motor cooling system on the xx4 worlds edition

[rcracer]

hi all,

im just wonderin has anyone had to cut/file down the fins on the motor cooling fins on the fastrax motor cooling system to fit on the motor properly on the Losi XX4, im using a lower motor mount ive tried the normal one but it still catches on the chassie and its not fully covering the motor to take it to the full cooling temp which i require, the last thing i want to do is take the fins off or ruin it, its my sons and hes not had it long lol
