I just got a Nitro rustler 2 weeks ago. It runs fantastic and I am in love with it, I treat it like a son. I am very low on money at the moment, and want a car that can take more, climb more, and faster.

This is why, I am making my own car!
I plan on buying seperate everything, putting it together and making the car thats just right, but I need some opinions on what parts I should get too. I am planning on using either the HPI-Nitro Star S-25, or the O.S .21 RG-X as the engine. Both very powerful, great speed, and great reviews. I want this to be an offroad truck, a Stadium Truck/Monster truck. Kind of like the Stadium Maxx, except faster and better. Please help me out with this. First I need to know what kind of the following I need. Im starting out with the simpler stuff!

Chassis:

Engine:

PLEASE OFFER SUGGESTIONS OF ANY QUALITY PART YOU CAN THINK OF THAT WOULD BE GOOD FOR THIS CAR!
