Hi Tom, I know this thread is an old one but I thought you may still be watching it. I'm about to start a re-covering of a Spacewalker II that I got in a trade. It was covered in monokote and looked awfull. I have decided to cover it in fabric as it should be. I'm wondering if you have any advice on engine instalation. I recently picked up an OS Gemini 160 for the plane, my last part needed, and wanted to know if you had any problems that you ran into.
