There is no big deal.
My point is that there is nothing wrong with the Mini-X for sale in the US right now. The Xj is just the same car with a modified tie rod. People should not wait around for some new Xj version because it is the same car plus some ball links.
If you want the tie rod hop-up just go to your LHS and buy some Dubro ball links and some threaded rods and DIY.
The Mini-X is arguably the most advanced 1/24 RC car available. If you want it to progress you need to buy one and experiment with it and share your ideas, not wait around till a new version comes along.
The Xj is NOT a new version. If I'm wrong Usagi, I'll buy us both one!
