With the recommended motors both being Estes BP 29mm for the GG my guess for that one at least is balsa. The projected altitude in the catalog is 880 feet - adding the weight of plywood plus the 3.4” stretch of the body tube I don’t see how an Estes F15 would ever hit that. Even with balsa that altitude doesn’t seem likely, at least anywhere other than maybe from a launch site already a mile above MSL!
