Here is a nice cast pulley I saw at the Rotorway booth at S&F.

Actually Paul, I doubt you saw this at a Rotorway booth, that looks like a
Pro-Drive aftermarket cog belt system for the Rotorway, very factory
unauthorized, but a more elegant, efficient and low maintainence system than
the leaky oil bath chain drive that the factory puts out.

Rotorway seems on the verge of being overrun by the aftermarket companies.
They just sold their 600 Exec 162, BTW.

Between the aftermarket belt drive, aftermarket tailrotors, and Turbine
conversion kits, some think that soon half the factory ships will be sold
without an engine.

Still needs a proper firewall IMHO.

When I build mine it will have a real firewall, and rollover protection for
the occupants.

I agree with Hans.  I looked at the rotoway booth, and asked lots of questions,
mainly about the rotor blade construction.
They are still sheet aluminum folded over a spar.
No one there could answer my questions, and haven't forwarded the info as they
offered.
That pulley has to be a Pro-Drive.

OK I was wrong. It was not the Rotorway booth. I was misled. 
Thanks for correcting me.
