Hi Guys.
Thanks for the feedback. It seems it was one of the lower hose connections. I made
the jubilee clips really tight and it seems to have stopped. And Ivor, next
time I drain the system I will change the clips for the Rotax type spring clips
but whilst it is dry, I don't want to disturb it again now.
Richard.

Hi Richard,
It has been my experience that worm drive clips will ultimately leak due to
the thermal expansion & contraction from summer to winter. I ended up using
the spring clips similar to what Rotax use for the coolant hoses on the top
of the engine.
Cheers, Paul

Hi,
Ditto, we had leakeage for years with the worm drive clamps. As the
inner metal fitting heats first (and expands) it crushes the hose
against the clamp, which does not heat as quickly. As it cools, the
crushed hose now has space for coolant to leak from. Later on, you
notice the loose clamp and tighten it a little. The next time you run
the engine, the process repeats itself. We finally switched to spring
clamps and have not had the problem since.

Terry=0AI think what happens is that the hose softens with heat then is com
pressed by the clip when it-takes-a permanent set, which lessens the cl
amping pressure. This-happens-repeatedly so we end up with-=0Aloose c
lips.=0AThe-spring-clips take up the slack as the hose softens and spre
ads so tension is retained.-=0AThere is also more even clamping so that l

Hi All,
Re. Europa RC models. The company was Experimental Aircraft Models, which I
sold to KMP in Canada about 7 years ago. He continued the model line for a
few years and then focused on his larger warbird models.
Gerry, it's great to hear that you still have one of the models, I have two
in my basement in Detroit also in that condition. I, however, am now on a
project in the LA area and so have left my Europa (A198) still project, back
home in Detroit after taking it with me to England.
I don't expect to be back in Detroit for a few months, but if anyone has an
interest in one of them, feel free to let me know.
Still building and lurking after all these years,
Cleve Lee
A198, Was a Jabiru, sold off to 'dumb down' the plane to Light Sport after
some surgery.. Working on electrics and replacement engine decision.
