STICK TENSION
Turn the screws clockwise a small amount using a small Phillips screwdriver to
tighten the stick tension and counterclockwise to loosen.
NOTICE: Always perform a stick tension test while turning the screws to ensure
stick tension is not too loose or too tight. Overtightening a screw can damage the
spring. Loosening a screw too far can cause a spring to fall out in the transmitter
and possibly damage the circuitry within.
