Depends on what you mean by letting go? Is is a gear problem or something else. You can always send it in for a quote. It will probably cost $15 to $20 to fix it plus parts, but I am guessing at that. I think there is a $15 min. Otherwise, if you can get one cheap enough, order a new one. I generally just replace servos any more unless they are the expensive ones I paid over $100 for.
