Well THERE'S your problem. It's making a horrific sound. Some kind of terrifying rhythmic noise is emanating from your motor. I thought it was going to explode in an enormous fireball. Good thing with your quick thinking and lightning reflexes you were able to bring it to the ground in an emergency landing before that happened! Di you get any noise complaints from the neighbors? I wouldn't be surprised if the police showed up. Or representatives from the local church... That's a devil sound.
