I see that you have recommended a Metal Gear Servo with the S3102. I'm uncertain what the ''weak link'' is in a servo that is subject to cyclic shock, as I suspect would be the case with a nose wheel. But I think that the simplest/cheapest/lightest way to mitigate a failure would be to use a Metal Gear Servo. I think I'll get one.
I wasn't thinking about the metal gears when I looked-up the servo. I was thinking about price. You don't need a top-end, high-powered servo for the old-style Pattern models. Just a midrange servo (both midrange in power and price).
