Kinetic Research Cuyuna to 2si from
the past to the future! |
One of the original engines used in the ultralight industry during
its hay days was the Cayuna. It was first used on a plane called the "dactyl" by
a man called Jack McCornack.
If you subscribe to Ultralight Flying Magazine you have probably followed Jack's
adventures over the past two decades. For those that haven't had the privilege, Jack was the first person - at least that I am aware of to cross the U.S. in
an ultralight - that being a "dactyl" powered by a single cylinder direct drive
Sachs engine back in 1979!
Jack also was one the first to introduce the "Cayuna" engine into the sport. The
engine became very widely used in the early 80's and was redesigned and produced under the
brand name UL202.
"Cayuna" then merged with "AMW" another engine manufacturer to form
2si - 2 Stroke International. Now 2 si has turned the marketing of the 2si engines
back over to Kinetic Research.
Kinetic now offers the full line of 2si engines to the ultralight community. This includes
the "son of Cayuna" - the 460 F 35. This 35 hp engine is very light coming in at
around 70 lbs complete. This has helped several ultralight manufacturers produce
ultralights that meet part 103 in the U.S. - like the Kitfox lite and the Aerolite 103.
The next engine Jack offers is the 460 L46 which is liquid cooled, and comes with a gear
drive rather than the belt drive used in the 460F. It puts out 46 hp with dual cdi
ignition.
For those needing more power Jack offers a 3 cylinder - 70 hp version, in 699 cc.
This engine is offered with two different electric starters one that mounts on the side of
the engine and one that mounts on the front. This way it can be better fitted to aircraft
where length is a problem. The company has a very simple warranty - one year parts and
labor from date of shipment. With engine TBO recommended at 500 hours and crankshaft
replacement at 1,000. For more information contact:
