Just read a post about a power switch and it reminded me of this story. My brother had a Ugly Stick .40 size, back when you could buy the kit quite a few years ago. He was flying and the muffler broke. After that happened he couldn't get it to idle right so for some reason that escapes me now we decided to hand launch it. I picked it up and gave it the heave ho. It flew about 50 feet and augered in! I had turned the power switch off somewhere between picking it up and throwing it! Something to think about if you like hand launching is putting that power switch somewhere hard to reach!
