there is an option in Settings/Control for Coordinated Turn (S-Mode) = Large (default) , Small, Disable.

I understand this is supposed to mix roll/yaw, i.e. you just roll (?) and it will automatically mix in some yaw  - correct?

but when I experimented with this it didn't really seem to do that much.
(its possible , when I tested there might have been higher winds at the altitude i was testing at - which might have masked it)

am I correct in saying, the intended operation is
Large - the drone automatically puts in a large amount of mix (so you could almost just use roll?))
Small - still adds a bit of mix, but not as much as large, encouraging you to start doing your own co-ordinated turns.
Disabled - drone does not mix, so for you have perform co-ordinated turns yourself.

does this mixing only happening, when you have a certain forward momentum?

so... kind of a training, as you get better you should go Large->Small->Disabled.    - correct?
I want to do the co-ordinated turns myself, to help prep myself for manual - so should disable - correct?

does N mode use any co-ordinated turns automatically - as this option is S mode only.



Is there a manual for the DJI FPV? last time I looked in the go fly apps, it said coming soon... are they online somewhere?


thanks for any enlightment you can provide

Essentially yes, it mixes in roll so the aircraft will co-ordinate the turns for you, if you are already proficient at co-ordinated turns you might not notice it.
