the firestorm is already in stock you can buy them off ebay if you want or towerhobbies.com... but i wouldnt go with a 2wd they dont have very much control i would go with the mt2 18ss cause it has the same size engine and its 4x4 truck... are you new to nitro rc

here is a video of the firestorm, but i am told that it isnt stock....it goes to show that it cant handle very much power while still being controllable
