Is that something one can order or is it some sort of home-brew balsa ply ?
I think I may turn my MA3 I ordered into a Colossus instead with an additional tube and wood fins for strength.

A company called Mach-1 used to make balsa ply. It was available from them and also thru BMS.
It's long OOP, but I still have a some left from a purchase I made years ago.
I also roll my own. I use two outer layers of 1/32" balsa over an inner layer of 1/16". I glue it with yellow glue, then clamp it for a couple days between two very carefully eyeballed (for planarity) pieces of birch. Some aluminum foil makes a good release layer to keep from glueing your balsa to your birch  (which is not quite as bad as glueing your hand to your special purpose  )
