Yes, we can change the binding, obviously ...
We can also put the TDC press on the weapon release of the stick if we want, or I don't know, the TDC slew on the throttle axis of the HOTAS.
We can do anything
Joke aside.
The point is not "change the binding and everything will be fine".
The point is : there is an option "realistic TDC slew" that allow to NOT keep the TDC pressed to slew MAVs.
It is great because for some HOTAS TDC (that aren't designed as the Hornet's one), doing so is a pain in the ass (x65 owner here, not pain in the ass but still not confortable)
We may also think that with such name, this option should also act for in fact all the Hornet command that request to keep the TDC Press (ex: AG radar EDIT: in EXP modes). But nope.
So either this option is intended only for MAVs (as it was at first), or it is intended for all "keep TDC Press" command.
In the first case, option should be clear about "mav only"
But the second option would be welcome
