Recommended replacement servo horns for JR servos
I had what was seemingly a mild crash at first today, but when I inspected the damage, I found that one of my servo horns snapped (I had previously rebuilt the servo with metal gears, or else the servo gears probably would have stripped). I have DS285 servos and was using the servo arms that came in the package. However, I cannot find the same horns for sale anywhere, so it looks like I may have to replace all of them.
What are the thoughts on nylon vs. fiber-reinforced plastic vs. CNC for servo arms? What's a good replacement arm?

Not CNC, as you WILL replace gears.
I use stock Hitec arms on my Trex, but DuBro arms on my EP8 and Hurricane.

I went to one of the RC car places close by and they had the Dubro arms for a S241 servo, which is the analog cousin to the DS285. They looked awfully flimsy. Are they stronger than they look?

Can anybody comment on the strength of the Dubro servo arms?
