Welcome to the first edition of Good Idea/Bad Idea! (shamelessly stolen from Animaniacs) If you guys see any kludges that can be done better or worse, submit them for comparison!
"Some say rust and electronics don't go together. Some say you must properly ground old electronics. I say that having a ungrounded, old, rusty 1300 RPM propeller near my head is better than being hot!"
Better you than me, buddy!
