Hello all-
What do you use for your very large diameter airframes? I am working up a project with a 24-25" diameter and am looking for options to keep it as light as possible.
The two options I have seem used are either fiberglassed sonotube (fairly inexpensive but heavy) or composite bulkheads and stringers with foam inserts (fairly light, but expensive).
Does anyone have another option?
