I bought them here at the LHS, which happens to be owned by the Dutch F3A champion, so he has a good stack of materials! It is a carbon gear locally made for a model he designed (it is the same I showed a few pages earlier). They cost 14,95€ a piece.

I am sure they can mail a set, but I assume you can find them cheaper at your side of the ocean.

CG with the old setup was very good, it almost tracked level when rolling inverted (needs just a hint of down elevator). I will let you know how she handles with the new (and lighter) gear.
