How to set "move forward" to "zoom view" in freetrack?

Hi,all.

I use freetrack in DCS:BS.I enable 4 DOF:pitch,yaw,X and Z.Now the Z is move head forward and backward.As the PC monitor is so small,I want to assign Z axis to "zoom view".

blow is \DCS_Black Shark\Config\Input\Aircrafts\ka-50\headtracker\default.lua

-- headtracker axes

{combos = {{key = 'HEADTRACKER_PITCH'}}, action = iCommandViewVerticalAbs, name = 'Absolute Camera Vertical View'},

{combos = {{key = 'HEADTRACKER_YAW'}}, action = iCommandViewHorizontalAbs, name = 'Absolute Camera Horizontal View'},

{combos = {{key = 'HEADTRACKER_X'}}, action = iCommandViewHorTransAbs, name = 'Absolute Horizontal Shift Camera View'},

{combos = {{key = 'HEADTRACKER_Y'}}, action = iCommandViewVertTransAbs, name = 'Absolute Vertical Shift Camera View'},

{combos = {{key = 'HEADTRACKER_Z'}}, action = iCommandViewLongitudeTransAbs, name = 'Absolute Longitude Shift Camera View'},

{combos = {{key = 'HEADTRACKER_ROLL'}}, action = iCommandViewRollAbs, name = 'Absolute Roll Shift Camera View'},

{combos = nil, action = iCommandViewZoomAbs, name = 'Zoom View'},

I edit some word,but the program has error when it load.How to do?

When I look down in KA50's cockpit,I can't zoom view by freetrack.

I want to assign Z axis to "zoom view" instead of "Absolute Longitude Shift Camera View".

This is easily done.. You just need to figure out the axis name that freetrack is using.. Freetrack will use a parallel port joystick emulator to apply the freetrack inputs.. In my set up "moving head forward/backward" which I also like to use as the in-cockpit zoom is labeled "Joy RX" in the BS options menu.

Edit: You should not need to edit any files... all is done in the BS options menu..

Thanks a lot.

I have success.I enter the menu:option--axis commands--zoom view,add "TRACKIR Z" and clear the old config.
