tink, as far as the Cap or Edge goes, I've built and flown the Cap and it's a nice flyer. I've also done the Sukhoi, the Turbo Raven, the Extra, am building the Edge and the Giles and have a Velox on the way to be a foamy little brother for my Aerotech 50cc Velox. All the designs fly about the same except the ones that don't have the ailerons extending all the way to the fuselage. The aileron authority is not as crisp in high alpha flight. BTW, if you're looking for hinges try Klett Plastics in Fort Worth. They have a small hinge point that is perfect for these fomies. I'll edit in a link to a build thread I did on the Cap showing a picture of the hinges on this post.[link=http://www.rcuniverse.com/forum/m_2161373/anchors_2161373/mpage_1/key_foamy%252Ccap%252Cbuild%252Cthread/anchor/tm.htm#2161373] Here[/link] it is.
