Maya Animation Problem

Hi,
I am having some problems with animation in Maya.
I made a model in Maya and Animate it using rigs for animation, Animation is working well in Maya I Export it as FBX
But when i import it in unity, The mesh gets disturbed its sizes of different planes get bigger.
If i check "No Animation " in import setting of model, then model imports ok and it is better shown in unity but no
animation at all.

I am using
Maya 2011
FBX file export Formate
Unity 1.6 Pro

Suggestions Will be appriciated

@qumarzaman - I dont think that U1.6 supports the FBX format in Maya 2k11 - I am almost sure it does not…

Thanks, sboyette for replying But I tried it also
I imported the Animations from different tutorial examples of iphone ( ie, penelop, tut1, etc.) in Maya 2010 exported it as FBX and imported it in unity

also but it didn’t also solved my problem.

same problem occurred with Maya 2010

please assist me in this problem

Get rid of your cameras in maya . Export your file without the Maya Cameras in the Scene ,see if this helps . When I exported from Carrara 8 I had the same problem because of the Scene Cameras.
