Same thing happened somewhere in Arizona I believe when a RC plae struck the man who was flying it right in the chest!....I know it happened some time ago just cant remember how long ago....
RC Vehicles are dangerous....when I first got into RC car racing I was turn marshalling on the track and suffered a broken foot when I got nailed by a car.....the thing actual hit me full force(knocked me off balance and I fell)...that was a few yrs ago.
We have had various accidents over the years at our club races....and heard of really wild ones from other clubs.....Such as an 1/8th scale buggy hitting a jump and going off track and through a jeeps front window! Saw a picture of that on the RCCA boards last year!
