Our Tiger 1 kit is a good kit to start with. It is a metal edition Tiger 1 early version tank and comes with no transmitter or motherboard so you can add your own electronics system. It does come with all the rest of the components needed to build the tank and even comes with steel gearboxes. You also get some good USA support if you need too
You can view the nice HD manual here if you wish:

I worked hard on that manual myself so you let me know if you have any questions.
