Mike,
I am deleting old emails.
I came across this one of yours.
Re rain ingress - you are an inventive sort of person -do you have any
suggestions?
I note you did not suggest anything at the time.
Is it a problem, other than if the glider is tied down outside?
Have you further considered the matter? If so what did you conclude?
Has anybody else given the matter any thought?
Gary

Subject: Re: [Aus-soaring] Air vent
When we were discussing the DG Mandl extractor air vent some time
ago I think I mentioned that the best location would be on top of
the fuselage in the low pressure area.
It seems either somebody saw that or had the same idea. Blending the
vent tangentially to the rear was always a good idea and is commonly
used in engine cooling. Nice touch to add the louvre. This looks far
better than the relatively crude DG vent. Might want to organise
something so rain doesn't get in though.
