Looking for 1/48 space shuttle model

Hi guys :D I am looking for a good 1/48 space shuttle model to scale up to 1/24 , I know thorsten is building one now but I think he is not done with it yet and I couldn't find the plans on the yahoo space paper modelers group. I have found a few links to 1/48 space shuttle models on this forum but those links are broken, if you know of or have the plans to the model, please let me know
Thanks :D
