Flight mode "attitude" Turnigy TGY i6 for quadcopter

Hi, I'm using the Turnigy TGY i6 transmitter for my quadcopter but I have a question about flight modes.
I want my quadcopter to auto-level once I release the right stick, and I've read that this can be made using "Attitude" flight mode. But I only found Normal and sport flight modes. Then, searching, I read that this mode can be configured changing the pitch curve so I changed the type of my model to "Helicopter Variable pitch" and set the pitch curve to 50% on all its values but the quad doesn't seem to auto-level.

Any idea on what I can do?

Thank you in advance.

I don't have a flight controller some there's some guess work below but it may help...

The normal and sport mode on the i6 TX have nothing to do with flight controller modes. They are associated with the programmable rates setting on the TX where normal is low rates and sport is high rates. Rates are a TX feature that reduce the maximum throw of the various controls surfaces, ail, elv and rud. On the i6 these are associated with particular channels so normal/sport modes only affect those channels

As I understand it, flight controller modes are particular programs that run on the flight controller that exhibit particular flight behaviour. They are typically selected with a particular servo position signal on a particular channel. On the i6 you might associated CH 5 (or CH 6) with the three position switch giving the ability to switch CH 5 between servo positions, -100, 0, +100. Presumably you can configure the flight controller to respond to CH 5 and switch between 3 different flight modes using this.

To select a particular flight controller mode you need to associated it with one of the positions of the the three position switch on CH 5 which will send either -100, 0 or +100

Possibly you may need an intermediate servo position to select the mode you want, say -50%. So the question is how to get the three position switch to send -50% rather than -100%

I don't have my i6 available to try it but probably you can use a mix to do this using the three position switch as the source and setting the -% it sends on CH 5

You might be able to use the pitch curve function since possibly you can set the the servo position for any particular position of the associated switch but since it requires you to use heli mode it may add some unnecessary complexity

Probably the mode you describe is one where the central region of the right stick motion say -10 to +10 of the ail direction and -10 to +10 of the elv direction are detected as indicating that level flight is desired and the flight controller automatically levels the multi rotor. Normally an airplane would just continue in the current direction if that stick is centred. My guess is that once the mode is selected then this behavior is automatic.

Also you might find this video useful. He uses a heli model though it is not clear why. I don't think its necessary. And he uses servo endpoints and subtrim on CH 5 to set the servo position for the 3 position switch apparently to switch modes. He also use a pot on CH6 for something. Presumably his flight controller responds to those two channels to set modes (via CH5) and vary some parameter (via Ch6) Which channel is used for which will depend how you nook up your flight controller to you receiver

Ok I'll make my tests and tell you something soon thank yoi for your reply.

PD: tests will have to wait as I crashed my quad today and I'm waiting for new props LOL.
