Talking about engine sounds, I was just about fooled on the sound of a Big SuperTiger 3000. I thought it was a normal gas engine sound with CDI ignition. Afer the guy landed his warbird, when asked he told me the engine was running on E85 with a hot "F" style glow plug. I am not trying to convert anyone to do the same...but I may try it. It sounded very good! Capt,n
