First off, welcome! You'll find the best group of individuals here for such a small niche hobby. What did you get yourself into.....be prepared to buy many more tanks. Also let us know where you are in the world. Could help with advice as someone maybe in your area to run with or help wrench when it comes to that. For the actual tank depends on what version you ordered. May want to upgrade gearboxes, electronics to hobby grade, motors, etc. Get it, run it in some dirt and see how you feel before you get into any of this though.
