Your throttle controls how fast you move around in CMEye. Use a very low throttle setting at first. If you don't you can go half way across the map in a flash.
From the KOTH Arena Message:
There are a few ways of course but it is easier to set up
a 'Mode 3' and use your joystick buttons and throttle.
1) Go into Options > Controls > Map Controlers
2) Open the Mode Selection menu, select 'Mode 3'
3) Hit the 'Copy Mode 1' button
4) Select Button 0, set to 'View CM Eye Move Forward'
5) Select Button 1, set to 'View CM Eye Move Backward'
6) Select Button 2, set to 'View CM Eye Move Map'(optional)
7) Go to 'Map Keys' and set an available key to
select Mode 3.
8) Its a good idea to also map a key for Mode 1.
I personally set it to the * on the keypad.
However, there are other keys you can use.
CM Eye should now work.
Hit F5 from the Tower, then your key to enter Mode 3.
Joystick buttons 0, 1 and 2 will move you around in CM Eye.
Your throttle controls how fast you move.
