Hi!
I've started some time ago a project with my kids. I promised to build a tractor (a big one) that has 4 wheel steering as well as crab steering...
Here it is afte 4 XL motors, 2 servos, a pneumatic pump and I don't know how many times I have assembled and disassembled tyres, cabin, hodd, fenders and so on and so on.
Still some work to do (hitch, red rims ...):
