I have a mcx and love it, i was doing some research on the cx2/3 and found this video<a href="http://www.youtube.com/watch?v=nGUTAwItRAM">http://www.youtube.com/watch?v=nGUTAwItRAM
a</a>nd I realized my mcx was performing the same "toilet bowl effect" as seen at the begining of the video. And even with fully chargerd, brand new e-flite batteries, it doesn't want to stay elevated when it hovers. So would it need a new upper rotor head when it starts acting like this, like the cx3?

EDIT: I also forgot to mention it wobbles lately while doing pirroettes.<br type="_moz" />
