To stop any confusion, you have Flight mode on you TX, Norm, ID1, and ID2, which changes the Head speed.
In the Ikon software you have Banks, where you can change the Flight characteristics.
Banks are just like real Banks, where you deposit money, but in this case, you are depositing modes of flight, ie Sport, 3D, Hardcore.
These modes have preset Dual rates and Expo. They also have the option to tick a box for Self Level and Gov mode.
Set AUX3 to the switch you want to use for changing your Bank.
I use the Gear switch, which in the switch set up menu is the MIX channel.
This only gives me two Bank options, not three, but I only need two.
Once you have done this, go into the Bank set up menu in the Ikon software.
When you move the TX switch you designated, it should highlight the selected box in Green.
Now you can set each Bank to your desired settings.
As I only have two, one is set to Hardcore 3D with GOV ticked.
The second POS is set to Hardcore 3D with GOV and Self level boxes ticked.
In this case, when I flick my gear switch on my DX8, all the setting are the same, except Self Level is activated.
I hope this clears some things up.
Let me know if anyone else has a question.
PS. Can't get into my Ikon software at the moment. Just did a full clean install on my Mac, and don't have that Windows Crap on there at the moment
