I have seen this build thread awhile back, and if i remember right one of our members here posted this sometime ago on another site before this very cool site.
He did a replica in 1/14 of the Rubber Duck Mack from Convoy. Sorry the thread is in Japanese, but it is just so cool. Wish i had this kind of talent
