Chevy Power Anyone?

Corvette Powered Seabee!
UP-DATE!
Received an
update
from Brian Robinson last week (10-10-2003), it reads:
Hi Steve,
The V-8 continues to outperorm our expectations. To date we have
856 hours on ILM. The total flying time for the 3 V-8 Seabees has passed
the 1000 hour mark! Our actual operating costs are one half of what it
was when we operated the Franklin. The extra comfort and peformance
is a bonus. We just deliverd our first unit for a Murphy Super
Rebel. It is a shorter version of the Seabee unit & will fit a variety of
homebuilts.
Regards,
Brian

CONVERSION FOR SEABEE
Hi. Thanks for you're interest in our Seabee
conversion. The following is our status to date. First flight: 13 July
2000 Total Hours to date: 446 as of 10 Dec , 2001
The conversion has exceeded our expectations
in terms of comfort, performance, reliability and operating costs. At
the 100 hour mark, we removed the reduction unit from the Seabee and
performed a complete tear down and internal inspection. The unit looked
like new
inside and no maintenance was required. We re assembled the unit and
put
it back into service using all original components.
The operating cost reduction was a welcome
surprise. The reduced fuel consumption, & difference in price
between aviation fuel & automotive fuel, has resulted in a direct
operating
cost reduction of over 40% compared to the Franklin. When I compare it
to
a GO-480 powered Seabee, the direct operating cost is cut in half! The
conversion mates the Corvette version of the G.M. LS-1 engine to a cast
aluminium
reduction drive designed specifically for the Seabee. The conversion
has
been successfully flown using both standard Seabee 2 and 3 blade
propellers.
The fuel of choice is premium unleaded automotive fuel. It has
significant
number of flying hours on 100 LL aviation fuel and performs equally
well
(e.g. trips to Oshkosh, Sun-n-fun, Key West, Quebec City, Speculator
and
Otsego). Our Seabee is equipped with automotive style heating and air
conditioning
systems. Both of these systems have been tested during summer and
winter
flying and are welcome additions. We are currently producing conversion
kits
for other Seabees and will have the next three flying by the spring of
2002.
Contact magazine published excellent coverage of the project in issue
59.

The following comparison
chart was based on tests using our converted Seabee (CF-ILM) and a
Seabee
powered by a low time Franklin overhaul (C-FHPH). The flying was done
back
to back on the same day and by the same crew. We have a PowerPoint disc
available which includes pictures of our conversion and the redrive. If
you would
like a copy please provide us with your mailing address. If you have
any
questions that the Contact magazine article or the enclosed information
doesn't address, please feel free to phone me at (705) 374-4347. If I
am
not home, leave a message and phone number.

BILL LAWSON PUTS A FINGER ON
The real problem is that, while you think it would be logical to have
an experimental category for powerplant development etc., there is not
one. We need to send letters to the FAA and especially to our
congressman
urging them to support a new category of Experimental Aircraft aimed at
developing better propulsion systems for existing aircraft. This
category
would allow people to develop and supply engine kits, like you see
available
for experimental airframes like the RV series, for retrofit on
certified
airframes and then licensed under an appropriate experimental category
so
they could be utilized fully like existing experimental class. The
existing
class of Experimental Exhibition only allows you to fly out of one
airport
and for any travel you are required to get permission from the FAA for
every
flight. This does not allow the utility that is available in the
present
class of experimental aircraft where the whole airframe is built by an
individual. Thus for the Robinson chevy engine conversion to be
available in
the US we need to change the rules. Thus write your congressman!
