The wheel like thing is your hop up adjustment dial. A hop up places back spin on your BB, if the hop up is set to high the back spin will cause the BB to curve upwards. Adjust the dial until your BB's are flying straight again. That should fix your issue.
I'll leave this thread here as other new users name find it useful later on down the road.
