Thanks Gary for the info. I've got a copy of a tune up guide for Saitos that I got off the web and was going to follow that to set it up but since the tach didn't seem to be working right I just gave up untill I got some new batteries. I can't hear the engine change well enough so I rely on the tach to set the top end.

As far as the investigation of the 737 crash, since I work for Boeing I have seen quite a few videos on crash investigations and it's quite extensive and takes a long time. Yes, they probably know what happened based on how it all went down but have to check every thing to make sure that everything that caused it is addressed. They will probably have an AOG team go down there and rebuild the plane there get after the investigation and get it flying again...........
