This one is a Simon MP-40. It has an air cooled Duetz 2 cylinder. Basic switches solenoids, etc. No circuit boards.
It needs a battery, and only operates from the ground controls. Again, hoping for simple electrical/switch issues to repair. The drive seems weak, but I'll look into that later.
I hate heights, and weigh 350 pounds, so ladders are not my friends. I'm hoping this will help with the teardown and repairs on the house on my new property, plus tree work.
