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.
I don't like the idea of inserts, either. It's just one more place for some movement and/or wear.
It's a good point about the JR stuff being tight - the Airtronics horns are really snug on the airtronics servos, but the JR horns slip right on the Airtronics servos.
So, I just tried an Airtronics horn on a JR servo and it wouldn't go - seems to me that they may have the same spline pattern, but JR has a slightly larger diameter (gear?) than Airtronics. That should be enough for me to not use JR stuff on Airtronics...
