Q. The model is ... Cobra 3 channel mini helicopter X107 with gyro. I know that the top blades are spinning faster causeing the issue. But how do i fix it?
Answer
the top blade always spins faster than the bottom one (same with big lama 4ch co-axial helicopter, had one... and always broke the upper blade) so here's what you'll do:
if the helicopter spins in a crazy way to watever side, then:
go to the receiver, next to it there is a mixer, like 2 knobs that you can put a screw on it and move it, look carefully and move the "Proportion" knob left or right until the helicopter stops spinning.
if it spins slowly then:
look your transmitter, it has like little knobs that you can adjust left or right, they're called "Trim tabs" move the trim tab from your rudder left or right until the helicopter is steady.
if that's not the problem then it might be time to replace the motor of the upper blade.
if that's not the problem, go to www.rcgroups.com create an accout, post this question there and folks with waaay more experience than me will help you out.
Happy New Year!

Answer
They are the drive gears to connect the motor to the rotor
The small pinion gears are connected to the motor shaft and the large main gears to the helicopter blade rotor shaft like this:

IF you need to replace them, this is what they will look like:
