This doesn't necessarily apply to Lancairs, unless you have a Lycoming IO-360 with an ECI camshaft.
I few months back I posted an email describing a camshaft failure I experienced on takeoff at about 300' AGL. Admit it. Your morbid curiosity has been wanting to know what a broken camshaft looks like. Close up pictures would be great, right? Well here you go. The entry on my camshaft starts at the bottom of page 14.
My engine now has a new Lycoming camshaft.
