I’m looking for suggestions on a sheet good to use for cutting aircraft (multirotor) frames. I’d prefer to stay away from metals. Ideally a material around .125" thick and in at least 12x12 sheets. I can get a high-ply hobby plywood, but it’s most common in 6x12 around here and is very expensive for what it is.
Needs to be stiff and durable, not flexible like an ABS or UHMW. Maybe some other sort of polymer I’m not aware of?
