Volantex Xpilot AX601 6-Axis Flight Stabilizer

all ok but i can’t work this function: * Two different level switch-able* pls help me how working this . the manual is not good to make it wotk

I am sorry to give a negative response to the product, extensive bench testing proved the units, I purchased two, to be unreliable. Generally the rudder would not return to centre, it would take up random endpoints. Overall I would not trust it in a rubber ducky in bath, certainly will not risk a pane for tests. I can’t express my concern at the lack of instructions, abysmal is the only word I can use.
