Proven design provides usable horsepower. This means
greater pulling power for effortless, more constant
speed during aerobatic patterns, even with large heavy
models.
Only the finest materials have been selected. The crankcase
is an expensive investment casting rather than die casting
resulting in a much stronger case at the same weight.
A massive hardened steel crankshaft rotates on two ball
bearings of which the front is sealed and equipped with
a re-circulating oiling system to eliminate blow-by
and dirt contamination. The connecting rod is machined
from aluminum bar stock with phosphorous bronze bushings
at both ends. The piston is forged and domed for both
power and crown strength. An O-ring seals the composite
backcover instead of an ordinary paper gasket.
This
engine is known for its contest winning ability. Contest
winning is, of course, an important indicator of engine
performance. Perhaps more important to the day-to-day
sport flyer is long life, dependability, and ready
availability of parts and service. These are assured
with the K.61 because it is produced in the U.S.A. You'll
be proud to have your aircraft powered by the
K.61.
