2 minutes into the test flight of my new Razzle, the right stab and elevator blew off it. Luckily I got the plane down relatively in one piece. Once down the ooh-arr squad noticed that the left stab was cracked as well. Anyone else with similar problems?

Engine: OS .61 FSR
Prop: Bolly 13.5 by 6.
PS The plane was flying straight and level at less than half throttle.
