>>The AS504x airfoil: how does it compare to the RAF-48 airfoil in the real world? From what I understand, its an all around higher performance airfoil, while still maintaining the same sort of flight characteristics as the RAF48. Are there any downsides to this airfoil? <<
Other than the info that I've already posted at http://www.krnet.org/as504x/ , there's no new news. I don't know of anybody else flying the new wing other than Troy and Dean, although there will be several in 2004, Germany's Herbert Fuhle among them. Troy is still quite happy with it, and Dean never had the RAF48 to compare it to on his so he really has no basis for comparison. I personally know of not one single downside to the new airfoil, other than what Dan said, which is that it would be best to take care with surface finish, which most builders pay particular attention to anyway, from what I've seen...
