Van's Aircraft RV-12, Maintenance Manual

Rev. 4

OVERVIEW
The control system enables the pilot to operate the control surfaces. Forward or
aft movements of the control stick control the pitch. The pitch control linkage is a pair of
cables, each routed around a pulley. An electronic switch wired to the pitch-trim servo,
controls the pitch-trim. Side-to-side movements of the control stick controls roll via push
rods, a bell crank, and torque tubes. Rudder pedals control yaw via cables to the
rudder.
Refer to the KAI to identify the individual parts and part #’s of the control system.
• NOTE: This maintenance manual is intended to be used in conjunction with the
RV-12 Kit Assembly Instructions (KAI) when completing maintenance or repair
processes.
