RE: Ziroli Stuka wheel spats mounting question
I suggest that you mount the spats to the landing gear, and not the wing. The LG flexes on landing, sometimes forcing wing mounted spats through the sheeting. Leave 1/4" space between the spat and the wing.
I threw the ABS spat covers away. As you said, they don't fit. They are cosmetic, not intended for mounting the spats.
