Dig/Shift servo horn for non-Spektrum servo

[Curt]

Hi folks, sorry if this has been covered before i had a search and didn't find any info.

Looking to replace the stock dig and shift servo on the capra/scx10.3 with a non spektrum servo so need a horn and saver setup to suit.

Anyone know of a aftermarket horn/saver that is available for 25 spline servos? I know Treal produce one, but it is difficult to get here and seems a tad pricey for all it is.

Thanks

Look up this part number by Axial: AXIC3009
These trees have the spline adapters for mini servos like the Eco Power 640. It also has the upper section of the servo saver for M3 flat head.

Unfortunately it’s from China, but I think this may work? I’m not sure on the servo spline but might be worth to upgrade to something that uses this spline. I don’t use savers personally but hope this helps

Those have the spline adapters for regular servos.

None of the adapters fit mini servos. I bought 2 sets to find that out.

It depends on the spline size. Some mini servos use the standard spline size. The ECO Powers that I picked up for my build use the standard servo size splines. Servos like the Reefs 99 use the micro spline splines instead.

I have seen 3D printed versions for the micro splines. Not sure I would trust those though.

These are what I use, and they work REALLY well.

Awesome!

Thanks for posting that.

I am looking at upgrading to THESE.

Savox says they have a 21 spline output. The part that comes with the Spektrum servo says it is a 20 spline adapter. Will the fun ever end?

So THIS might be a good compromise.
