I forgot to add: Most Clubs I know don't use the tail ballast to
demonstrate spins to students anyway, but to do primary aerobatic training.

One of the wonderful things of the ASK 21 is its versability: Docile
primary trainer, capable aerobatic trainer, certified for cloud flying.
One size fits all.
