you don't have to worry about what motor it comes with. i would get the one that comes with 1.0 because you can run your car on table top if you have 1.0 2.2 or higher is kinda fast for table. unless you have a big table. i can run my car with 1.0 on my desk thats about 3 foot by 2 foot. oh and you can always buy faster motors. I have NEVER seen anybody sell the 1.0 motor so if you want it you should get a set that has it. thats what i did.

Digi Q are faster stock. but they don't have any hop ups. and Digi Q turn by changing the speed of the rear wheels. like a tank. the front wheels on a Q don't turn.
so its really up to your personal preferrence. if you want to upgrade, go with a Bit Char-G. if you want to keep it stock and do some donuts and stuff, get a Q. Q also cost more so you might want to take that into consideration. I was originally gonna get a Q but saw the inital price of $60 on ebay vs$30+ for a bit char-g. So I went with bit Char-G. I like the front wheel steering better. but i've never tried a Q before.
