Ok, so today out of the blue my helicoptor just started going in small circles. I don't mean the nose was going in circles, i mean the whole thing was. Like It would Drift Forward RIght, Back Right, Back, Back Left, Left, Forward left, forward. I dont know why its doing it but it is making it hard to fly my Blade CX2. The nose stays the same direction, any help?

Sounds like a blade issue. Too tight or something like that. Check them to make sure they are loose enough to find their center when spooled up.

How do I loosen it? Im total noob !!!

You dont, its a CX2 the blades cant be to tight.

tbe, check the stabalizer bar to make sure it's not bent.

You problem is so common that it has an acronym.

TBE for Toilet Bowl Effect.

Usually a bent shaft. Search for TBE and you'll find a lot of stuff.

Its the stablizer bar, thanks~!!!
