Sealing an ASW 28 canopy

Might it also be possible to include a check-valve sort of flap that would
allow exhaust but would prevent dirt from the tailwheel from entering the
tail boom?

I have given it some thought.
Installing a brush wiper at the front and rear to clean the rolling face.
of the wheel. Also a smaller wheel would allow a secondary fender.
The original wheel is about ~7". A 6" wheel would be large enough.
That would allow room for some sort of baffle.

Udo,

Interesting, I'll have a look at my ASH26E.

There appears to be plenty of exit area in the tail of my ASH 26 E
through the rudder horn fairings and openings in tail bulkheads. I
suspect restrictions, if any, are due to the engine box, or even just
stuffing the baggage compartment full with a down jacket, as I do.

Even so, my 26 has too much ventilation flow, so I've blocked off the
left side duct in the nose. I've heard of at least one pilot of an ASW
27 that made the nose intake hole smaller to achieve the same thing. My
guess is Udo's problem is specific to his glider, and not ASW 24 and
later models in general.

Craig Shaber had an exit (reverse NACA duct) installed in his ASH 26 on
the right side of the fuselage near the wheel doors, but I don't recall
if he thought it improved anything. Other pilots have done this to
various gliders, rather than trying to get the air all the way to the tail.

I would agree -- when I had a '24, I thought the ventilation was very good.

why not ask AS sending an email?

Wasn't air able to exit through the rudder horn and cable openings?

It appears the opening is plugged by excess assembly epoxy.
