I am just setting up a Caliber 30 with a JR 8103 radio as well as a Futaba 401 Gyro with S9253 digital servo. For some reason I get full servo travel when I apply left rudder but only about 1/2 travel when I apply full right rudder.

The servo moves linearly as you move the rudder from neutral to around 50% right full travel. The servo does not move at all as the rudder moves from 50-100% right. If I plug the servo directly into the rudder channel, I get symmetric travel both left and right.

I'm new at this and would appreciate any help.
