You have to change the view angle in Lock On!
If you use Modman you can download the.......... but you have Lock On 1.0 so what you can do is adjust the server file!
Go to directory \Ubisoft\Eagle Dynamics\Lock On\Config\View and open the Server.LUA in NotePad (BTW make sure that you make a backup of this file)
Find these lines
-- Camera angle limits {horizontal angle max, vertical angle min, vertical angle max}
CameraAngleLimits = {}
CameraAngleLimits[PlaneIndex.iSu_27] = {160, -76, 90}
CameraAngleLimits[PlaneIndex.iSu_33] = {160, -79, 110}
CameraAngleLimits[PlaneIndex.iSu_25] = {109, -70, 105}
CameraAngleLimits[PlaneIndex.iSu_39] = {116, -85, 110}
CameraAngleLimits[PlaneIndex.iMiG_29] = {160, -80, 110}
CameraAngleLimits[PlaneIndex.iMiG_29K] = {140.0, -65.0, 90.0}
CameraAngleLimits[PlaneIndex.iA_10] = {160, -72, 110}
CameraAngleLimits[PlaneIndex.iF_15] = {160, -81, 110}
and replace this with yours.
I have to say that I'm not sure that this is the same because i using 1.12 and you 1.0 but thats why you have to make a backup.
