I'm building a micro BAC TSR-2 pusher jet using a radial 1806 and 12a ESC. My battery options are 7.4v 2s 650, or 3s 11.1v 650 and my prop choices are 6x3x2, 5x3x2, 5x4x6, 5x5.3x3, 5x5.5x3 Hulkies. My overall length/fuselage length is just over 17", wing span 8.6", tail plane 6". I'm trying to keep it light as possible. So 2s or 3s and what prop has the best chance of success?
