I have asked Ripper about enhancements that he added to his F-16 Here . He told me that they came from an issue of Kartonowy Fan. I also know of enhancements for the Halinski P-39 kit that were published in a different issure of Kartonowy Fan. Are there any other kit upgrades or enhancements that have been published in Kartonowy Fan that anybody knows of? I would specifically be interested in more Aircraft enhancements, but if others exist for ships or tanks or what have you, I would enjoy knowing about those also. Thanks for any help that anyone can give me.
