Title: need t-shaped servo horn for FUTS3156 servo
Post by: Admin on December 05, 2012, 04:16:28 PM
I can't seem to find anyone selling this small futaba servo horn for the S3156 . . . I really need a t-shape.

I have servo horns for the micro servo S3114, but it's too small for the S3156.

Anyone know where to find one?

My only other affordable option is to get this at amazon (http://www.amazon.com/gp/product/B001UL11S8/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B001UL11S8&linkCode=as2&tag=societyofrobo-20). It will cause me problems, but I may just have to suck it up . . .

This ebay shop has 4 or 5 different futaba + shaped servo horns: http://stores.ebay.com/Greenfield-Hobbies/ (http://stores.ebay.com/Greenfield-Hobbies/)

I don't know the specifics of hobby servo horns, so I'm not sure if any of them are the right one.. ;)

no love . . .

I'm emailing Futaba, but it feels odd asking for a 10 cent component lol . . .

http://www.integy.com/ (http://www.integy.com/) has lots of horns. It's the only place I found full circle aluminum horns for a 23T (JR, Airtronics) spline!

Curious: why doesn't a full circle horn work?

It will work, if it's less than 0.804" in diameter.

The outer diameter of the servo output shaft is 4.96mm, 0.195".
