Have you tried performing a cold IMU calibration on a levelled surface?

Yes. I completed good cals after both firmware updates.

Aloha Ken,

Just wanted to report that I just upgraded a P3P from 1.5 to 1.6 and the aircraft is now exhibiting the vibrations that everyone is complaining about in this thread.

The aircraft was fine before the update, and I have accumulated 8:32:00 hours on the aircraft.  I was skeptical of this issue when I saw one of the previous YouTube videos in the above posts, but I now see it clearly for myself.

One thing I did notice that when I looked at the upgrade log for the aircraft and the 3 additional batteries, I noticed that the datestamp on the log file is always reset to 1.1.2014 12:0X AM, with x being the amount of time it took to perform the update.

It looks to me like a bug in the firmware has crept in with some value getting lost or retained where it should not have been.

For example, I never flew the aircraft before upgrading to 1.5, as I wanted the waypoints and POI features from the start.

Your suggestion about reverting to 1.4 and then back to 1.6 makes sense in this case, and when I have the time I will probably try this if the other suggestions don't pan out.

One thing that is irksome is that there is not an easy way to find out how to do all the MC, IMU and Gimbal recalibrations from within this thread.  It would be convenient, but at least it will force people to become more familiar with the device, whether they want to or not.

Can you point to the procedure to acquire a DAT file for review?

Thanks in advance

I had the same problem, but mine would start vibrating while sitting on the ground with the rotors turning at idle. The first sign of trouble was a noticeable increase in the RPMs of the rotors at which point it would start to vibrate.  It would start within 30 seconds of the rotors turning. Once it started to oscillate I couldn't stop it unless I shut it down or lifted off the ground.

In the spirit of full disclosure, I did crashed it previously on landing, tipping it over and damaged two of the blades.  I replaced all 4 blades to make sure I didn't have an out of balance blade issue. I did fly it and it flew OK, although it didn't seem as stable. I downgraded and upgrade the Firmware with little noticeable difference.

I just finished about 2 hours of troubleshooting and this is what I found.  I read the other posts and played with the Gain settings. They were all at 100%. I adjusted them independently to see if I could stop the vibrations. With my aircraft , if I adjusted the YAW gain setting to 90% it would not oscillate and ran for over 5 minutes with no oscillation. I raised it to 95% and still no oscillation. If I raised it to 100% while the rotors were turning, the copter would start to oscillate. The RPMs would noticeably increase and then the copter would start to vibrate. If I dropped the YAW gain setting down, the copter would still vibrate. Once it starts to vibrate I had to shut it down to stop it from vibrating. I tried both versions of Firmware, 1.05 and 1.06. With 1.05 I could raise the YAW gain to 95% and it wouldn't oscillate. With version 1.06 I had to drop the gain to 90% to stop the oscillating. I am by no means an expert and this may only apply to my aircraft. It seems to enter into a oscillating feedback loop, which once it starts there is no way to stop it unless you shut it down or take off.

Once again this may only apply to my aircraft, but hope this helps someone.

Hi John,

I made more or less the same experience:
http://forum.dji.com/forum.php?m ... &fromuid=127639
Although my "basic gain" values for non-oscillating in ground idle (yaw), hover/inflight (pitch&roll), climb (vertical) differ a bit from yours:
pitch=90%, roll=90%, yaw=80%, vertical=90%.
Maybe these about 5 or 10% lower values are due to the fact that I tested in some gusty/variable winds of >7m/s.
The reduced "basic gains" cured my oscillation trouble and concerns that came with v1.5/1.6...

Greetings,
Claus

Ken - please review the attached video - very clear indication of vibration induced by FW 1.6 upgrade

Count me as another FW 1.5 to 1.6 upgrade introducing vibration. Upgraded to 1.6 right after Christmas. Performed IMU cal, compass cal, and was unable to get focused long exposure shots. Yesterday, I spent more time hovering trying to see if there was an issue. I experienced some drift and uncommanded altitude changes but nothing definitive. However, after examining the subsequent flight video, the shaking starts at 10 seconds and becomes very pronounced at the 30-50 second mark in the attached clip. Very disappointing after purchasing my P3P in August and completing 40+ flights with no vibration whatsoever. This P3P has the old motors. I'm guessing a yaw gain problem based on the video.

My son has a new P3P with new motors so I'm going to look at his flight videos for vibration evidence.

