Thanks for the input Graham. Does anyone have information on the highest
usual exhaust temperature on the 912.
There are of course stainless steels and other alloys that are resistant to
higher temperatures but they are not always available in the welded pipe needed
for these types of systems and also much more expensive.
If anyone is thinking of buying an exhaust other that the Europa standard system
I would suggest that they wait a little while as Heggemann has suggested that
they could make a system equally as quiet but about 3 Kg lighter (this
alleviates part of the manifold problem).
It is also good to note that they have a Dynometer in house which helps with the
design criteria and reduction of back pressure in the system.
I must say that after 20 hours flying now, with the exception of the
start/landing difficulties the aircraft is a delight to fly and meets or exceeds
all of the specs promised by Europa.
regard to you all
