I am looking for a new project, and it has to be as a first prefrance from a 5 to a 9 cylinder radial areo engine, 1/4 or 1/3 scale. I know of the state side ageless engines engines but do not like them.
Are there any commercial/published designs out there available from any country to anybodys knowledge?
Very grateful if anyone could let me know or make suggestions.
Thanks.
