What would I set my warning voltage to on a DX7S when I am using 6S 22.2V 5000MAH Packs that control everything in my Trex-550. I do not use a separate RX battery pack and I need enough time to be able to land. I do not know how to perform auto rotations as of yet.

I use 20.5v, seems to work well for 80% pack discharge. This is of course warning under load. Once it starts to warn, then I know my timer is about to beep too.

Thank you. I just went out and tried 20.5 and it worked very well. It is interesting to see the voltage dropping and rising during flight. With the 20.5 setting I am getting about 12 minutes of basic flight on my 550 which is very good.

resting voltage should be around 22.3-22.4v at end flight, considering 80% rule. Good to hear it's working for you.
