This loudspeaker is pretty impressive , sound way above its weight.

Hi there. Thanks for sharing your feedback with the new Mavic 2 Enterprise. If there is any help needed, please don't hesitate to reach us. Thank you and have a safe flight always.

Wow. Looks impressive indeed.

Nice one thanks for sharing it

Quite impressive indeed, thank you for sharing!

what is more impressive is how they mount a speaker with that output '(think speaker magnates) that close to the imu compass without errors

do you get lateral drift on long straight runs?  still can't get my pro to fly straight or get rid of same yaw drift after turns

Most drones don’t get lateral movement and I’ve seen one person with M2 I see one other with Yaw movement here for Mavic Pro, I think a simple PM to a moderator and give her/him your logs and they might tell you what your problem is, with .400 there were great improvements to stability of Mavic Pro and we see almost no one complaining, with .500 for MavAir we have see huge reduction in Yaw problems and although some saying it’s still there for them and a few saying it came for them in .500, the numbers are very small.
I think the fact that you are having problems with all your drones you are not going to get them sorted until you get dji to look at your logs.
I don’t think trying to manufacture problems for other aircraft is going to help you get yours fixed.

hallmark.. I don't think that YOU GET ... that I already know what the problem is.. yaw vs yawmag.. and I have analyzed my logs pre and post firmware update...

yaw v yawmag diversion didn't exist with the old firmware, and after, all 3 of my drones have the same yaw v yawmag diversion in the csv data...

I, and others, arentt making this sh*t up for giggles.. and its not subjective.. these are hard numbers coming from the aircraft dat files...
The line to look at is the lime green.. that is atti_yaw(inu) - magyaw .. ie the deviation.. it should stay close to zero and be rather flat... this was just a quick up and down flight of a couple minutes and a rotation or to.. and look how far off it is at landing even haven been given a chance to settle down and catch up to itself...

me too - i am up to date on all devises on latest firmware yet can not fly straight.
Today i spent a certain amount of time flying with the purpose of trying to fly straight because i generally feel that my drone is drifting and wanted to pay strict attention to that.
No doubt in my mind my drone is drifting - i paid specific attention to my stick inputs and am now certain that my drone drifts - this is quite annoying.

I think it’s fair to say Bakaru, that it is not long since you reported and posted your crash, so for you it might be better to get your craft looked at.

You need to show exactly what Aircraft this is for seen as you didn’t mention it, we have all seen these before but in order to know what happened you need also your flight log which would show where you took off from as well as a lot of other stuff.
I will point msinger to this file you have posted he is by far the best reader of these files he might be able to tell more about it.

it is possibly related to my crash but since everything else works perfectly  (like absolutely every other function of flight and camera and gimbal movement) i am more inclined to believe it is software related.
Unfortunately sending it off to be checked is actually a bit of an issue and therefore will be left as a last resort.
Till then i will simply learn to fly in a way that compensates for the drift.

The biggest problem with crashes is nearly always IMU problem your IMU is the main item in your aircraft that will give your aircraft the correct attitude,

What others, this is forum for ME you seem to be on a pointless mission trying to prove that your problem is somewhat Endemic , which is just not true.

ok - good point - had not considered that.
I will do a few more test flights to pay attention to attitude and pay attention to see if the drift occurs in reverse and sideways flight also.
After some more test flights i will do a imu recalibration and take it from there.

IMU "Inertial measurement unit" .

As far as I see it, IMU calibration on a level surface updates a table of values the flight controller software uses as a reference for a level stationary hover. From there the craft responds predictably to flight commands.  It also likely measures any sensor noise and thermal drift so that these technical imperfections are accounted for when using IMU sensor data in flight. - this is likely why there must be no vibrations during the calibration process.


Bad IMU calibration could cause drift and attitude issues as the flight controller fights to hold the craft in what it thinks is the correct attitude as opposed to the correct physical attitude.


The IMU usually has 2 types of sensors – angle and acceleration and in turn 3 sensors of each type measuring in the X,Y and Z axis. These sensors can, through vibration, aging, impact etc, drift in their response over time and thus an IMU calibration will establish a new reference for the IMU’s level/stationary state that the flight controller can work with to restore stable flight.


Think of calibration as the bringing back into line the measured craft attitude with the true physical craft attitude.


As to how often an IMU calibration is needed, Refer to your manual ; certainly after any impact or if there are suspicions the craft can’t hover in a level attitude in a windless environment. Also after a firmware update is a good opportunity just in case the stored values get corrupted or are incompatible with the later firmware.

thank you - a very good explanation - i appreciate you taking the time to explain to me.
with this better understanding of imu i will be able to observe/analyze my drone behaviour better.
Thanks again - much appreciated.
btw - cool video posted at top of this thread

Pre FW update, you will read nothing to do with FW for Mavic Pro

Pre Last FW update for Spark.

that csv is from my mavic.. and there certainly is a difference in the average yaw-magyaw deviations pre and post updates  from .03.0700 to .04.0100

and I am not looking at the yaw as it swings through 179 to -179 I am looking at the average deviation starting at take off of 3 and landing with 20+ and that was just a quick up to 200ft out to 1000 ft a couple turns and RTH back..

if I pull a trace from a 20 minute flight with dozens of turns the yaw-magyaw separation gets larger..

when it deviates significantly enough it results in a atti... period.. now just go away....

Wow that's incredibly impressive speaker on the Enterprise. Glad that dude tested the distance in 100 increments.

This is very impressive. Thanks for sharing

Again my post was simply to show that mag Yaw is not caused by FW , so it might be futile waiting for FW fix, I’ve owned spark since it was released and Mavic Pro and in both these craft we have seen this mag Yaw and has always been associated with compass/gps problems.

and you know this as fact how>?

firmware most certainly can change how yaw, magyaw, atti_yaw, gps heading.. pure accelerometer data etc can be 'blended' by the complimentary filter and also show differences in how each of those sources are filtered or dampened now .. look.. I know more about this than you ... ok pumpkin...

Well that’s it you know so much, I can fly all my aircraft and so can the vast majority, you can’t fly any of yours, so what does that tell you about all you know. Cutie Pie.
This thread was supposed to be about ME , you seem to trying to change all threads to get on to subject of mag Yaw but it’s not really working for you.

Thanks for sharing your feed back, i just wanted to know if we can have a separate on/off mic button on the mobile sdk. thank you in advance

sounds great, thanks for sharing

I just got my M2E and it exhibits the same issue. The M2E was a rush to market for CES, if you ask me. Give it a year and a few price drops....

I've always thought a speaker would throw off the compass on a drone and put the drone into a wild flight.

How does the Mavic avoid this condition?   Magnet-less speaker of some sort?

My experience with adding a speaker on my Spreading Wings 1000 is that it seemed to be the culprit for an erroneous flight that caused $5,000 in damage (not even including my busted S1000.
