RE: Air Hogs Aero Ace!
yes, it's a defender motor. tought it wasn't a n20 that i had. where do you get them, the n20?
i also tought that the airfoil was a bit to fat. i'll keep the flat botom design but with less thickness.
a big thanks also for the wiki link, didn't saw that page yet. i tooked the airfoil from an old timer model (in fact the first flat bottm i have found....) traced directly from the pc screen!!!
