I did check this place but they are too long,I’m going to use them for aviation design servo plates and they made for short arms with regular gold clevis.

We have these available in the UK from Logic RC - they are tapped for M2, but you can easily open this out to suit the size you require ......

Man 1 to 1/2 in quality metal Futaba servos arms are sooo hard to find here. Everyone has long 3D style but most jets only need small amounts of throw and while people just cut endpoints this is the worst thing you can do to a servo. I always try to get as close to the center as possible.

Keith, Thats where using S-Bus servo's works well as you can define the centre and range to suit each individual servo for their application, but still retain full resolution from the stick input.

Hmmm but cutting throw down in the servo is the same as the radio is it not? Plus the wear pattern on the gears isn’t linear, I love me some Sbus for sure!

The best way to do it correctly and this works for all the systems ,do the mechanical way first and the radio abilities second,+I’m not able to fit longer arms to the aviation design diamond servo plate than like 1” so this is what I’m looking for.

This arms will not work the 2mm threaded holes are too big for the 1/16 clevis I have them but they don’t work with the application I’m going to use thanks for suggestions.

I've bought those SWB arms and just drilled an undersized hole whatever distance from the shaft center I needed for whatever clevis I was using and then just cut the excess end of the arm and smooth it out to shape on a bench grinder. Takes ten minutes. Or you can save some money and use this type and do the same thing.

Just be aware that some of the ebay ones are thicker so depending on your project you may not want to open up the slot on a servo cover if you're going for a more scale look and more importantly they may be too thick for a clevis and will require a threaded screw with a ball link.
