Try the Hobby Lobby Quasar biplane....over 400sq in wing area at 10oz weight. Perfect for your Axi and TP730 pack which is how I fly mine. Its pretty flimsy though and with carbon fiber x-braces in the wings, outside of the cabanes, and tail, its solid and stiff and flys outstanding. Knife edge loops in about 20 feet diameter...a touch of rudder for knife edge, super harriers and rolling harriers and rolling circles on the deck are very comfortable.
