Basic Servo Motion

Stick/Servo Relationship

rudder   L = CCW, R = CW 
aileron  L = CCW, R = CW 
elevator F = CCW, B = CW

Non-Reversing Installation

Plausible Rudder/Elevator Combinations

DRR/DLB (inverted, for ezflyer)
LTL/RTT (flat, on top, 300s)
RTT/RBB (2 rights, above and below wing)
LTL/RBB (stacked, flat, around wing)
LTL/LBT (left, high, up and down)

Best configuration for RET (rudder/elevator/throttle) flyer (e.g. Blu-Baby) with push rods on outside of plane
