I am aware of at least one non-SciOly indoor glider design that uses a carbon fiber fuselage and tail boom. There are several drawbacks to this design option. 1) cost; 2) requires different adhesive for proper bonding; 3) potentially uncomfortable carbon fiber splinters; and 4) awkward joining of flat wing and stab surfaces to a round carbon fiber fuselage and a round carbon fiber tail boom, respectively.
On the good side, a carbon fiber fuselage and tail boom arrangement would be very light, rigid and strong if the proper diameter(s) were selected. Variations in humidity would be less likely to change trim if the glider has a carbon fiber tail boom. While breakage of a carbon fiber fuselage and tail boom as a result of a crash would be unlikely, there would still remain a significant possibility of fracturing of the wings and/or the wing/fuselage/pylon joints as a result of a crash.
On balance, partly due to the small scale of the 2014 elastic launched glider, and the 3.0 gram minimum weight, probably a lot of time and trouble would be saved by simply using a tapered stick of harder balsa, e.g. 8-10 pound density, for the fuselage and tail boom.
