Blade Inductrix binding?

I have a devo F7 transmitter and a blade inductrix FPV (not pro) the little yellow canopy one.

Flies great. Problem is, I have no clue how to bind GEAR0 and GEAR1 to change it from self leveling to acro modes

Anyone have any idea what the blade will recognize as those functions? is it VERT1? Please help.

Hi , I need a little help here .
I just bought a bladeinductrix and I'm trying to bind it with my Devo f7 but it won't bind.
Thankyou.
