ignition interference on ailevator function during range check?
Dear Futaba,
I have a new 9C synthesized with a new 319 receiver in a gas plane using dual elevator servos. (Brison 2.4 with CH ignition) Everything works fine except for the Ailevator function during the range check. With the transmitter antenna collapsed and the engine running, the elevators do not work together consistently even at short range (20 feet). Intermittently, the elevator half that is on Channel 8 will be very slow to respond (one second) or not respond at all to stick movement, while the port elevator half (on channel 2) seems to work fine. All other radio functions are normal on range check to over 100 feet. With engine off, the ailevator problem disappears. With the antenna extended, I can go out at least 1000 feet with the engine running and not have this problem. I feel that I’ve done a good job with all the ignition isolation, i.e., 12” separation, plastic throttle pushrod, antenna routing, etc. . I am currently flying the plane and have not had any radio problems. But I’m still concerned about this. Any ideas?

RE: ignition interference on ailevator function during range check?
Hi rbuhrman,
Have you tried a filter on the second elevator servo? This might be worth a try. If the problem persists, then other than a filter and checking your setup once more, I would suggest sending the receiver into the service center to be checked out.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
