I am getting ready for my winter project and I had a question. I hope to build a Balsa USA Eindecker .90 size. What engine have most put on it. I know it calls for 40-60 2 stroke or 60-90 4 stroke.
It will sound better with a four stroke, most vintage aircraft sound great with a four stroke in general but a little over sized and propped large they really take on a new character compared to a screaming 2 stroke. I'd use at least the 91 FS if not larger engine and as another poster mentioned use a larger prop with low pitch.
For a two stroke I'd use the 60 and build a custom muffler for it or it will sound terrible.
