Default Airtronics 94357 Servo

Hello everyone,

I just recently got an Airtronics 94357 servo and find it very difficult to turn it when the car is off. Is it supposed to be like this? My buddy has a JR DS8417 servo and it moves quite easily. Any help would be appreciated. I want to be sure I don't need to get the servo repaired. It works alright when it is on. Thanks a lot.

I do not own the servo, but from a logical point of view, it should be that way.

Isn't that servo the 200 oz of torque one? If so, the motor inside must undergo severe gear reduction, so that when you turn it, the motor inside turns many many times.

Yes that servo is very hard to turn when there is no more power to it. That is a very good and durable servo.

All the 94357 servos I have seen were very difficult to move when off. So don't be concerned about it.

It isn't really "hard" to turn, it is just stiffer than what my other servos have been. I am assuming that it is just a better motor with stronger magnets and that is why.

From my experience; Digital servos tend to be easy to turn when it's not being powered while analog servos are TIGHT.

I run the 94357 in most of my cars. I have an old one that is easy to turn but all the newer ones are hard to turn while the radio is off. Don't be alarmed, this is normal. Have fun with it...it's my personal favorite servo.
