This servo has 25 tooth on the sprocket wheel. I have bought this to replace the MPX Tiny S servo for my Funcopter V2. Everything fits except the tooth! The MPX has 24 tooth. So I hope you guys can tell me an alternative. If the total servo size is some mm larger it shouldn't matter.

What is the metal gear equivalent for this servo. using it in my sons 1/16 traxxas

In that servo line, I do not think there is a metal gear servo available. I suggesst you use the servo compare feature and see if there is something close in perhaps a different brand.

Hitec HS-82MG shoul be around the same size.

Does anyone know where i can get the servo gears for this servos ? I stripped 2 servos.
They worked ok, but i need to get new servo gears.

No to be rude, but why bother at 5 bucks each. I've had problems breaking some turnigy plastic gear servos, so I switched to been happy so far.
 Colt1873 185 points
To the best of my knowledge there are no gears available. The centering of these servos is rather ***r, so why rebuild them. The same gear strips on every servo so there is no need to save any of it for spare parts. Just toss and reorder, or move to a better servo.

To my knowledge, no gears to this servant, I had them, but changed by Turnigy metal gear is a great option

will this work in a 1/16 revo, and this may be a stupid question but can i use this more than 6 volts e.g. use a 7.4 volt pack.

As long as you go through an esc it doesn't matter what battery voltage you use. But if you don't use an esc you shouldn't go more than 6v.
 Meebert 46 points
this has the right dimensions, you don't have to worry about the voltage. All traxxas servos run on 6v if you read the specs

Not a good idea to use over 6 volts.
And should be fine in a Revo

It's a micro size servo. The real dimension without mouting foot is 28 x 13mm. It's a good replacement product with similar characteristics for Futaba S3101, Hitec HS-81 and Multiplex Tiny-S.

got 2 of these for ailerons in my 35 nitro pitts. Initially they looked very good, strong fast quiet and centered well, after about 5 flight the gears were stripped in one of them, without any ding. Dont know if I should replace it or look for something else. its a shame because it was a nice servo and I dont want to risk my plane with it.

This servo has more precise movemnets than others I bought from hobbycity, like 9320, Corona and HD.
The output gear is compatibile with Futaba horns. The only question is: Is it durable? Time will say.

These servos work great, they are a solid, had no slop and centered better than many other servos in this price range. I can't vouch for how long they will last, but so far so good. I am happy with them and will order more for some of my other projects.

This particular set went into a GP Edge 540T 50" and fit the slots perfectly without any extra cutting.

As others have mentioned they are comparable to the Hitec HS-81.

5 Stars easy.
