Thanks. My one concern about the common elevate and beeline back home, if you set it with CA you have no control of the bird at all..I understand that makes sense, if its tracking back it doesn't need the pilot mucking it all up.I believe that the conclusion for this feature is: it only kicks in when a signal is lost. It is an attempt by the AC to backtrack to the point where signal can be reconnected. It is not a selectable feature vs the common elevate and beeline back home. That said, the CA for return to home has to be set under the RTH advanced setting and you are correct that it would be ineffective in poor or no light.

This is supposed to automatically engage if the obstacle sensors are enabled. I attempted to reproduce this behavior yesterday (in a wide open location) and I couldn't do it. My Phantom returned straight back to the home point every time. I'm assuming there is some kind of built in logic that will only retrace the flight path when you lose the remote controller signal near obstacles. Unfortunately, DJI does not have documentation of this feature anywhere.What is the setting I want that will allow me to return home by tracing the route?

Yes.In your testing I am assuming you turned off the RC to force the RTH
Yes.
So long as you have connection to the drone you can cancel the RTH and retake control.Thanks.

How did you do the test with loss of TX connection? Did you turn off the TX? Or did you fly the drone out of LOS so it was an actual TX communication lost? In my testing, the backtrack only works with the latter. Turning off the TX initiated a normal RTH. It appears that the system is somehow "smart" enough to know that you simply turned off the TX and thus initiates a standard RTH.This is supposed to automatically engage if the obstacle sensors are enabled.

Yes, that seems to be the case. Here's an example of what happened when I caused the remote controller signal to drop by blocking it:backtrack only works with the latter. Turning off the TX initiated a normal RTH.
That's interesting. Without OA enabled it appears you could get into trouble and crash during return, since it doesn't actually follow the exact path. Seems like that could be a liability if you're out having a good time in sport mode and lose connection. Am I wrong?Yes, that seems to be the case.

The short straight line near the end of the flight is just due to missing data since the downlink was lost between those two points. The Phantom should have kept flying along the original path. As you can see though, the route back does not follow the path exactly. With obstacle avoidance enabled though, that shouldn't matter since the Phantom would correct itself if there were obstacles in its path.
Not to mention none of the sensors work at night.This is supposed to automatically engage if the obstacle sensors are enabled.

Sport mode in and of itself will not disable OA sensors during backtrack and RTH, it auto goes into P mode. I tested this. Disabling the OA sensors manually however, will disable OA during RTH and as msinger stated it will not backtrack at all with OA sensors disabled.That's interesting. Without OA enabled it appears you could get into trouble and crash during return, since it doesn't actually follow the exact path. Seems like that could be a liability if you're out having a good time in sport mode and lose connection. Am I wrong?
Read the entire manual. Ensure you fully understand all the modes, features, and how return to home works. Read it a few times if you have to. https://dl.djicdn.com/downloads/phantom_4_pro/Phantom+4+Pro+Pro+Plus+User+Manual+v1.0.pdfI'm new to the forum and just bought the p4 pro.
Is there anything specific I should know before flight?
