Hey there,
Actually I haven't yet, still waiting to decide, but I convinced a friend of mine to bu ...

Morph (and anyone else), Has anyone had a successful repair of this FW induced vibration issue? I have a couple of days left to RMA but I fear that DJI repair wont really fix it and I have been waiting patiently for a FW update fix. I get vibrations below 50 deg F. I can get rid of some of it with 80,80,80,80 gains but not all.

Hi guys,

I'm not sure it is the very same issue, but I stumbled into this interesting video explaining how to "Resolve gimbal overload/buzzing"


I saw it on an interesting site related to helping with various Phantom drones problems:http://www.phantomhelp.com/Phantom-3-Professional/

I've not heard of anyone who's had the vibrations repaired or even had the problem acknowledged by DJI other than by the forum moderators.

Has balancing the motors been tried ?
Very strange that this issue is so hard to find a solution to.
If it is software via the 1.5 and 1.6 update then it should have been easy for DJI to find the bug.

How do you propose to balance the motors? And why, if the problem only exists after a firmware upgrade, it has nothing to do with motor balance.

For me, this is my opinion.
If you take apart the machine will lose the warranty?
I have another 10 month warranty, but I feel this problem will not be solved.
I do not read here or elsewhere on the assumption that the only vibrating GPS mode. This is not true. I've constantly doing it.
Or is there a kind of vibration which is due to an electronic failure, mechanical, and we Indeed it occurs.

It may be down to the way it reacts to the gyros, hence adjusting gains to reduce it.  Gyros are used in all modes.  I'm expecting I'll be able to increase gains again when the weather warms up a bit as I only see the problem in sub-zero temperatures.

DJI-Ken Posted at 2016-3-8 21:26
Yes, from the people experiencing it, it is only on the older motors/ESC's.

If you are asking if you send it in for repair and the issue arises again? Then yes, send it back in to be repaired again.

When a firmware is updated the software coding / algorithms change. Maybe making the sensitive/ accurate to changes. This makes it even more important for the craft to be balanced and explains why lowering the gains helps to solve it. Usually it's just props that need balancing. Maybe a prop that is slight.y out from the mould or damage. Motor balancing would be very difficult unless you wound them yourself in a very strict way.

With the motors being such a small diameter & precision machined, it's not likely they'll have much of an effect.

"Motor balancing would be very difficult unless you wound them yourself in a very strict way. "

This is not relevant, the wound part of the motor is stationary and does not rotate. It would not matter how you wound them. The outer case containing the magnets would be carefully balanced at manufacture and will not change during operation.

Lol it's very relevant, how many winds and how accurately they are wound all contribute to the fine balance of the motor and the craft. Have you ever wound a motor?
Agreed on the casing and its magnets but even these can have errors on manufacture, that will not show in a working test but on balance will be slightly out.

I've wound and worked with enough brushless motors to know this is so.

Yes, I know about motors, I sell them. And seeing the design is an outrunner, where the windings are stationary, the number of windings and how accurately they are wound has absolutely no bearing on the rotational mass. How can the windings be out of balance if they don't rotate?

Geebax Posted at 2016-3-11 08:51

Balance works on symmetry. Crossed wires non-conforming cross section of wire etc all contribute to a motor being slightly different from the others and causing vibrations.

My dad sells cars. Can't fix one to save his life ;)

So I just contacted DJI direct and discussed about firmware upgrades. After, I pushed the boat out and upgraded. It is a myth that you have to upgrade in increments; if you are in 1.4 you can go,direct to 1.6 as I have done, as  the DJI tech team has said its ok to do.. Upgrade was successful, also my spare battery. Quick test flight no vibes but there was a slight drift but that could be due to having only 8 sats instead of the usual 17 I normally  get. Once it settled down it held pretty good. For sure the firmware makes it more sensitive (I can that that in the way it handles and flies must be in the algorithm) and therefore will respond to anything that is not in balance and create a vibration. Perfect props is a must  the next to check would be the motors. I've flown and built RC helis for many years now and often vibrations are caused by faulty motors as well as blades that are not balanced. Will take my p3 out for a good test run today and see how it goes. Fail safe max height already checked will do a compas recalibration as well before take off and ensure the new home point is set ;)

Not all are made perfect ;) in the tech world there are always inconsistencies. It's the nature of the hobby. Not that I'm dissing DJI quality is is well above the herd.

