Default Servo arm cross reference

Does anyone know if there is a cross reference for servo arms/wheels? Like what different make arms fit Futaba, Airtronics, JR, etc?

In general different brands of servo arms wont fit other makes, they may seem to go on but the fit wont be quite right and they may slip under load.

There are a few makes that are basically the same servo sold under diffrent brand names that are interchangable but I have no direct experience.

MULTIPLEX & JR ARE THE SAME
HITEC AND HOBICCO ARE THE SAME
FUTABA AND GWS ARE THE SAME

These are the only ones I know of.

Thanks for the info all. Wonder if anyone else has any idea what fits what? I have some old and new JR servos with different size output shafts. Also, I have a couple of Megatech servos where no other arms seem to fit.

It would be great if manufacturers offered conversion charts like they do for prop shaft sizes

I think Hobicco are more like the futaba since the servos are relabeled as hobicco.

I have one FMA servo that uses the same spline of Futaba.
