Designed For Extra 300/330 Applications
Hartzell Propeller has developed an advanced structural
composite propeller for aerobatic aircraft using its proprietary
ASC-II technology. The new Claw 2.0 propeller has recently
achieved FAA type certification, meeting all of the propeller
certification requirements. The original 'Claw' and the new
Claw 2.0 are the only certified advanced composite propellers
available for aerobatic use. The propeller has not yet been STC'd
on the aircraft; however Hartzell is making the Claw 2.0 propeller
available now for Extra 300/330 series aircraft flying in the
Experimental category.
Former US Unlimited Aerobatic Champion Michael Goulian used an
experimental development version of this propeller on his Extra
330SC during the 2009 airshow campaign, for which he was recognized
with EAA's Bill Barber Award for Airshow Showmanship. He was
so pleased with the new propeller's performance that he will
continue using it during the 2010 air show season.
He said, "I couldn't be happier with my new Hartzell ASC-II Claw
2.0 prop. It has displayed all the characteristics that made
the original Hartzell 'Claw' a market leader, but from a
performance standpoint, it has more pulling power at the low
end. It also has a more modern look. It is a natural and
worthy stablemate to the 'Claw'."
"As someone who makes a living flying a high performance
aircraft, I need my prop to be safe and reliable 100% of the
time. Hartzell was always my choice, and with this new prop
they haven't let me down."
This latest model from Hartzell comprises a unique lamination of
carbon fiber and Kevlar, with an electroformed nickel leading edge
erosion shield. The composite structure is co-molded on an
integral stainless steel shank that accommodates bolt-on
counterweights needed for aerobatics.
The advantage of installing a certified propeller on
"Experimental" and homebuilt aircraft is that it has been
rigorously tested according to FAA standards, and users can be sure
the propeller will withstand all flying conditions. The Claw
2.0 has passed all required certification tests including bird
strike, lightning strike and fatigue strength. It has also
passed a vibration stress test over the entire aerobatic envelope
on Goulian's Extra 330SC.

Mike Disbrow, Hartzell's senior VP
marketing and customer services, said, "The new ASC-II Claw 2.0
prop is the perfect addition for "experimental" pilots who like to
push the limits of their aircraft's capabilities safely.
Michael Goulian has shown that this prop can perform under even the
most extreme."
Hartzell's kit for the Extra 300/330s includes the 3-blade
propeller and a carbon composite spinner at a special introductory
price of $21,900, with a three-year/1,000-hour warranty and
6-year/1,000-hour TBO.
