Big Big problem. First of all, hello from Spain to everyone and nice forum. The problem I have is that it turns on ok but if you take the key off the engine will keep tunning. Even if you press the stop button it will keep running. As you guys will understand this is extremely dangerous, specially if you fall off, the rxp will go running, and unless you are phelps, you won´t catch it...Thanks to everyone that has any idea of what may happen.
