UCD3D AND 8411'S
I set mine up with a JR 8103, 549 receiver (FM), 8411 servo's (mostly).
I was getting a lot of surface buzz and chatter, even glitching, altho the plane was flyable.
At JR's suggestion, I switched to a 649 receiver (PCM) and now everything's quiet and smooth. Even the gyro's work better.
Apparently the 549 receiver is not recommended with multiple digital servos. Beware.
