Kraton Servo upgrade?

[bradley fletch]

I need to upgrade my servo as the stock one has just have up. I was looking to get a jx ecoboost 36kg and im not sure if there is anything else i will need to make this work or will it fit straight out of the box. Also what do i do with the servo saver as i have heard they are to loose and you cant get maximum advantage without upgrading it?

You will need a 25t servo horn as they have a propriety 26t (iirc) horn. Other than that you are good to go.

If you have an older Arrma, the saver is adjustable. On the later models it isn't, however you can adjust it with a circlip:

The jx ecoboost servos have the torque required for the kraton but the gears are aluminum and they stripped out pretty fast for me. I went with a promodler servo and haven't looked back.

23t.

I used the Arrma 25t Servo horn on my notorious vs the Servo horn that came with the aftermarket Servo. It raises the horn up a bit higher than aftermarket to make the geometry connecting it with the steering linkage much better. Arrma part no ARA34006.
