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:

Ps> I got the hair out of the taill rudder and it still does the same thing and i dont want to spend more money on another if i dont have to so can anyone plez help me. Thanx



Answer
Which heli is it? That will help us help you.

If it is one of the bottom end 2 channel helis like the Picco Z or the Havoc, then besides hair, there are 2 more things that will cause this.
1. The tail blade has a crack in it. It inly takes a very small crack to make the tail less effective and it spins. Most models come with a replacement tail blade in the package.
2. You have a defective heli. Of the 30 or so models that I and my fellow RC club member purchased, fully 50% failed in the way you describe, out of the box.

You can also ask on the dedicated RC heli forums:
