I've experienced screen flashes and temporary blackouts while in flight using an iPad air that was 2-3 years old. I switched to an iPhone 7+ and has been rock solid for 20-30 flights now. No other changes. Added benefit is the screen is more visible in sunlight. Downside is the smaller...

Awesome shots. To add to this, pointing out that real estate photographers will often be obligated to fly over water to get the money shots. This shot was necessary to show where the home is situated relative to the nearby beach.

Searching the internet for cases that have been prosecuted and am not finding any that are related to the "flying for pay" aspect of the licensing requirement. For example, a recent New York Post article...

Thanks George. I have experienced on and off RC disconnects with my P4A. I’ve also had mixed results on range. I finally simply compared the noise levels being reported in the DJI GO 4 app on the IMAGE TRANSMISSION SETTINGS screen when my iPad was in and out of airplane mode. The iPad has no...

One thing to consider is iPhone screen provides better image than iPads in sunlight glare. That’s a trade off of size vs image readability.

Made an interesting observation today regarding the wifi state of the ipad I was using as the control device. Got "disconnected" repeatedly. Changed ipad to airplane mode and connection was stable. Checked "Image Transmission Settings" and found noise levels were evident on several channels...

Hello wa5tef. I am waiting for a set of carbon-fiber props and noted your comment about some being out of balance. How do you test for that ? Thanks!

Thanks again BudWalker. There must be 1000's of P4's out there. Gotta wonder how many are experiencing this. Thanks to all who contributed their ideas and experience to this thread.

Thank you again for the further analysis. To my knowledge, the P4 has never been dropped or banged. It's a pampered drone. Assuming the calibration fixed the problem, I'm now considering what best practice is. Calibrate before every flight ? Every nth flight ? Waiting until compass/yaw/gps...

Sure...just posted. FLY068 was the last actual flight before FLY071. FLY011 is the oldest actual flight I have.

There is no tracker on this aircraft. Thanks again for the analysis! I owe you a beer or two.

OK, got some new results. See data logs FLY081.DAT and FLY082.DAT at the link below. P4A data files - Google Drive FLY081 was a short 3:34 min flight after calibrating IMUs only. I terminated the flight after receiving "compass error", and "weak GPS signal" messages at 1:33 min. I also got...

I presume this means we're not really expecting the IMU calibration will fix the root cause, but that it's still a good idea to do that and verify with a test flight to take it off the table. Am I reading you guys correctly?

Thank you Budwalker. That will be my next step. I'll then repeat the safe low level test flight and report back.
