Curval...
in my x45 (i know not x52) the rotaries work properly in game, but the joystick wave graph does not show movement for them
just in case try this. make sure in the programming software they are assigned as analog.
delete the jstick.cfg in the AH settings folder.
start AH, and before anything calibrate the stick, move all axis especially the rotaries.
goto select joystick and assign axis, when you get the the rotaries the numbers should go up and down if you move them.
try in game if the adjust trim with all auto pilots off.
like i said my dont show as moving on the wave graph but work just fine.
lastly, if you had an x45 you probably know that the rotary generally used as elevator trim is backwards in AH and you have to invert the axis in the js settings of AH
