This discussion has been interesting but I believe the original question was concerning spars for indoor models and I would guess that it was aimed at F1D construction in particular. So here's my take on the use of carbon laminates (and some of you may prove this incorrect):
LPP, OPP, F1M - carbon tubes, rods or balsa/carbon laminates are all good and logical choices.
F1D, HLS, F1R - anything that has epoxy in it is too heavy. Carbon thread or boron applied with acetate glue to balsa is about as heavy as these classes can stand.
