How to freeze axis ?

[Reax178]

Hello, i would like to know how to <<freeze>> my axis (X and Y) at their current position with a button, and get the axis working again by pressing another time the same button ?
I found something very similar to this viewtopic.php?f=27&t=3653
But this resets the axis at the default position, i want it to stay where it was until i pressed the button, to use it like an altitude / heading hold in aircrafts that have limited trimming and autopilot possibilities, like with most warbirds.
Thanks for your help !
