Hi Yunga,
There are several things that can lead to uncontrolled spins with these.
Inspect the tail rotor for any hair or fabric fibers wrapped around the shaft. Anything that impedes the normal rotation will make the heli spin. Even spider webs will cause problems.
Also inspect for cracked blades on the tail. The slightest crack will let the blade bend when it is spinning full speed, and this will change the amount of air the rotor pushes.
there are trims on the transmitter to adjust the centering. Ir it always spins one way, try moving the trim the other way.
Our club purchased many of these helis. 30 or so. When they work, they are a blase. Unfortunately, we had a 50% failure rate. Fully half of the helis would spin out of control right out of the box.
If you are bit by the helicopter bug, consider spending more for a quality model. the Eflight Blade CX2 is a good performer and flyable indoors.
Good luck!
