They're not too bad, if you can solder good. 12 to 14 cells will give you a little faster than the titans for the given cell counts, Lipo's are the deal for high-powered setups, but if you don't know much about them, do a lot of reading beforegetting them, Knowledge is power. For gearing, try a 18 to 20/66 (32 pitch) or 16/51 Mod-1 (recomendation: Save your money and buy a strobe and go Mod-1) not even the robinson slipper can hold the power of the XL motors, it did ok on NIMH cells, but not on LIPO.

The duratrax ICE is a good charger and can charge you're LIPO's when you get there, don't forget the balancer.
