Last year was my first , I built a ctb16 kit , had a ball , I got it bad ,guess I always did. Over the labor day weekend I built another kit ctb16 works fine , my LOR software crashed so once it reloaded here we go. This year almost twice as many led lites, amazing what ya can find at thrift stores . My heart Doc told me not to get on the roof, HMMMMM !!!!. The folks on the forum have been a great help, even on a holiday weekend, Thanks a bunch.
