See my M26A1 build, all the pictures of the camera and mounts are there. Camera is wired into the main battery, it's powered on when you flip the switch and before the motor sounds. Same wiring diagram as posted in my Panzerkampfwagon III build, camera wires attach to main junction block in lower hull, same place the board and fan get their power from.

Question everyone: How often do soldering iron tips last? I have a 30 watt Hobbico, a 30 watt Dremel and once the tips get black they're next to useless. I've been buying replacement tips for the Hobbico but they only seem to last a few hours before turning black and needing replacement. I take a wire brush to them but it doesn't seem to help. What am I doing wrong or is it the equipment?
