I may have done a stupid thing. I bought a used Phantom 4 Pro, supposedly working perfectly and I seem to have bought a lemon.
All seems fine on the ground but when the thing gets in the air it seems to have a a mind of its own. I get multiple compass errors, speed errors, yaw errors and it’s near impossible to control.
Sorry about the poor formatting. I’ve aligned the IMU, I’d calibrate the compass if I could find the option.
Having resisted the temptation to take a very large hammer to it I’m open to suggestions. No chance of getting my money back on it and I’m reluctant to put good money after bad by sending it to DJI.
Any suggestions folks? Or is anyone interested in buying a faulty Obsidian Phantom 4 Pro with a ton of extras
Have you uploaded your flight logs to air data if you have would you mind sending me the link and I would be more than happy to help try and fix this problem for you, and obviously discuss the issues that you are having in more detail.
Okay that’s fine however I myself won’t be able to look at it straight away as I am currently away on holiday anyway however I will respond to you ASAP and we can try and get it resolved!
Tap the “Calibrate” button in the “Aircraft Status” section of DJI GO. If the “Calibrate” button does not appear there, then you can calibrate the compass from the “Advanced Settings” section of DJI GO.
Well I am both very happy and feel very stupid at the same time! The main problem seems to have been the compass calibration and once I found out how to do it, we’re looking good.
I cannot believed that I overlooked this, I know I’m an idiot. Many thanks for all the suggestions and especially to @alexmciver who helped me via PMs
You are more than welcome and I have now checked your flight logs and all seems to be in working order however I do recommend that from now on you do a Manual takeoff rather than an assisted auto takeoff because if something happens during takeoff you can stop it quicker than you can if the motors were in auto
You are very welcome I’m glad that I was able to help you get it resolved so that you didn’t have to put a hammer to it and now maybe you should add it to your list of drones in this forum?
The reason why I said that is because I was told that sometimes people have done autoland and take off and it doesn’t give enough power to the motors and sometimes drones have tipped over