Check the housing is secure. Are any of the threads slipping?

The change in the algorithm for control is not a bug, it's just more sensitive which makes it more accurate. But slight physical discrepancies will be picked up as vibrations. This is why lowering the gains works as a fix.

No, nothing is perfect, that's the way the world is.  But, being so close to the axis of rotation, balancing wouldn't make a noticeable difference.  That's why most small diameter shafts or motors don't need balancing, only large diameter objects, like propellers, flywheels, large diameter cutting tools that run at high surface speeds, car wheel rims etc.  Notice they don't balance car brake discs, but they balance the rims once the tyres ore on?  Discs are close to the driveshaft & well machined, whereas tyres are moulded & large diameter.

Yes it is a less likely part to be faulty and off balance. But I have known faulty (poor manufacture either the magnets in the casing or the pinion is slightly bent) motors cause vibration else where in the craft. If all else fails rip it apart and re build it ;)

DJI-Ken, I sent them an email today, and their response:

,,Hello,

The tests were conducted inside and the video shows NO vibration. The copter will be tested outside this afternoon as it is raining right now. If everything goes well it will be sent out tomorrow."

The phantom wobbles and vibrates! I did not made that up! Can you please do something about it? It seems that the wobble and vibration depends on the air pressure/temperature. It vibrated when I flown in 10 degrees celsius. I really hope I won't get it back unfixed. :/

Anyone knwo if the new relised firmware solve something of the vibration problems?

Fermin Posted at 2016-3-15 18:31

Hi, it seems no...

I just updated to firmware 1.7.0060. I did all calibrations after that.
The outside temperature is 10 degrees celcius, and wind 3bft. Air pressure 1012 hPa.
First set all gains to 100.
P3P is vibrating a lot with this gain settings, so i lowered the gains back to 80,80,80,100.
Then still little vibrating in the P3P, but also  visible on the recordings!!!!!
With firmware 1.6.0040, i had vibrations on the P3P with lower gains, but the recorded video was good.
I will try all weather conditions, but for now it seems no solution came with new firmware.
If it has become worse, then i will go back to 1.6.0040.

Is it possible that after so long time (is enough to look at the first post) this WEIRD issue that involves a lot of P3 is still not addressed and solved?

Hi Cris, could you tell me your controller firmware version?  I've the vibration issue but i could go back to 1.4 p3 fw (I'm on 1.5 now)...

my controller Firmware is 1.5.70    , My go app is 2.43
and the Firmware on the P3P is 1.4  
My Yaw Gain is set to 80%
And i don't have any problems or Vibrations....
I flew today , and everything was smooth as silk.

I have observable vibration on the ground when idling. All my props are balanced. At some point, I swapped props with an extra set I had and vibration greatly reduced and I would consider it normal now. I never had any vibration in air though or video degradation. Ordered a few more prop sets just to try as it is very inexpensive.

Mine's stopped vibrating now, but it seems to be because the temperatures have risen as we come out of winter.  There have been no firmware updates to address the problem.

Any update on a firmware fix anyone?
It has been months!

I'm still seeing vibrations on a lot of footage. Argh!

SamJH7 Posted at 2016-4-2 07:40

It's unbelievable that a grave issue like that generated in a digital way by a new firmware is not yet solved after MONTHS and MONTHS. Then they asked why people is loosing confidence with DJI and noone would like to update when the bird fly fine. The main lucky of DJI is that at the moment the is no real competition on the market.

Anyway after tried to reduce all gains to 80% (a little bit better but still vibrating) i'll downgrade to 1.4 even if with 1.4 i had drifting issues, that's why i updated to 1.5.

Mine does the same on the ground in idle. Noticed after the 1.4 update
