The servos that we use for rudders are Hi Tec HS-82MG. The demo plane flew with a Hi Tec servo that from what i hear has been discontinued. The Hi Tec HS-82MG i guess is what replaced it. The old servo came with optional side mounts which are needed but when I recieved the Hi Tec HS-82MG it did not include these side mounts. John had to send me these mounts separately. I am sure Hi Tec still makes these mounts because i have seen them in different packages. I will have to check in on that.

i do allot of building for others and just happened to use some HS-82 and HS-85 servos the other week, both included the mounts (which i didn't use) and they list them by part #56306, you should be able to get them with that #.
