Sounds like the main motor bit the dust, Unplug the tail motor and spin it up , do the same with main motor and you'll see which one is causing the problem.
Hmmm , also check to make sure that all the hardware is still holding the head and main gear on properly. But from what you describe, its gonna be a motor.... and yes they are junk, I've had these little brushed motors go bad in 2 flights.
