I am aware of search. I work 12 hour days and don't have the option to spend hours a day searching old posts.
...heh...well, most of us work, too...if you are serious about this hobby, you'll be spending a LOT of your spare time with it; some of that time, doing the research - that's what those of us who have been in the hobby the longest have done...as you must know, there's a great influx of people interested in the hobby now, thanks to Reality TV...it's unrealistic to expect that those who have spent a long time in the hobby have the time or inclination to answer questions previously answered - some many times..."T-53", for instance...if you search that term, you should learn all you need to know from previous posts...
...Bob's right: use the search tool first; post when you have a question that hasn't been previously answered...the 'experts' will respond more readily if they see you've taken the time to do your homework...
