First, I am total newbie to Oolite - and to this community - although I used to play Elite back in 80s with ZX spectrum.. What a great game it was, and thanks to the community, still is

I just installed OXP called Griffs normal mapped all-in-1 in order to update those default ship textures and succumb into some extra immersion. Everything went okay, but my (the player's) cobra is still one of old model. Is there anyway to make player's (default) Cobra to look one of those awesome NPC cobra's that cut the space? I know I can buy a new one from station (tried that), but it takes so much of my hard earned credits, so I decided to turn onto you and check if there is another way...
And if there is, I'd appreciate very detailed instructions, because I am not hacker, just an occasional gamer.
Thanks in advance.

PS. I tried to search for instructions, but couldn't find anything very useful. Maybe I didn't have right key words.
