So there is an Outfitting There? If so sell everything, or D class it. Make it light and an A3 FSD will get you out of the pooh!
Already mentioned in past posts, I've checked and even with the lightest fit possible he can't get more than 6,82ly with a A3 FSD.. :/
One other brutal way out (you'll lose the Cobra, though) would be to destroy the cobra and accept the Sidey as replacememt.
Would be the very last option actually.. x)
