Dear Dennis,
our Hungarian Combat team is technically very-very close to Ukrainian team, all the technical resources are common between them, but ours -as they are native Hungarians, and all have double nationality- are competing under Hungarian flag/colors. As I have seen, they use mostly glassfibres, exclusively in epoxy resin. Not for the cheaper price of glass, but not so rigid as the carbon. And the weight does not matter by Combat.
Shall I connect you with them, in a PM?
Are you maintain your eventual Hungarian roots and connections? I am asking after your family name...
Regards: Istvan Travnik (some times TM of Hungarians at a WCh or EChs... )