DJI - please consolidate how to troubleshoot and fix this apparently widespread issue in a new sticky. Reading through this entire thread for how to post DAT files and adjust gains etc. is very confusing and time consuming. TIA

Wow!...mine was never that bad.  The problem started between firmware 1.4 & 1.5, did you skip 1.5?  You may have already had the problem but not noticed or it wasn't as bad due to different temperatures?

nigelw Posted at 2016-1-3 08:50
Wow!...mine was never that bad.  The problem started between firmware 1.4 & 1.5, did you skip 1.5?   ...

I did 1.4 to 1.5 to 1.6.  From looking at the videos I have with 1.4 and prior  (rock solid, no issues), 1.5 (only a couple of flights - will look at these again), the 1.6 video (link above from yesterday) was the first indication of a pronounced and prolonged (10s of seconds) vibration both in hover and maneuvering.

I carefully checked for any structural issues - arm cracks and I have none (so far). I think I'm grounded until DJI comes back with a definitive fix.

I have also flown in various wind conditions (yesterday was moderate) and this 1.6 flight was the first indication of vibration.

Update: checked 4 videos from my son's P3P with new motors, upgraded to FW 1.6, same day, same wind conditions as the video above and it's rock solid. So that's my small sample size of 1 new motor P3P compared to 1 old motor P3P with FW 1.6 upgrades resulting in only the old motor P3P having vibration issues.

Update 2: Downgraded FW to 1.5. If anyone else is downgrading. you can only go back sequentially, e.g. 1.6 to 1.5 to 1.4, not 1.6 to 1.4. Goimg to very carefully check out the old motor P3P with FW 1.5 since I dont think I had an issue with it, just FW 1.6. Downgrade logs:

in mine the vibration is in the drone, not the video. the problem is not in the old engines

Dan30 Posted at 2016-1-3 16:17

Dan, Perhaps your drone vibration is damped out by the camera. I'm guessing mine is more severe such that the gimbal/camera can't damp out the vibration I'm experiencing. I also have 2 P3Ps - one with new motors and one with old motors and the new motor P3P isnt having any noticeable vibration  with FW 1.6.

Update 2: Now with FW 1.5 cold soaked the old motor P3P, kept batteries indoors. Performed IMU, gimbal cal. Outside temp at flight time was 34 F and dropped to 33 F at finish. Had “MC signal error” twice at drone startup. Kept cycling power on the drone (alternating normal, MC signal error, normal, MC signal error, normal, normal and then launched). Shot some video from phone on ground and in hover at 6+ feet = no apparent issues, some drifting but no alt changes. Was cautiously hopeful in flying the same path but the vibration was still apparent, perhaps not quite as violent as the earlier video. Will post video shortly but video recording with the drone in current state (FW 1.5 or FW 1.6) is unsatisfactory as compared to how smooth it was in the previous 40 flights.

Now I’m trying to decide whether to downgrade further to 1.4 and lose the advanced flight modes or soften the gains.

Hey DJI! Let me know what you want me to try!

bletzinger 331, you can not go from 1.6 to 1.4 not? According to Ken he told me you can only down to the 1.6 to 1.5. if you can go from 1.6 to 1.4 please let me know

Sorry about the confusion -  what Ken said is true. Not 1.6 to 1.4 direct but you can go 1.6 to 1.5 to 1.4 : in steps.

update: vibration still present after downgrading to FW 1.5

Unfortunately I have to add my October 2015 purchased P3P to the list of vibrating drones. I am brand spanking new to the forums, driven here by my issue, and honestly stunned at the amount of people having the same problem. Mine also seemed to start after the 1.6 update. Vibrates on idle and also when hovering right in front of you. I have tried downgrading to 1.5 and back to 1.6 again, calibrations, all to no avail. Forgive me for not going through all of the (9 pages now) of reports on this issue, but what do I need to do now?

Dan30 Posted at 2016-1-4 05:02
thanks!! then can you confirm that? and what about the RC carries the latest update? and the app?  ...

Confirmed. From reading the 9 pages of this thread, I dont think the RC controller FW is an issue. Im assuming DJI wouldnt let us upgrade/downgrade between drone FW 1.4 to 1.5 to 1.6 or 1.6 to 1.5 to 1.4 if the drone FW conflicted with the latest RC FW. I sure wish DJI would respond with either a fix or an official trouble shooting process for this issue since they released drone FW 1.5 and 1.6 that apparently caused the vibration issue with the old motor P3Ps. My best guess is that the gain values were either corrupted by FW 1.5 (some residual value) that only appears (in my case) to affect the old motor P3P or that FW 1.5+ is incompatible with my old motor P3P.

