The primary problem is that it's not just tilting wheels. Everyone reading this will know that, of course. The old Aoshima model kit solved the problem incredibly elegantly with a sliding mechanism that moved all the wheels out from the body while tilting them at the same time, in the same way that they worked in the movie. The problem comes in when HT have to do that same thing. The Delorean is *heavy*. So it would have to have a stand and a remote for the wheels, and making that mechanism work, plus the inevitable returns they would get when some didn't work... This mechanism works for a 1/24 model kit, but the Hot Toys wouldn't be able to sit on it's wheels with a mechanism like that. It's too heavy.
