The 36" mambo had a fuselage built like a sherman tank and would lend itself to much lightening. It contained a lot of block balsa. the slab sides could use some lightening holes with no ill effect.
I am totally unaware of it's flight charateristics but I have seen them fly on rudder only and do some pretty good stunts. It's all in the thumbs.
