Hello Doug,

I have heard similar things about the 2.2 Jabiru. Short prop not efficient,
and also the engine tends to overheat as the 701 is to slow for efficient
cooling. The jabiru-plane that the engine was developed for is a fairly nippy
little thing and moves much faster. Here in Australia a lot of 701 are
buzzing around, but hardly any have the localy produced Jabiru engine in them.
Food for thoughts....

Cheers from Downunder,

Chris from Perth

Yesterday a couple of people who stopped by to look at my progress on
my 701 asked what engine I was planning. When I told them I planned
to use the Jabiru 2200 they said that they had heard that there was a
potential problem using that engine. With the 3300 RPM engine speed,
the Jabiru required a shorter prop than a Rotax. Their argument is
that with a shorter prop the Jabiru would not work as well as a Rotax
(using a longer prop) because less of the prop extends beyond the
cowling. Note: My calculations are with the Rotax running at 5800 RPM
and a 2.43 gear box the prop is only turning 2380.

Has anyone else heard this from a reliable source? Has anyone
experienced any issues with the Jabiru on a 701?
