Hi,
I recently purchased a Phantom 4 and totally love it. I have read all tutorials and take the best care possible of my new beloved drone! Having said that after only a few weeks the drone has stopped flying straight forwards. I've checked flight logs as advised and I am only pushing forward on the controler but it banks to the right and is really effecting my filming. It is making it nearly impossible to get a shot along a path or river where I have to keep things straight!

I have done countless cold IMU calibrations, gimble calibrations always correctly calibrate the compass before flying etc etc.. Been trying to solve for ages now can anyone suggest anything that might help or do I really have to return this to DJI?

Thanks in advance..

deanturner, If the drone can't fly straight, I'd recommend you to try the remote controller calibration and see if it happens again.

hi
have you had any luck??


I emailed DJI yesterday:


Hi I was wondering if you have come across this before? The drone was obtained in September 2016, so is still within warranty. My phantom flies off to the left when the stick is pushed forward. Over 50m it can veer off to the left by 5-10m, so quite a considerable diagonal "drift". I'm flying a Phantom 4 (WM330A) with 8" Samsung Galaxy Tab S2 running Android and DJI Go 4 app. I have ensured I have: -the latest firmware updates -calibrated IMU -calibrated gimbal -calibrated controller -calibrated compass -inspected motors visually ok -inspected propellers visually ok -flying in GPS mode with strong signal on a fine clear day -fully charged batteries in the quad, in the controller and the tablet. I have flown the quad approx 12-15 times, never crashed it, safe landing every time. always cased up when transported, never been bashed about. I looked at a few videos online, some people say its compass or the controller that needs calibrating, but I've done all that.... I thought it might be 1 motor causing it to deviate off course, but then it wouldn't hold position at all if one motor was dodgy. Then I came across another video saying that the NAZA M doesn't allow for magnetic declination and learns as you fly, so you have to fly for 8-10 minutes while it's learning the compass deviation and eventually it straightens itself out, but it does that on every flight! So that's half your battery life/flying time gone just sorting itself out on every single flight... Surely an issue as serious as that - DJI would be aware of that and a simple firmware update would allow adjustments for magnetic declination depending on your GPS location? I've got a £1200 device that I'm hesitant to fly because of the way it behaves and I've made all attempts to make sure that everything is updated and calibrated and I'm flying safely..... Am I missing something here? Any tips/advice/recommendation? Thanks



the replied back saying I need to send it in....

I also emailed dronedoctor.co.uk as they're listed on the DJI site as  the primary UK service centre,
they said they don't do warranty work and i would need to send it in, they would diagnose it and quote me for repair...

very frustrating

hi
have you had any luck??

Just to clarify, have you also tried resetting the unit to factory defaults in the Assistant 2 software? What kind of areas are you flying in? Is it always to the left, or does the direction change? Can you recall about how many satellites you have when this happens?

If you are taking your time to reply at least inform him how to do a Controller Calibration or where he can find the information to do it.

Clearly he is new at this and he turned to this forum for help....just saying
