stick it in the freezer it will shrink the roll pin or get some 134a and blast it with that
aluminum shrinks faster than steel. The best thing would be to heat it up hoping the aluminum would release the pin, but because the pin is made out of, what I'm guessing, is spring steel, it will just expand when the aluminum does. And why are we even talking about this anyway, you were the first one to post that you didn't want this engine in this heli?
