Hey Thomas,
Yes, I was there. Got 2nd place in the B-final Mod class. I ran my Mini Infero ST for a few qualifyers and then used my RC18B Exotek for the last qualifyer and final (for no reason other than I wanted to try both cars).
The Atomic Carbon held up a treat but we think they are slightly over engineered and Jonathan is looking at making a slightly flatter version (say 3-4mm carbon).
If you are interested in a pair please Jonathan or myself know. We have a few people who have been asking after these now so a production run might be nearing a possibility
