Servo spline chart

[marcosbong]

Hello.
Anybody can tell me where to find an UPDATED compatibility chart of the different servo splines? Because I found someones, but they don't include the newest makers like BK, KST and others.
Thanks in advance
Marcos

A chart would be great. For a quick answer, the standard size BK servos use 6mm 25T splines. Those are the same splines used by Futaba, Savox, Align, MKS (except for X8 series), Xpert, ProTek, and others. I don't know about KST.

If nobody gets an updated one, I'll make it.
When I post it, I'd like sugestions, corrections and aditions.
Thanks

It would also be a good idea to also include mini and micro size servos.

I believe that older Hitec standard size servos used 24T splines, but it is my understanding that newer Hitec servos use 25T splines.

If you want me to correct something, just tell me what to do, because I'm just copying and pasting from google.
I only have BK, Mks mini, Futaba standard, Graupner mini, Hitec micro, Hitec standard, Kst micro and TowerPro micro to check the info I get.
Thanks man

Hi,
I know this thread is quite old, but I am now looking for servo arm for my Xpert Servo CI-2401 (micro servo)
If Align and xpert share the same 25T, then why I can't put align DS450 into Xpert CI-2401??
Thank you
