The World's Smallest Co-axial Helicopter

it's not quite like the mini-helicopters i've seen before, but that's ok - those other helicopters couldn't lift people...



also, those other mini-helicopters probably didn't cost $30,000 for the kit to build them...

here's a question though, didn't they have one of these on the flintstones? i seem to remember they did...
