As the title suggests, if I tilt down, the servo movement is very jerky and makes the video unusable if filming at the same time.
Air2Air have given me a couple of suggestions to try and say that the best shots are taken with the camera tilt set up beforehand. I don't agree and can see situations where I'd like to dynamically tilt as I'm filming.
Anyone else get this?

Sounds like servo problems to me.... touch wood, so far so good for me.

I had the same problem. Here's what I did to fix it:
1. I setup the X6 on the kitchen table, installed the camera and then tilted the camera mount through its full range. Then reposition the camera, try it again and repeat until the movement was smooth. On mine, the mounting position is towards the front of the camera mount.
2. The other thing I did (not sure if it helped or not) was move the linkage in one position on the servo arm. The idea was too reduce the load on the servo.
3. One other thing to check. Are the mounting screws that fasten the 2 sections (camera mount & fixed bracket) together too tight? If you're repositioning the servo linkage, check to see if the camera mount swings freely while you've got the linkage disconnected.

Hi Rob. I'll try those. One thing that I didn't mention is that the servo can't always settle. In a lot of positions, you can hear it buzzing as it tries to adjust. By tilting slightly you can kill it, but it does sound like a stiff / badly set up linkage so will try your ideas. When it's buzzing, I guess it's draining the battery faster, reducing the servo life and also interferes with my (crappy) video downlink. Not good.  |

Even with my TREX700 I always take the time to balance the camera on the mounting plate and assume your set-up is pretty much the same. I disconnect the linkage and then find the balance position - tighten everything down and the servo is happy, it doesn't buzz and the action is smoother. When you change cameras or add a different lens you re-balance. Hope this helps for you too.

Did that help to set it in your kitchen??
I have the same problem and do not want to just set it and leave it there! This needs to be adjustable while filming usable footage.

Hi Joe, the buzzing that you hear is the servo under load. In this condition the battery will drain very quickly. I fly large model aircraft and each servo and surface are balanced for full and free movement.
The setup does take time to do but your servo should not be hunting under load. Something somewhere is either misaligned or unbalanced. Of course once air pressure is added well who knows what goes on up there!!

Something somewhere is either misaligned or unbalanced. Of course once air pressure is added well who knows what goes on up there!! Had a play tonight. Loosened the bolts a bit to free the assembly up. Servo still hunting. What I have noticed is that there is a link from the servo. One end fits the servo toothed wheel, the other houses a ball socket, which is fixed to a rod linkage (which then goes off to the gymbal (via another ball joint). Although the rod to gymbal ball moves freely, the servo link to rod does not, it is fairly stiff so perhaps this is not helping These servos don't seem particularly manly either. Think I'm going to have it sorted under warranty as the servo hunting not only drains the battery faster (as the OP mentioned) but also generates interference on the video downlink. |

I already have to change 3 servo motors, how ca I make that the move will be soft and stable.  ? |

Also check if the cables rub against the camera's screen, that gives the servo more resistance.

Could it be the potentiometer on the hand held controller which is malfunctioning?
I have the same humming in the servo and just touching the tilt knob will stop it. Try moving it from side to side gently, (not turning the knob) and you'll see the humming starts and stops.
Also this knob could be easilly damaged when it is introdused back in the transport case.
Someone thinks this could be the problem too?
In my case, only for the videocamera mount, I can not use an original servo. It will surely burn as it did three times. I'm using a different one and no problem (just the humming, but won't burn).
