These sets have very complicated gearboxes. The orange Extreme 4x4 is a remote control car and the Land Rover will move from high range to low range 4x4 and through the gears from neutral. It was enjoyable to build.

You're right, it's not cheap, but it's enjoyable, relaxing to build, so I'm happy to spend a little now and then. It's time for these to come apart though, and I think I'll make something else out of each one. I've done posts on most of my builds so will do the same. I hope you manage to get your set, maybe you'll do a post here in this community about it.
