carbon arms?

[JBuck]

Does anybody know if these will fit the DS821 servos?

I just got my carbon arms from ReadyHeli today!! I ordered the non-offset ones because I have the CNC arms, so the elevator lever is not offset. I set the other two arms so the balls line up with the screw in the middle (as described in Finless's build video). I used the small wheel that came with the servos, and one of the holes closest to the inside of the wheel I used for the slotted hole. I had to drill my own hole for the other side through the arm and the wheel. The arms come with two holes predrilled for Futaba I assume, but on the DS821 the existing holes are too close to the shoulder on the back of the wheel so you can not put on the nut. I marked the wheel with a fine point sharpie marker around the outside of the wheel and used a sanding drum in my trusty dremal to remove the excess material.I used end nippers to remove the sides like shown in the directions included with the arms and they look just great. Make sure you install the servo and follow Finnless's build video to get it set so you don't have to use subtrim prior to selecting the first hole for the slot. Wow, took a lot of words to describe something so easy!!
Blessings,

If you have DS821's there is stock JR servo wheel that is a perfect fit. IMO this must be what the helicopter geometry was designed for. It has holes that fit both the straight and offset positions:
