I know this is a very old thread, but I think my question is related to the original theme of the thread to warrant posting it here rather than create a new thread. My question is as follows:
Were there any proposed land based He-115 variants or derivatives which would have had retractable wheel landing gear? Are there any models, blue prints, or what if kit bashes that show this? I haven't been able to find anything to answer my question so far, so I thought I would ask.
