RE: OMG!Just bought a Expresscraft Thunderbolt!
I had problems with mine cutting out when making right hand turns and i'm pretty sure it was a water spray issue. The problem got better when I added weather strip on the carb side but still was soemwhat an issue. I know it wasn;t the engine becasue when I put the same engine in my drag cat I didn't have any problem with cut offs in right or left turns.
