I used my Vividia VA-400 rigid borescope last weekend to have a look down inside the cylinders of my Jabiru 3300. The engine has about 360 hrs now, and things look good. I really like being able to see inside at the pistons and back at the valves. Helps give a sense of how they are doing.
I posted a write-up and pictures on my website if you want to see representative pictures for the inspection.
