As of today, Americans still only account for 3/131 entries. I wish I were one of them. Good luck to Dylan, Zach and Brad.
Concerning the decision to put the kibosh on efficient solid wings: I'm pretty sure it was made in the interest of keeping the class members happy for the near term (and, yes, because we are a class with a "una-rig" to use an old term) but that a collateral effect was to move the moth off the bleeding edge of development.
I'm looking forward to reading about the championships, now only 2 weeks off.
