Spitfire MKII Nitro with New Muffler

Brought my big bird out today to check the new sound of new T Muffler on JBA 91AR engine and also to Enjoy flying it. It was again sitting for a while at home. Flight was beautiful as always, Engine performed and sounded much better with New muffler. Just the landing was ruined by a careless man on bicycle. I wish we had a proper club, with proper runway and people control :(
