Front motors on the Mavic 2 Pro hot....hotter then the rear ones ?

[MavicFlyer2]

I've been laid up at home and boredom has set in. I decided to take the Mavic out and do some camera adjusting also some controller adjusting then finish up by flying around and landing. I had it up in the air around 15 minutes.
It was a warm/humid day (84° temp and 67° dewpoint) and after landing I felt the blade motors. Noticeable the fronts were quite a bit warmer then the rears with the front right (looking straight down) was the warmest motor of them all. Mostly the rear ones felt about the same.
I'm not sure what I should do ? I know not to lube them. I was thinking compressed air but would it be good to turn over the drone and blow the motors out that way ?

It's normal for the motors to get hot ... they have a lot of current running through them.
Why do anything?
Your drone flies normally doesn't it?

Yes it's flying fine as I can tell....I was curious of the differences of the heat change from each motor and wasn't sure how normal that is. That starboard front side is quite a bit warmer then the rest.

Agree it is normal for the motors one or even two motors just may be running at a slightly faster RPM that is normal I wouldnt put air into the motor UNLESS I could "feel" something inside. I will bet your drone is fine.

Thanks...I am feeling better about this now !

What controller are you using?
If you use a phone and the controller IS NOT an RC1B,.
SWITCH THE PHONE's WIFI OFF, connect the phone to your computer via USB, if you are using windows and an android phone use the computer to run a search for "MCDatFlightRecords", right click any folder it finds and lefy click on "open folder location". If the path show dji.go.v4 open the folder and check to see whether or not there are any .DAT files in there. If so copy them to you computer then either
1) upload the latest file to a file hosting site, make the page public and post its URL here, or
2) download CsvView from

CsvView Downloads

install it, open it and process the relevant .DAT then left click on "Motor Speeds"

Why switch the phone's wifi off ? Because there is a chance that a log sync with DJI will delete the .DATs, syncing shouldn't be an automated process but ......
If the controller is an RC1B it is unlikely that there will be any DATs, they don't seem to create them.

If you have no DATs fly another low hover in windless conditions to generate another DAT.

Since DJI sync is no longer active in the US, is this even a concern any longer?

Do you know when the flight was flown ?
Either way, better safe than sorry.

 

[MavicAir2Marc]

I was just asking the question since I don't know. I'm not challenging you.

Ok but it is still better safe than sorry, besides I have seen it written that use of a VPN can get around the USA thing.

Personally, I wouldn’t do anything. Motors always get “warm” to “warmer” and you were flying on a pretty warm day. Also, motors will get warmer depending on flight corrections and maneuvering.
Were you just hovering, or were you maybe ripping around the park ? IDK. Just my thoughts on it.

I was mostly hovering and not moving aggressively. Just moving from 1 side of the house to the other changing camera settings and shooting photos.

 

[Droning on and on...]

Depending on the wind, different motors can work harder holding position than others. For example, constant gusts from behind while hovering will cause it to pitch backwards to hold position, spinning up the front motors slightly and the rear motors reduced RPM slightly.

Over a period of this constantly occurring, the front motors will get warmer.

Because the Flight Controller in DJI drones compensates for wind and attempts to hold a course over the ground (not just a heading), wind can affect the motors in this way even if your moving around, not just hovering.

I didn't know the flight controller had any effect on sending higher RPM's to the different motors for flight stability !
I use DJI smart controller for fly the Mavic and it's going to warm up here again.
I'll test a few things out and see how the heat is distributed then, thank you !

If you can have a look at the CsvView motor rpm chart as mentioned in post 6

With using the DJI Smart Controller is the process the same ? I don't use my phone for flights.

If you use the controller to make the drone fly forwards, backwards, sideways, go faster or slower, climb, descend or rotate, the controller is sending instructions to change the speed of different motors to make the drone do what you wanted.
The flight controller is also varying the motor speeds to help hold position or maintain track against a wind.
That's just how drones work.

Assuming you find the "FlightRecord" folder you should see a folder named "MCDatFlightRecords", if so open that and you should see the DATs, that is providing any syncing has not deleted them.
If there are not DATs ensure that syncing is switched off and then fly a windless hover.
I would expect somehing like this

Thank you very much for sharing this with me, I appreciate it a lot.
It's a bit much for me but I'll tackle it and share it when I'm finished.

It becomes 2nd nature after a while, first time is always difficult especially when you are probably swapping between screens or tabs, reading instruction on one and trying to 'do' on the other.
