Help with Choosing Accelerometer for Arduino

hi guys

i am working on a little project and am trying to control my RC car with a motion sensing glove.

i want to get a glove, throw some accelerometers on it and hook it up to an Arduino.

a few questions.

First main thing i am looking for is fastest Response Time. On movement of the hand i would like it to respond as fast as possible to RC Car. Would an I2C be best for that? I am kind of new to programming and coding. Are those chips that much harder to get going than a analog one? i am definately willing to learn.. just wont to make sure it is nothing too crazy.

Second thing.. When it comes to range, I would like it to be pinpoint accurate and recognize the smallest of hand movement, so i am trying to stay with the shortest range possible. I am considering either 1.5g-6g. Just having some trouble tryin to figure out the max force i would get out of either 1) moving my hand as fast as possible, or 2) max force of wiggling my fingers as fast i can.

any input would be great

thanks

If you need to chain accelerometers on the same device, I2C is the best option: you can connect these together using only 2 wires.
You need tough a lot of calculation. I don't know if an Arduino can make it; depends of how many accelerometers and data you need to process for your project.
There are a lot of examples sketches out there, but these use only one accelerometer.
Regarding which one to use, the MMA line from Freescale has up to 8g scale (MMA8452). Beware that by incrementing the scale you lose resolution.
And you have a wide selection of breakout boards:
