Actually those were mainly injuries from plank propellers. Foto of Roman Pirozek head after accident is much worse. I will not provide link because I respect victim of accident and his family.

If newbie asks me to help him start with 700-800 I would show him this photo first as a warning for sure but I would also help such person to setup the heli, verify his skils on the sym, find appropriate empty field for maiden and first flights.

After three lethal accidents in 2013 I have started to fly more carefull. I include death of 18 months old girl in Asia and accident in Switzerland.

Statistically we are safer at the field than on road while driving to get to the field.

 

APC plastic props are the worst offenders by far.

They are so sharp and even the slightest nick from one leads to stitches.

There are far more injuries from planks than helis probably because helis scare most people with they're big shiny spinny things on top
