Will Riggen track and Revelle track intermingle? Can you attatch the two together, I asked a few friends and they "Thought" so, I look at the blurry pictures on eBay and it looks like they might, but I wanted to make sure, so if anybody knows for sure they can be used together that would be great, Thanks.

Yes, the track is compatible and made from the same molds. Revell track is gray and Riggen track is black. From what I hear, the older Revell track is a little better quality than the newer Riggen track.

I bought a Riggen set from NCP Hobbies awile ago, it came with grey track. Did they use revelle track in the pro-am gtp sets? Anyway thanks for the answer, I was leaning that way, thanks for the push!

Not sure. I was under the impression that all the Riggen track was black but maybe one of the first runs was grey or the set could have come with NOS Revell track.

Best regards,
