That is a picture linked from another thread in RCU in the crash forum. It is an old picture that has been there a couple yrs.

There is a link to the thread in one of the earlier posts

I had an accident like that twice. One in the 60's just like in the second picture and then again last summer. My fingers are all heeled on the surface but the nerve damage and arthritis will bother me for years.

I started a Saito 56 and it was at low idle. I drug my fingers that I has holding the plane down with through the prop. They didn't stop the engine. It cut 1/8" off my right middle finger and broke my ring finger behind the nail and it looked like it was cut off and hanging by the skin at first.

People should be aware how dangerous even a small engine can be. The original poster in that thread link cut the back of his left hand with a small electric model. He had tendon problems that resulted in the need for a second operation on his hand.
