Hi guys I bought a zipzap yellow mustang at my local radioshack and found out on this website that it wont go as fast as the bits so I bought me a bit on ebay and Im going to give my zipzap to my daughter, the bit I purchased is a bitchar-a and it comes with a 1.0 motor but it comes with a 2.2 motor also, Isn't the 1.0 motor the slowest you can get I was just wondering why they would sell them with the 1.0, so whats the difference between the bitchar-a and bitchar-g is it just the motor or is there other stuff thats different about them
Thanks Casper,
