Hey Guys,
I have a Great Planes Ultimate with a MT-57. I was flying the other day and the spark plug blew out of the jug and stripped all the threads out. Has anyone else had this problem before. This motor has less than three gallons of fuel through it. I have a reasonable quote to fix it but I would have never thought this would happen. I was able to dead stick land it with no problems.
Going to tear her down next week and get it fixed.
