Veteran aircraft designer Chris
Heintz introduced his newest light aircraft design, the ZODIAC CH
640, at the EAA Sun'n Fun fly-in in Lakeland, Florida (April 2001).
The new design is a four-place, low-wing, all-metal kit aircraft
The CH 640 is a conventional four-seater,
with a 2 + 2 seating configuration. The prototype aircraft is
powered by a 180-hp Lycoming O-360 engine. The design features a
fixed tricycle landing gear, large dual gull-wing doors, a wing span
of 31.5 feet and an overall length of 23 feet.
Heintz developed the new design in
response to demand from kit aircraft builders for an affordable and
simple four-seater. While there are literally hundreds of two-seat
kit aircraft designs available for construction, there are few
modern four-seat designs on the market: The available designs are
either complex high-performance planes (such a the Lancair IV) or
"utility" designs such as Murphy's Super Rebel and Heintz' own STOL
CH 801. The new ZODIAC CH 640 is designed to bridge the gap between
these utility designs and the fast and expensive composite designs -
to make it a practical and useful aircraft for the "average"
pilot/builder. The CH 640 has a useful load of 1,000 lbs., making it
a "true" four-seater.
