If you insist on using Lipo's, may as well go with the Losi (I call them Sportworks now.lol). The lighter battery (over NiMh, Orions 3200 pack is almost 7 ounces lighter) will give fits on chassis ballance. The losi, not so bad because of everything being located in the center of the chassis (w/ exception of esc and reciever). Unless you have the skills of National competition, you wont need the Spread Spectrum (honestly, most all the people that buy something like that, dont need it, and wont even notice the difference, but it is the latest and greatest, so people think that they Have to have it). I have had a lot of sedans in my time (still have several) and the 007 is by far the best (IMHO). I have a TC5 now (duly impresed) and I still run a T2 ('06)for rubber tire racing. Oh, the 3200 packs fit the '007 with a little modification to the right rear bulk head.
