I got a u-Control Phantom RC Helicopter today from Brookstone. At first when I flew it I had no problems. I crashed it a couple times but it still worked fine. Later, I flew it again and it goes up but only in circles! It doesn’t circle around or anything, it TWIRLS and won’t go forward. I replaced all the blades but the problem remains consistent. What should I do?
Note: The left and right stabilizers don’t help either.

Just like the other answer that was posted its your tail rotor but if not that then check your trim.
and if all is working then if your heli is equipped with a gyro then its a gyro failure.

Hi :
Let review the basic is how a helicopter fly
first off the bat you got a main Rotor which spin around and it lift the helicopter off the ground and soon as the landing gear leave the ground Your Helicopter encounter a force that want to spin the helicopter around in a circle in the opposite spin of the main rotor ( or twirl as you call it really called torque) . A man named Igor Sikorsky came up with the idea of attaching a tail rotor to counter act this force. the Helicopter is one of the most difficult aircraft to fly even for seasoned pilots. you have to constantly keep adjusting the controls just to fly it forward or take off . when you increase the main rotor speed you need to increase the tail rotor speed a bit to compensate for the counter force the main rotor make in torque
after seeing what this helicopter look like
check the two main rotor and see it they are spining in opposite direction of each other if they do then there fine if it got a tail rotor on it check which way the air flow from it is going . It must in the direction of the main rotor blade spin

Looks like most phantom models use the counter rotating rotor pair and not a tail rotor for stabilization, as mentioned one uses trim adjustments to balance relative rotor speeds to stabilize the orientation, have a close look at the linkages connected to the rotor mounts.
