I already tried to get help in another thread 'Phantom 3 Series firmware update', with no luck (no wonder, with so many users complaints recently!)
So here is my issue in a stand alone Thread:
My problem is very short range of my RC controls (5ghz) and losing signal, while video transsmission (2.4ghz) works fine.

I'm fliying in CE mode and the very max range i got is 125m (before and after the update), i'm flying out in the open (I have tried many diferent locations out in the fields), with no/minimal interference, fliying at 50m altitude (not directly above me), antenass pointed corectly. My wifi strength meter is showing most bars at all times, I have never lost the video signal. I'm losing 5.8ghz controlls signal, even while indoors. Strenght meter for RC signal usualy drops before the bird reaches 100m distance, and the aircraft goes to RTH.

Firmware: Aircraft (P3 Standard)- Version 1.4.60+
App version- 2.7.1 for ios,
My log file after the last firmware update shows: device not detected on modules 7, 11 and 12 (i'm not sure if tha's normal). The firmware update was sucesfull.

I have relinked the aircraft and the RC and tested it in an location uphills away from any interference. Max range I got yesterday was 125m, at 70 m altitude, then the signal was lost (repeated many times) and the aircraft goes to RTH. I noticed that the signal was lost quicker when I turned the drone (yawing).

Today I've done RC controls calibration- not tested yet, should i do another cold imu calibration (it was done just before the recent update)? I can post the entire log file if it's any help. Is there someting I can try on my own before I send it in for repair? I'm a bit sceptical, as I read many users complain about the DJI suport.


Appreciate any help!

I can't say what those modules, 7, 11 and 12 are, but hopefully a DJI person will come on here and tell you what those modules are. I suspect they are important, and if those messages are in the file, it tends to suggest the update was not complete.

I just tested the range again after calibrating the contolls and imu. Max range I got today was 120m.

I noticed two things:
1.  that even in very close range (less than 10 meters away from me, altitude was no more than 2m) the signal got weaker/lost while in a yaw.
2. While flying straith forward the aircraft starts to jerk just before losing connection.
Is this normal in CE mode?

It sounds like you might have a broken antenna.

I've read several threads on here that described a new P3S owner having range issues traced back to a broken antenna in the RC unit.

I also had poor range with the Standard but the other way around, lost video after sometimes only 10m. RC control was better but flying without video is useless.
My solution was to get a P3 Advanced instead, Lightbridge is soooo much better than WIFI video :-D

Hi P3A_Pilot, what did you do with your faulty P3S? Have you had any experience with DJI support? How would you evaluate them.

I don't need advanced model, I need my P3 Standard to perform as stated in the specifications (Range in CE mode should be 500m, and that's all I'm aiming for).

Hi P3A_Pilot, what did you do with your faulty P3S? Have you had any experience with DJI support?  ...

My experience with DJI support so far:

I wrote to the EU support 8 days ago (march 10th), since then I recieved 2 answers from them:
1. They asked me to relink the RC.
2. They asked me for my info to arrange RMA.
Havent heard from them since. Not really fast huh?

In the meantime I upgraded the app and the firmware. Relinked RC, recalibrated RC, recalibrated IMU. No improvement.

From what I read in this forum, some users send the drone back for repair, wait for a few weeks and then recieve an 'repaired' P3S with identical issues and no explanation what was done to repair the drone.

Forum moderators weren't much help either. I recieved 1 reply (from DJI-Ken in another Thread) asking me 2 questions, after answering them, there was no reply from him (them).

I don't envy them. So many user complaints to handle these days, but still... DJI should greatly improve users experience by speeding up the conversations related to service and support.

So here is my dilema:
- should I just except that the P3S doesn't have the range stated in specs and sell it or
- insist to get some answers and service?

Do you have the log file from the update to compare it with mine? log file

Can you search in the text for 'device not detected' and investigate if it shows in the same positions. My log shows it next to: [07 00], [11 00] and [12 00].
I'm trying to found out if that is causing the problem.

I don't have a P3S, but I read somewhere here that a P3S owner with similar issue resolved it by switching phone/tablet first to airplane mode, power on RC and aircraft, and then turn on wifi to connect.
Don't understand the logic in this, but this method solved the short range issue for him.

Thanks for trying to help, but I always fly in airplane mode (with only wifi connected to rc). Usually I kill all the apps before takeoff and turn off the background sync in settings. I use iphone 6.

That sounds odd. Usually, switching on airplane mode shuts down all functions that transmit, such as cellular, WIFi and Bluetooth. As cellular may be useful if you want to gets maps on your screen, you can leave it on, WiFi is necessary to connect to the RC unit, and Bluetooth really does not matter.

Hi P3A_Pilot, what did you do with your faulty P3S? Have you had any experience with DJI support?  ...

I returned it to the store as they have very generous return policy and they exchanged it for the P3 Advanced no questions asked.
Knowing quite a bit about WIFI I think the only way to increase the range is by upgrading the antennas with something like the Itelite DBS (That's what I would have bought if they hadn't returned it).
In general I think WIFI sucks as a connection option since it very much depends on the device that you use it with, even though I tried it with different devices most of which are brand new.

Interesting to see, that some of the forum moderators approve your mod and what you've done to the controller. Is your Warranty void?  Are you in FCC or CE mode? Where did you buy this mod how much did ya pay 4 it?

I bought a used P3S and updated before my first flight. So i can not say if there is an issue with a maybe broken connector in the RC.
But flying in beginner mode suddenly i got WEAK SIGNAL and RTH starts. Seconds later i got full signal?

I bought my P3S is six days ago and the radio range is short, maximum 100 meters without obstacles or interference , with pointed the right way antenna.

We are waiting for the Technical DJI make a new firmware FOR P3S the Faster What can because it has hundreds of dissatisfied buyers to the range of the radio signal.

Let us join all customers DJI and ask them to do a new firmware for the P3S . This will be the only way they make fast.

Also no improvements here still the same. That's bullshit. No solutions upto now. Money is gone for nothing. It is wiser to buy a toy quad like syma which will cost only 100 bucks.

range is a radio controller issue. the controller specify the output power for your location when you connect your phone to the controller. and imo it is not in use option at last 1.4.0060 firmware. also compatible app v2.7.0. can you explain how did you downgrade the bird?
