I've go the charger, batteries, motor, servo, and ESC. I'll get a new TX and RX as well. Other than that, I just have a stock micro-T. I don't want to put aluminum anywhere that it is not necessary. I want to know what the bare minimum mods I need to make to handle the power. I wouldn't mind another chassis if it allows better/easier placement of the electronics and is cheap enough.

Ball bearings, new tires and wheels, ..... I'm guessing suspension, since the stock rear is so soft it will likely drag the ground constantly. What else?
