I have a problme with some weapons. Some of the weapons shot were the ship it going to move too. It does not shot the ship itself....I hate that...if you could disable that it be better...i would get more kills...

All of the weapons do that. The deficiencies in the aimbot are well known. You can 'disable' it simply by not targeting the thing you are shooting at, though I think you will find that that doesn't come close to making things any easier if you are new (try it sometime). Aiming without the aimbot is harder than you think, and there are probably even some tricks to the aimbot itself you haven't yet discovered (which edge of the aimbot you lead seems to play a role in accuracy for instance). Still, it is widely agreed that you need to be able to put targeting in a manual mode and/or that the aimbots prediction algorithm needs to improve (it doesn't do well at all for a target that's roll+strafing for instance).

/set autoaim 0
Disables the auto aim.

EDIT:
you can also do the following:

Discription: When 'key' is held down auto aim is turned off. Switch the 0 and 1 if you want auto aim to be on when 'key' is held down.
/alias +aim "set autoaim 0"
/alias -aim "set autoaim 1"
/bind 'key' +aim

Discription: Hit 'key' to swich whether or not auto aim is on.
/alias aim1 "set autoaim 0; bind 'key' aim2; echo 'auto aim OFF'"
/alias aim2 "set autoaim 1; bind 'key' aim1; echo 'auto aim ON'"
/bind 'key' aim1
