dont worry, answering questions is what we're here for ^___^. It looks like you may have fried you motor... when you push too much voltage/current through a motor, they wear out faster. try buying a new motor, or borrowing one from a friend. Also, try reseating the battery, or even a new battery. If all this doesnt work, peak charge the battery, or charge it 4 times in a row, and see if that helps.
i hope you get it fixed
oh yeah... and bits can compare, and even beat digi-Qs, with a lot of moding... i believe the new 4.2 motors are pretty quick, and also, with a dual cell, or even triple, bits are gonna tear ass
