If you were thinking of getting Acu-stion's resin wing for the new Tamiya NSX, just a word of warning - its pretty crude and inaccurate, and I don't think worth the $15.
It is too thick, doesn't have the right profile shape, the edges are too round, and its missing some elements. See attached photos.
Here is Acu-stion's response to my concerns: "It has understood. You must correct it. Please make it by yourself. After all, the enjoyment increases because it is a model."
While I don't mind doing some scratch building, when I pay $15 for a small part, nearly half the price of the kit, I don't expect to have to correct the part.
