Hector_Slam mapping Hokuyo

Hello I'm trying to create something similar to this http://www.youtube.com/watch?feature=player_embedded&v=F8pdObV_df4, but i'm not able to create constant good maps. I'm using hector slam with the hokuyo URG-04LX and an imu for roll/pitch.(so no odometry) Some (indoor) maps are perfect, but if i try it again the map sometimes drifts and the position in rviz becomes weird.

So my question is: Hector_slam creates its own odometry right? Or do i have to add odometry for proper map results? Or is my laser scanner to weak for hector, so that i need something like hokuyo UTM-30LX?

Thx for your response
