RE: Gap Seals

[Tony S. Krzyzewski <tonyk@kaon.co.nz>]

On ZK-UBD we have a door stop foam seal with a fuzzy cloth upper surface
inside the flap closeout to close off the flap gap in flight and then
mylar glider seals on all of the other surfaces. The mylar seals are
available from most gliding supply shops such as RD Aviation in the UK. 

You also need to pay particular care with the seal at the wing root. Kim
Prout pointed me in the direction of a flexible door sealer to fit
inside of the flange.
