4) AK4000 comes with more accessories, comparing with AK2000, like carbon fiber extension pole and AKF I.

10. Can I switch on gimbal without balancing it with camera installed?

Switch on gimbal without balancing might lead to shorter run time, vibration, high temperature of motor and other problems. Thus, balance your gimbal with camera installed before turning it on is strongly recommended.

11. How to balance AK series?

Before switching on AK series, you need to mount camera on it and balance it on three axes: tilt, roll and pan axes. Another thing is that, if other accessories should be attached to gimbal, like lens support frame, follow focus, extension support of tilt axis, mount them on the gimbal before balancing. Please refer to the tutorial for installation and balancing of AK series.
https://www.youtube.com/watch?v=GURE5vzqg5E

12. What is a properly balanced gimbal?

By following steps you'll know the gimbal (it's off) is good to go.
Tilt/Roll axis: place the gimbal on a stable surface (in upright position), the camera holds at any place no matter where you point it to.
Pan axis: the vertical arm is in parallel with the ground when you place the gimbal in horizontal position.
Please refer to the first part of this video to check perfect balance state.
https://www.youtube.com/watch?v=HV4SHFH4wzc
And the balance steps please refer to following video
https://www.youtube.com/watch?v=GURE5vzqg5E

13. Is the motor location interchangeable when mounting camera on AK2000?

The tilt axis AK2000 can rotate 360°, and tilt motor can be placed on either side of camera.

14. After turning gimbal on, it vibrates for 3-5 seconds, and then stops. Is it normal?

After turning gimbal on, short time's vibration happens because the motors match with different cameras automatically, which is a normal adjusting process. You don't have to adjust motor strength by yourself. It will work fine after automatically finishing the adjustment.

15. Gimbal is perfectly balanced but keeps vibrating and buzzing, what should I do?

That happens because the value of motor strength is too big for your camera. Please choose an appropriate setting by touch screen. Alternatively, choose "Auto Adaption" then reboot gimbal in order to get this function to work.
Please refer to vibration issue 2 of the video below.
https://www.youtube.com/watch?v=HV4SHFH4wzc

16. Gimbal functions properly in upright position, but it vibrates at certain angle or in upside-down position (buzzing). How to fix it?

Follow these steps to remove vibration.
1) First check whether or not gimbal is properly balanced. Please refer to Question #12.
2) If gimbal is perfectly balanced, but when it is at certain angle or in upside-down position, that changes where the center of gravity is, and might cause vibration. So the suggestion is to check whether or not screws are tightened, support lens frame is just next to the lens, and the camera touches tilt motor (if possible).
3) If things above is done but vibration still there, please choose "Auto Adaption" by touch screen, and then reboot gimbal. Please refer to vibration issue 3 included in the following video.
https://www.youtube.com/watch?v=HV4SHFH4wzc
4) If nothing changes, update Gimbal Firmware V1004 by Feiyu ON App is recommended. Please refer to the attached below.
https://www.youtube.com/watch?v=1Rx7TIZ3agk

17. Gimbal wobbles after switching on, what should I do?

If gimbal is perfectly balance (please refer to Question #13), but move from side to side without noise after turning on, it seems likely that there is not enough strength from motor to support camera. Please change the setting of Payload via touch screen, or choose "Auto Adaption" then reboot gimbal to make this function work.

18. How to adjust motor strength of AK series?

Motor strength can be adjusted by two methods.
1) Change the setting of Payload via touch screen, or choose "Auto Adaption" or customize. 5 shifts of Payload are listed below.

Note: there might be a deviation from the corresponding payload, choose the right one based on your usage.
2) Adjust motor strength via Feiyu ON, and save the settings as custom 1/2/3 which then can be found on touch screen. Alternatively, choose "Auto Adaption" then reboot gimbal to make this function work.

19. How many ways can AK series connect to camera and control it?

1) Shutter release cable: connect AK to camera by shutter release cable, then you can control camera to take photo by shooting button on gimbal. Part of cameras, like Sony A7M3/ A9, Canon 5D 3/4, 6D2, Panasonic GH4/5, can be controlled to record by shutter button (camera is in video mode), because the camera is provided the feature that the shutter of camera is set as a start and stop button of recording.
Note: recording button on gimbal is only available to WiFi connection.
2) WiFi: choose the corresponding brand and model of camera in Feiyu ON App then gimbal can connect to the camera by WiFi. The control function varies with each camera.

