Yeah, when you say 230mm tc class, that is much different than 1/8 nitro cars. The TC 235mm class (that's the actual size) is dying but not dead. Sometimes the races mix the bigger bock 200mm cars with standard 235mm to make the class bigger, but most of the best drivers don't compete. The reason is the lack of support in the industry and at such big events, the best drivers have responsibilities in 200mm TC and 1/8 scale, so adding a third class is low on the priority list.
