Joe, here's another source for the pulleys and arms that I've used in the past. They work just as well as the H9 stuff, it's just easier for me to get H9's equipment. I thought maybe they had Airtronics specific arms and such, but it appears as though they combine them with JR. I don't know if JR and Airtronics are close on their gear pattern, but I know JR arms are always very tight (to the point of needing to heat them up sometimes to get them off) on JR servos.