34. How to shoot Motion Time-lapse with AK series?

A Motion Time-Lapse video is created on the basis of pictures shot by the camera that is set to take pictures at a certain speed with a gimbal that is moving at constant speed.
Here are the steps:
1)Connect gimbal with the camera via shutter cable and make sure AK could control the camera to take pictures.
2)Find "Rotation Time" on touch screen, and set up four parameters "PAN", "TILT", "INVL", and "DWELL". Set up exposure time on the camera as well with the value less than or equal to DWELL. The minimum value of DWELL is 1 second (2 seconds or above is recommended).
Note: PAN means the movement time on setting path of panning axis , TILT means the movement time on setting path of tilting axis.
INVL means the time-lapse intervals, which is set up more value than DWELL.
DWELL means the immobility time to make the camera exposure ,which is suggested to set up the same value as camera exposure time.
3)Find "Auto Rotation", follow the prompts on the touch screen to set up initial position and ending position and the route between two position When set-up is done, gimbal rotates automatically as programmed.
4)The time remaining shown on touch screen. Gimbal stops at the ending position when auto-rotation is done. Double click trigger button to reset gimbal.
5) Edit the pictures to timelapse video with some video edit software.
 

35. How to shoot Motion Time-lapse at night with AK series?

A Motion Time-Lapse video is created on the basis of pictures shot by the camera that is set to take pictures at a certain speed with a gimbal that is moving at constant speed. However, a Motion Time-Lapse at night requires long exposure while taking pictures, so that those pictures are of high quality could be edited to a video.
Here are the steps:
1) Connect gimbal with the camera via shutter cable and make sure AK could control the camera to take pictures.
2)Find "Rotation Time" on touch screen, and set up four parameters "PAN", "TILT", "INVL", and "DWELL". Set up exposure time on the camera as well with the value less than or equal to DWELL.
In order to determine what exposure time you should use, it is very important to take some pictures to find the best exposure time for your sample.
The max value of DWELL is 58 seconds. However, 55 seconds is recommended as the max value of DWELL since the camera will take some time to save pictures. If DWELL was set at 58 seconds, there will not be enough time for the camera to save picture but to capture again.
Note: PAN means the movement time on setting path of panning axis , TILT means the movement time on setting path of tilting axis.
INVL means the time-lapse intervals, which is set up more value than DWELL.
DWELL means the immobility time to make the camera exposure ,which is suggested to set up the same value as camera exposure time.
3) Find "Auto Rotation", follow the prompts on the touch screen to set up initial position and ending position and the route between two positions. When set-up is done, gimbal rotates automatically as programmed.
4) The time remainning shown on touch screen. Gimbal stops at the ending position when auto-rotation is done. Double click trigger button to reset gimbal.
5)Edit the pictures to time-lapse video with some video edit software.
Here is a tutorial for reference.
https://www.youtube.com/watch?v=H_C5vaccRAk&t=20s

36. Is there any tips for me on set up Rotation Time for a Motion Time-lapse?

Note: PAN means the movement time on setting path of panning axis , TILT means the movement time on setting path of tilting axis.
INVL means the time-lapse intervals, which is set up more value than DWELL.
DWELL means the immobility time to make the camera exposure ,which is suggested to set up the same value as camera exposure time.
When set up those four parameters "PAN", "TILT", "INVL", and "DWELL", you should follow the rule: PAN and/ or TILT>INVL>DWELL. Otherwise, you will get an error and have to set up the parameters again.
Besides, when DWELL is given a value greater than ZERO, gimbal sends a shutter signal to the camera 1 second after it stops rotating. If DWELL was set at 1 second, the camera would take picture while it is moving, pictures took might be kind of blur. Thus, it is recommended that DWELL is set as 2 seconds or above.

37. Gimbal connects to the camera via shutter release, however, the camera does not take picture when press the shutter button, what should I do?

