Don't know much about Kismet but I think Sean has the right idea.  The Epic forums would probably be a better place to ask questions about the Kismet editor though.  Of course you could subclass the Redeemer and modify anything you want from there.  Try using this file:

This is a modified Redeemer with a shorter respawn time and there's no delayed start.
