Recently bought a Extra 300 and curious about EXPO Rates. The manual suggest:
40% on Low Rate for Ailerons, Elevator, and Rudder
55% on High Rate for Ailerons
70% on High Rate for Elevator
45% on High Rate for Rudder
Low Rate = 70% Travel
High Rate = 100% Travel
Push Rods in Outermost on Servo Arms, and Innermost of the Control Horns for maximum control throw distance.
Does this sound right, and what are your preferences?
