the dude says the ion batteries are a must, and the FET's are needed for the upgraded motor. For now I was just thinking of getting the car, motor, electronics package(i beleive this takes car of all electrical stuff needed for upgraded motor), and wide bearing set(only $10 more than metal set offered from radioshack). So that is $226.90 total befor taxes and shipping, and I'll have some christmas money left over.
I would not be buying this if I wasn't getting like $250-300 for christmas and the 21.5 AWR swaybar with adjustable endlinks.
