How not to build a Ultralight rotorblade

haaaa ... good one ..... both frightens me and makes me laugh

He should get an award for the highest inertia blades ever built.

I am comforted by the fact they will never fly.
 
Skyguynca .... thanks man ... this is great entertainment for a cold winter evening.

To build the tail rotor all you need is an angle grinder gearbox ... do some welding on the bearings to "heat treat them"

 
weird... I've never seen a symmetrical airfoil mirrored in a way that the leading and trailing edges were the same. Must be aerobatic.
The identical shape of the leading edge and trailing edge is so that reverse airflow on the retreating blade can provide lift.
He should patent his solution for retreating blade stall.
And just think ... all it took was some mild steel and a few rivets.
 
His name is Joseph Bensen, a distant relation perhaps ?
 
"90% of the most advanced helicopters in the world today have autorotation" (!)
 
I find these videos are great entertainment .... I also consider he is just "pretending" to build an actual helicopter... trying to get millions of Youtube hits or something.

The guy is no dummy .. has a couple of higher end cars in his driveway ... I think he is pranking us.

Bottom line ... I confess to enjoying it all . Cant wait for the next episode .
 
Now, now... these blades will fly equally well turning in either direction. Brilliant. Stop 'em in flight, shift her into reverse and wind them them up in the other direction for an easy way to fly backwards.
Didn't think of that. I thought it was for going back down. Huh.
