Is the center part removable? The big spur part looks like standard issue, but the center looks like its pressed in, or just a misaligned mold? I have the thorp under and over drive sets, and they dont look like that.

Yes, the inner part is steel and pressfitted.

How does it differ from the special center gear from the Pro XL and others? I have one somewhere but can't get to it to see, but here's one that Monogram has listed on ebay

cherish that gear, eBay seems to think they are fairly precious!

I do - it rests on a Ultima Pro V1 (aluminum chassis) Apparently it sits as it came from the factory.
Hardened final pinion and special center gear.

I got these two in a package deal. The Mid looks like it was only ran a few times...it seems to be all stock with the exception of Andys front arms and a Losi Xcellerator body. The Ultima, ran a little more but its still in good shape and all stock....

Last post

IIRC correctly the Turbo was slightly thicker material, and was bronze color / hard anodized.