So absent hearing a response from DJI, you can try the time consuming process of going back and forth FW 1.4/1.5/1.6 on the drone to hopefully fix a residual value issue or you can soften the gains from 100% down to some number (especially the yaw) to dampen out vibration. Im probably going to try the gain adjustments next. Gain adjustments are better described in the "New Firmware for the Phantom 3 Series thread".

Its really not right , that we ( people with older motors ) should have to play with our gains to try to get our birds to not vibrate and fly right , with anything
passed 1.4 firmware , I realize the new phantom 3 with new motors are not having as much problem with this , But i assure you there is a lot more p3p's out there
with older motors than there are with new ones , thousands of people are having these problems that have older motors with 1.5 and 1.6 firmware.
And DJI needs to stop development of everything they have and work only on this til its fixed. it is very serious , And there is no need to try to send flight
data of every single P3P pro that is vibrating , cause DJI techs can not go though thousands of drones data. Everyone is having the same exact problem.
There needs to be Firmware for p3p's with older motors and Firmware with p3p's with newer motors , Cause there not the same anymore.
The same firmware is not going to work on both drones. I think this has been proven over and over.

The simplest thing to do would be let us with older motors go back to 1.3 on our controllers and 1.4 on the drone and we will
be fine , I as most others P3P with older motors worked perfectly with 1.3 on controller and 1.4 on the drone.
Ever since the controller was updated to 1.5 , everthing has been a mess for older phantom 3's
Just let us down grade everything and the problem will be gone.

Please make sure that you disable synchronous follow.  That will amplify the yaw on the the gimbal.

Hi, the problem is the body vibration caused by New 1.5 and 1.6 firmware.
Propellers ok, motors too...
Before upgrading firmware it worked fine and something went wromg after.

Hey Ken I just wanted to say that after 5 tries with the downgrade and upgrade back to 1.5.0030 followed by a cold IMU and compass calibration the arm vibrations have finally stopped.  I did mess around with the gains but it didn't help but as i said they are gone now.  I am just wondering if it would be a good idea to hold off upgrading go the new 1.6.004 for a bit to make sure it doesn't act up again.  Your advice is greatly appreciated.  I want to take advantage of the battery firmware for cold climates in the new firmware but I'm a little worried because I won't be able to go back down to 1.4.0010 when I go to 1.6.004.

Thanks!

I have come to the conclusion , there not going to fix the problem. 2 months now , Thousands of P3P with old motors vibrate , crash , and fly a way's , not one Firmware
fix for 2 months ,

Thanks MikeDrone7. If you have the time please describe the sequence you used. I'm guessing 1.5 to 1.4 to 1.5 to 1.4 and finally back to 1.5. Did you do any cals in between? I'm going to try and replicate your process next week. I still have the vibration after a downgrade to 1.5 but I havent tried going back and forth between 1.4 and 1.5.

I'll summarize where I think we are with old motor P3s upgraded to FW 1.5 or FW 1.6 that induced a vibration, since we havent heard from DJI in a while:

1. Try MikeDrone7s process above.
2. Lower the gains to pitch=90%, roll=90%, yaw=80%, vertical=90% as described here link by vr-pilot Note: in my case I think it's a yaw problem.
3. Start the RMA process
4. Wait for DJI to post a fix for old motor P3P vibration caused by FW 1.5/ FW 1.6?

I'll try #1 above and give DJI a few more days to respond, but if they dont publish a fix (#4), or at least tell us if they are making progress, then I'm going to RMA my old motor P3P (#3). I also have a new motor P3P (with FW 1.6) without the problem so I'm confident the FW 1.5/ FW 1.6 upgrade caused the vibration on the old motor P3P so DJI should just fix it.

There are not thousands of people with the vibrations issues, yes there are some with the vibration issue from the older motors but it's probably less than 1% of the Phantoms with the older motors.
It is a warranty issue if you cannot fix it, go tot the support center of the DJI website and send it in for warranty repair.
All I know is they are working on it in China and will probably have a fix in the next firmware update.

Your P3 Standard is only updated from WiFi through the app. There is no firmware that you can download to an SD card.

I think everyone needs clarification on warranty regarding upgrades.
Apparently this vibration problem is a real issue.  (As were many others)

Yet, is it true (or false)  that if you do not upgrade, your warranty is void?
