I recently bought a Swift mini helicopter model #6020-1. Its a great helicopter ,but I was flying it yesterday and it lost its signal and fell too the floor(stupid infrared)I put new batteries in the remote and started too fly it again but it sounded funny.I looked at it more closely and noticed that the whole roter shaft was loose,so I took the whole heli apart and found out that the gear assembly had moved down the shaft.I then moved it back up and put back together.Now when I fly it , instead of hovering in one spot it starts to rotate in about a foot wide clockwise radius.Trimming doesnt help.Anybody have any ideas ,Ilove this little heli. I would hate to buy another one if this is simple fix.
