What Do I need for Competition?

Just curious, why get 2 ROAR-approved packs? You can get less weight, more power, and less wasted space out of a standard shrink-wrapped pack. In any case you will definitely want another battery.

Another good servo choice is the Airtronics 359 - 200oz./in. and 0.10sec., and they can be had for $110 easily. This is what is in my Jammin' X1-CRT.
However, I really like the feel of the Hitec 5955-TG (now 7955-TG). It's rated at 333oz./in. and 0.15sec., but is an INCREDIBLE servo. It throws the tires like they're nothing.

One list thing, stick with a steel spur. If your gear mesh changes for whatever reason, you WILL strip the Kyosho spur gear. And Mike's pinions will have no problem with a steel spur, so even if the mesh does change no harm will be done.
