reach the setting altitude. When this number change the number type will become larger than regular to cause your tension on this number.
  • Page 21 T. Climbing rate。Fully mark of this bar is 4M/S. if the climbing rate greater than 4, it will show up the number on the side.。 U. Waypoint icon. Only shows in waypoint mode. Simulate the position base on the launch point(home position) ， flashing point with number is the current heading waypoint.in WPT mode, the throttle is controlled by AP.

No level and stabilize Stabilizer， Stabilizer mode, the AP will control the MIDDLE airplane back to level position when you free the control stick. Throttle is control by user.。 WayPoint，waypoint mods, the AP will continue the waypoint one by one preset by user.
  • Page 23 When you nose down the airplane, the elevator will go up, when you nose up the airplane, the elevator will go down. When you level the airplane, the Artificial horizon in the OSD will parallel to the real horizon line. After checking everything is right, use MAN mode to launch the airplane.
  • Page 24 c) If your airplane can’t climb or turning and dissenting. It means the level fly position of your airplane is not calibrated right. Put your airplane to level fly position. And do the COMMON CALIBRATION in the OSD menu. 3) Next is the RTH. You have to set home when you flying the RTH modes.

When the airplane is in RTH mode, if the airplane’s altitude is under this value, the airplane will climbing to this number as soon as possible, if the airplane’s altitude is higher than this number, when your trigger RTH, the AP will consider the distance from home to do the altitude change.
  • Page 27 1.9 ROLL-D Rolling Damping parameter, to control the roll oscillating. range 0~30，default 5。 1.10 PITCH-P Pitch P, the bigger the value the more sensitive to control, too high will cause pitch oscillating, default 11。Range : 0~30， 1.11 PITCH-D pitch Damping parameter, to control the pitch oscillating.
