I got one of these for Christmas last year and finally used it - for my SM Goshawk to run the tip wing tip light cables and servo lead in the wing. The camera with the little hook was great. I also could see the glue joint and the balsa blocks, most looked ok. Mine came with a wireless screen attachment, that was good , I could leave the screen in one place and work with the other. Anyway, I agree, it is a great tool, I bet I will use it more often now.
