Vintage futaba servo horn

[graemevw 823]

I want to keep the old futaba servos in my car, fp-s18, even though one is slow.

The problem is, the servo horns are bad. One is cracked, one has snapped.

These servos have a square drive.

Ive had a look, but cant find any. Are they even available? Do they have a particular name or anything that may help me search? Any part numbers or anything?

Would be a shame to not be able to use them. 

Thanks.

What do the look like as I remember some square drive servo savers are in my box of parts I think I have still got them.

The car uses cut down horns rather than servo savers.

Sorry I have had a look and don't have any of those I couldn't even find the ones I thought I had, I haven't come across those ones before but that doesn't mean that there is no hope to get some I wonder if they could be reproduced using 3D printing.

Ill look into making a pair, but if anyone has any, the servo post is about 4.4mm, not the 4mm acoms.
