AMCL laser scan, TF, Rviz problem

1)I am doing a project on AMCL of a quadcopter and now I am facing a problem where my laser scan couldn't work (running stage simulator,willow-full.world). **Error: I have another question,

2) What should I do in order to localize my robot on rviz with exact map while I am running it on stage simulator? By creating a static tf? How should I do?