Please make sure connect the shutter release cable with the camera and gimbal in right sequence first.
1) Check whether or not the camera can focus by half-pressing the shutter on the camera, and whether or not the camera can take picture by fully pressing the shutter. If not, please change the view direction of a lens to some position from a distance, it will be better to focus. If turn the camera to a mirror or display screens or something too close, it's hard to focus.
2) Check whether or not you use the right shutter release. The shutter release cables provided are for Sony S2 interface, Canon N3 interface and Panasonic L1 interface. The cable for Panasonic L1 port is not adapted to Canon 80D/ 700D.
3) Check whether or not the shutter release functions properly, and could control focus and photo-taking. Here is the video to show you how to check if the shutter release is in good condition.
https://www.youtube.com/watch?v=xG2w39SXeYc
4)If both the camera and the shutter release work fine, the problem might be involved with compatibility. Please check with official technical supports.

38. The joystick can control the camera tilt up or down, but it can not tilt up when at a certain angle, how to fix it?

If the joystick can control the camera tilt up or down, that means the tilt axis functions properly. It can't rotate in certain angles, especially vertically upward direction because the motor strength is not big enough for supporting the camera. Maybe the camera is not well balanced, or you balance the camera when the lens is not zoomed, and the automatic adaptation motor strength fit for this state. But when zoom in the lens, that changes the gravity of the camera. The motor strength provided may not support the upward movement of the camera.

39. When I use the rolling 360 degree rotation function, gimbal will stop at certain angle, how to solve this problem?

If the gimbal stop at certain angle on roll-controlling, that mainly because the gimbal is not balanced well before powering on, especially the panning axis, leading to a heavier weight on one side, so the motor can not support its rotation. Also if the lens is much heavier or quite longer than the camera body, that may cause this problem, too. Please well balance the gimbal following the tutorial on the website or APP.

40. The gimbal can stay stable after powering on, but why can’t I control it by joystick?

1) Please check whether or not the contact pin can rebound by single taping them, and if all the pins are in good condition. We can see the contact pin is already damaged as below.

2) Please turn the gimbal off and pick up the handle part, find soft cloth together with small amounts of alcohol to clear the contact pad on the top of the handle, as the picture shown, and dry it up.

3)Please try to update the firmware to check if it would help.

41. How to initialize AK series?

1)Slide the screen left ,then click Settings-Calibration.
2)Put the gimbal on a steady flat, as the picture shown.
3)The gimbal will automatically check whether be put on a steady flat.
4) After the screen shows “Calibration Completed”, pick the gimbal up, click ESC on the screen to finish calibration.
5) Please repeat the steps above if calibration is failed.
 

42. What kind of issue can be fixed by initialization?

1) When camera is not balance.
2) If not use for a long period of time.
3)In case of extreme temperature variation

43. How to fix the issue that the gimbal is not level?

44. Can I mount smart phone on AK series to do face/object tracking?

Yes, you can do face/object tracking with smart phone on the gimbal. But you have to balance the smart phone firstly because smart phone is lighter in weight, extra counterweights should be added so that the phone could be balanced properly with AK series. When gimbal is perfectly balanced, connect it with Feiyu ON APP then you can do face/object tracking.

45. What do the symbols on touch screen mean?

46. What can magic ring do? Is it able to control all the cameras to follow focus/zoom?

Magic ring has two main functions: three axes control and follow focus/zoom. Up to this point, the cameras can be controlled to follow focus are Canon 80D/ 60D/ 60D Mark II/ 5D Mark IV/ Panasonic GH4/ GH5S, ect..
Sony cameras are not able to do this because its protocol is not open-source. External follow focus unit is needed if you would like to have Sony camera follow the focus.

47. What is the difference between magic ring and the joystick on three axes control?

Magic ring can precisely control three axes with different settings of the sensitivity, which the joystick cannot do. Magic ring can give the user a greater sense of control to simulate simple wheels, which may be better than the joystick.

48. Magic ring makes a noise when I rotate it, what should I do?

Maybe the lack of damping oil causes noise when rotate magic ring. If you do not know how to fix it, please send your gimbal to us for repair.

49. Can I change the sensitivity of magic ring?

Slide touch screen to the right, click the scroll setting-->sensitivity, then you can adjust the sensitivity of magic ring by pushing the joystick left/right.
