I have a Hanger 9 AT-6. It flys with individual airleron servos. I am having a heck of a time getting rid of servo jitter. I have switched receivers, transmitters, batteries, and servos with no success. I tried installing an FMA noise trap, and a home built noise trap (based on the 74hco4 hex inverter) which helped but not enough. This evening I clearly established that the noise is coming from the airleron setup. When I disconnected the airleron wiring at the splitter the problem went away. When I attached any two servos and then moved them apart the jitters came back. Move them together again, jitters gone. Tested this several times. I had a similar problem with my Top Flight corsair and the flap servos which I solved by making the leads as short as possible. This is not an option in the AT-6 as they are as short as possible already.

The airleron servos are new Futaba s3003. The replacement servos tried were GWS. The radios tried are a Futaba super 7, and the old manual Futaba seven channel. The receivers tried are a FMA interceptor and the Futaba 127 7 channel FM.

Help!!
