ROTAX, a name that is synonymous with light aircraft, LSA aircraft and
even military drones and in a co-operation with Pipistrel today marks a
very important milestone in the history for ROTAX with the release of the
new fuel injected 912 IS aircraft engine.

This new engine the ROTAX 912 IS produces 100 hp from what is basically the
same engine core as the 912 ULS with the exception that the carburettors
are gone, now replaced with modern fuel injection. This relieves the engine
from carburettor imbalance and provides perfect start-up/shutdown and idle
just like a modern car. The choke has gone and the engine responsiveness
has been increased substantially along with an approximate 10% reduction in
fuel consumption at normal cruising speeds.****

As the world's leading supplier of aircraft engines for Ultralight and LSA
aircraft, ROTAX aircraft engines have truly revolutionized the aircraft
industry. The popularity of these engines continues to soar higher and
higher, from the original two-stroke engines through to the modern four
stroke engines ROTAX produce an engine for just about every aviation
application and many hundreds of non-aviation applications.

The 4-stroke 4-cylinder boxer engines we are now familiar with and known as
the ROTAX 912 series started development in 1984 having advanced technology
and superior weight/performance ratio and have propelled experimental,
Ultralight, LSA aircraft and motorgliders for many years gaining themselves
an enviable reputation for reliability, low noise, fuel efficiency and most
important actually reaching the TBO times. ROTAX aircraft engines are
available in two configurations including fully certified engines as well
as noncertified engines; both are very similar and enjoy a fantastic
reputation.

Today is a significant milestone for both Pipistrel and ROTAX with the
release of the 912 IS engine, ROTAX have chosen Pipistrel as the 912 IS
release customer and the engine has been fitted and tested on the
award-winning Pipistrel Virus SW aircraft. Those that have flown the
aircraft report increased smoothness, faster throttle response, lower idle
and most importantly for the environment less fuel consumption for this
exciting new engine.****
