Is there any legal way to fly an inline twin-engine aircraft with only a single-engine endorsement? For example, if it's an ultralight or amateur built?
I understand Rutan's Defiant was an inline twin that could take off, fly and land with either the front engine, rear engine, or both.
I assume you can do this in a twin inline ultralight as there is no twin engine ultralight endorsement in USA or Canada.
I'm asking about the ultralight or amateur built categories in the USA or Canada, not the US LSA category as I understand they are single engine only.
