I just joined the list and have not seen any posts. I have a question or two about airfoils.
I know there is a new critical airfoil for the kr but I was wondering how well it works and if it is so critical that a hacker or a new to fiberglass guy like myself could hope to build it and it still perform? The other question is i know the bonanza, malibu, rv-3,4,6,7,8, venture egg and many other fast planes use similar airfoils: (form http://www.aae.uiuc.edu/m-selig/ads/aircraft.html) NACA 23016.5 Bonanza NACA 23015 Malibu NACA 23013.5 RV NACA 23017 Questair Venture NACA 23014 Cessna 550 Citation Bravo Are these planes fast due to the aifoils or the HUGE engine pulling them? NACA 23013.5 as in the RV or maybe 23013 root and 23014 tip (or maybe i have it backwards) would this be a good choice ? Has anyone tried the rv8(NACA 23013.5) airfoil on the kr with a vw engine? I was putting together my plans to build a kr1 (modified of course) making it a bit longer and different airfoil and wing taper from the fuselage. Please tell me if you know which wing would be the best and fastest. I don't mind a higher stall speed or the longer take-off landing as it will mostly be operated form improved surface longer runways. thanks jerry
