Wow, fantastic pictures proosen. Those will help a LOT.
I have all three of the new AMT monsters, and these things have more flash and mis-aligned parts than any of their 40+ year old re-releases I have (Maybe a half-dozen).
I think with some smaller planetaries (The giant hubs insides the wheels are a gear-reduction unit which allows for a smaller axle, as opposed to the giant military axles used 20 years ago) they would look a lot better. I'm going to cast some from the older AMT Bigfoot kits to use with all three of these.
