Thanks to its extraordinary features, the Savage Flux HP is the best choice for drivers looking for a ready-to-drive monster truck with maximum driving pleasure. Driven by the generous Flux Tork 2200 motor (2.7 KW peak power i.e. 3.7 HP) & two battery packs, you'll perform wheelies & unbelievable jumps to your heart's content with just a flick of your finger! The Flux Blur regulator can control the highest power, so that you can use up to 16 Ni MH cells (2 x 6-8 cells) or 2 Li Po packs (2 x 2S 7.4V or 2 x 3S 11.1V). This unbelievable power overshadows almost every combustion truck!
