Activetrack reverse flying and P mode

[inkytog]

Hi all,
Just a quick one. I thought there was a reverse sensor on the p4p - so if I enable active track backwards flying - there are no sensors in reverse?

Also. if I have the 'Multiple flight modes' switch in the app to 'off' (so I don't knock the switch accidentally on the RC) does the Drone still sit in P mode with all the sensors on or do I have to have this flight modes switch on and then P mode becomes active.

Thanks!
