The below thread is a discussion on injuries caused by props over in the Crash and Rebuild section. Gives you an idea of the injuries that these plane engines can cause(with some pics) when folks aren't paying attention or doing as their instructor taught them...

Good reminder of the need to be safe! Let that knowledge your instructor shares soak in. Practicing safe handling of your plane will help ensure you and those around you have a positive experience with this hobby.

Also not a bad reminder for experienced folks. Opened my knee up roughly a year back with an OS 46 AX. 12 stitches across the top of my kneecap and a month later I was able to start walking somewhat normally again. The recovery process sucked and was very frustrating. It's a lesson that'll be with me. If posting the above helps one single person remember to safely handle their plane, then I'm happy.
