I disagree with the statement regarding maintenance.
A fibreglass ship will always cost less to maintain
than a fabric over metal ship.

I don’t believe a K13 is move forgiving than a Twin
Astir or K21 for training purposes. And, in the unlikely
event of an accident I would rather be in a glass ship.

Isn't it rather difficult to get a K21 to spin? So it must be next to
impossible to do spin training in the glass job?
