A man was standing on the scale, sucking in his stomach.
The man's wife sarcastically said, "I don't think that's going to help."
"Sure it does," he said. "How else could I see the numbers?"
The HKS-700E is a 60 hp, horizontally opposed, two
cylinder, four stroke engine. The 700E uses a combination of
high technology and simplicity to achieve the twin goals of high power and reliability. Every major component on the
700E has been designed and tested for light aircraft use.
The 700E engine employs modern
features .such as a multi-valve, oil-cooled head design, nickel ceramic coated
cylinders and dual .electronic ignition. The valve train is operated by a single cam
with cylinder encased .push rods. Valve lash is maintained hydraulically. Torsional
vibration is controlled with .the use of a large diameter flywheel between the crank and the integral
gearbox. A dry.
sump lubrication system is utilized, allowing both tractor and pusher
aircraft installations.
To ensure consistent performance and conformity, each HKS-700E will come
fully .broken-in and dyno tested at the factory for 11/2 hours.
In development for over three .years, HKS has created the engine that OEMs, flight schools and pilots
have been .waiting for.
