Hello all,

We have just ordered a spin ballast kit (Tn 4a) for our ASK 21 from
Schleicher. Can anyone relate their installation experience before we,
pardon the pun, auger in? Specifically about the drilling the 12mm hole and
the fiberglass cloth lamination. For those curious, I shall convey back our
own dealing once the exercise complete.

Cheers
