test flew yesterday on the commons - flew excellently in some wind - excellent excellent looping with no rolling off or tip stalling. roll rate and inverted is fine too. will be fine for indoor and real fun for backyard for more urban flying. dollarama foam - stripped rear portion and elevons, but mylar plus paper on the front portion. stiff and strong, but coulda been lighter with mylar only. symmetrical KFm-4 airfoil. tapered wing keeps thickness along span (bigger % thickness at tip) so helps prevent tip stalls i think. another cheap and easy build.
33" span, 4.7 oz all in
6x3 prop, 10g motor, 350mah batt, 6a esc, 3.7g servos
