3 or more rotor blades ???

@Zzorse it is currently under wraps. You never know, it might be a 4 seater. -Trenna

You are a nice person. Thanks for the reply.

Fusion Copter is about to learn the hard way that criss-crossed see-saw rotors don’t work. Cracked hubs/blade roots.

Hi Chuck,

Is it predictable where the cracks will begin in the hub/blade root?

Surely Fusion is attaching strain gauges of some type to at least understand the magnitude of the bending loads.

Chuck do you have and would you post a couple of photos of the rotorhead ? I’m impressed, I would like to see what it looks like. I’m not thinking of building one, it’s just something I find very interesting.

The cracks generally start in the attachment region; blade to hub.
Part of the problem results from the stresses being internal to the paired rotors and not producing external vibrations.

there's a picture at the end of the film clip in my post #49

I thought the video ended. Must have been buffering , sorry. Not really, I get to watch it again haha

Ok I watched it all. The rotorhead detail at the end was exactly what I hoped to see. I found it a fascinating piece of machine work. It appeared to work very well. If I may be so bold to ask, why aren’t we seeing more Beaty three blade heads and systems out there ? Your product looks to be light years ahead of present designs. I hope to see you flying it again. I can’t believe something that special is tucked away.
