RE: diffrent names?
I believe 'bulkhead' is the simplest of terms... May be for laymen terms you could use: "part of the chassis where lots of major parts are stuck to"... I don't know... That's all I came up with...
But front damper case? I've never in my 5 years of RC heard that before... Today, August 3, 2007 @ 3:54AM, is the first time I've ever even heard the term 'front damper case'.
