AIRCRAFT CONVERSION MANUAL
The CORVAIR motor has been used as an experimental aircraft powerplant since 1960. Numerous aviators have logged hundreds 
of hours on them. In 1989, William Wynne began to develop the next generation of CORVAIR powerplants for aircraft use. His goal 
was to develop a safe, powerful, inexpensive engine, and teach as many people as possible how to build their own engine. This 
Manual is the summary of 12 years of William's research, development and flight testing of CORVAIR engines converted for use 
as experimental aircraft engines. First published in 1996, the Manual has been updated and contains the latest developments 
on his continuing work. The Manual is approximately 60 pages and teaches builders how to convert a 110hp. motor into 
an inexpensive, reliable, efficient aircraft engine. The Manual includes numerous drawings and information on the complete 
installation, including propellers and engine mounts. Thousands of Manuals have been sold and William is available with 
technical help by phone or e-mail. To learn more about his work, see www.flycorvair.com.      C11251     1 lb.
HYBRID STUDS
In his continuing work to simplify and lower the cost of converting the CORVAIR motor to an aircraft powerplant, William Wynne continued to develop numerous 
custom pieces. The premier time-saving development in 1999 was his Hybrid Stud. This stud mates the CORVAIR crankshaft's 11/32-24 thread to the 
William's Prop Hub design. (Drawings of the Hub are contained in the Conversion Manual and finished Hubs are available directly from William.) These studs, 
the result of months of development, save the builder hours of machine and press-work time. The Hybrid Studs have been flight proven hundreds of hours in 
William's plane. They are sold in sets of six, complete with instructions.  C11252    1 lb.   
William Wynne AIRCRAFT GASKET SET has everything he suggests for rebuilding a Corvair engine for aircraft use. 
              (must order head gaskets separately if needed – see page 7)  C120WW        2 lbs.
Set of BALANCED RODS (suggested by William Wynne) – includes core value   C9203WW      12 lbs.

AII of the engines we build in our FlyCorvair.com hangar use Corvair parts from Clark's Corvair Parts®. Engine builders who want the same reliable performance can 
utilize the same parts and their core motor to build their own engine. We’ve organized the parts into three specific groups to follow our Conversion Manual and Videotape 
series. For the contents and exact grouping, check out www.FlyCorvair.com.  
All the parts specific to the aircraft conversion are available at www.FlyCorvair.com/products.html. 
Clarks, 
I am grateful for your eorts to work with us on this. I have spent many years ight testing this information and parts.  
My eorts to bring the CORVAIR to mainstream acceptance in the experimental marketplace would be much more dicult 
without the quality operation you and your sta run.
Thanks, 
William
