Hi Bo,
Yes,the sticky fingers! The
Aeroskin was not a bad idea but badly executed in the plastics department. The first pre-WWI sets of early flying machines were
much better. The mouldings were quite fine for the time but they missed a trick by moulding them all in black rather than wood brown.

Buff coloured tissue would have been even better. I still have these models and they hold up quite well even today.
Cheers,
Ray R.
