Not a scratch on the servo? Is that a reliable determining factor for whether a servo is 100% functional? How many people here have servos where the gears stripped, motor failed, ic board failed, wiring failed and the servo from the outside looks perfect? Probably more than 80% to 90% if I had to hazard a guess. Anybody ever strip gears out but the servo looks perfect from the outside just as one example? Of course.

Does anyone here use the aesthetic condition of whether a case is scratched or damaged as the final determining factor of whether a servo might be faulty? I had to point this out because that statement of whether your servos were scratched or not cannot be the determining factor as to their post crash health.
