When I get my Magnum back, thats if they replace it, I'm gonna give it another chance. I really dont know what made it burn up but I believe it has something to do with the this magnum using a wand under high torque conditions. I had started up all my planes, including a couple with OS160's and it always worked fine. There are some other guys using it at the field with airplanes only, and they have had no problems. When I get it back, I may just make it an airplane starter, and keep the Kevan reserved for my Freya. Daz...
