Having a extra servo on hand isent a bad idea and a servo tester is a nice tool to have around if for nothing else you can find center and install your servo horn with out hooking it up to your esc Also i have had servos that were bad out of the box i had 1 burned out my esc so i test all my servos before hooking them up to my escs |

I really didn't care for the stock servo in the tf2. I replaced it with a $15 Amazon 20kg ds3218 mg which was better but still meh. Running a 3bros direct power in that rig now... very happy with it. Never got the stock servo wet but it just wasn't strong or smooth enough for my taste.

Ya ive had wet servos act like that but it usualy went away pretty quick once it dryed out Sounds like your gona need a upgrade what ever the issue is rtr servos are usualy only good for a few runs some last for ever but most of the time there short lived Last edited by ferp420; 06-23-2023 at 10:23 AM. |

I have had two name brand servos act like this ... (savox & nsdrc) the servo has to be centered mechanically and in the program or it will lose its center position and could lead to continuous rotation to either side sorta like a winch servo. Both companies took care of them under warranty and came back to work as they should. Not sure if this is the case ... as mentioned could be something related to tx/rx interference or giro in the receiver... some giro ready rx can be deactivated.
