Turns out it was just some stripped gears. My servo is the PM 3401 servo chrome and orange. Hoping the stripped servo gears didn't break anything else internally. What servo would be an "upgrade" if there is such a thing for 2wd buggy?im very happy to hear this servo is distributed by hobby authority. Had very good experience with customer service in another product. In any event what would be an upgrade for the PM 3401 for 2wd buggy? Thx!!
