Well, I took that monster that Betty-k sent me, through in the biff. Let me tell you, IT”S MAD! This thing really is a monster. It s extremely fast. I recomend the biff to anyone. It s extremely easy to install when compared to the original fet modding, of course ph2t does all the hard stuff for us. I also threw in a 4.2 pro from perfection and replaced the 1/4aaa with 1/3aaa 200mah nimh batts. Thanx to betty-k s hard work it came with a on-off switch to protect the nimh s from draining all the way. Now because of betty-k and ph2t, I ve got this car that s simply amazing. I love the way it handles and I love the speed. I also replaced the pcb with a LXX 27mhz a booster pcb. The performance unboosted is better than most and with the boost on, nothing stops it. I think I m going to use this car to chase small animals around.:evil:
