Very nice. I particularly like the first & the Unimog.
What chassis do you use?
Is there a standard modestly priced introductory chassis that is repairable & for which bits are likely to be available for some time?
The first one is a GMade Bom, good trail truck, verdict is still out on it raw crawling capability.
The next 2 are Teaxxas TRX4s, one sport and one with 2 speed transmission and unlockable diffs.
The Unimog is an Axial SCX 10 ii, but on the Mog the wheelbase is considerably shortened.
The are all kit builds, and all but the Mog have custom bodies, the Mog just has a custom paint job, and a few custom accessories.
I have a few others, a high end Vanquish VS4-10 Ultra, and a custom build on Element Enduro running gear and a cnc cut chassis.
If I was looking today, for a kit to get started with, I'd either go SCX10 ii, or Element Enduro builders kit.
