High quality controls at an affordable price
Our Vernier-Assist Throttle Controls are now FAA-PMA approved!
Vernier and Friction Lock - The Best of Both
Vernier-Assist offers precision control without sacrificing safety.
McFarlane offers FAA-PMA approved throttle, propeller, mixture, cowl flap, carb heat, and cabin environment controls for many single engine Cessna, Piper, Grumman and Bellanca aircraft. We also have a wide variety of controls for use on non-certified aircraft.
Please view the Control Eligibility and Catalog Information to determine the correct part number for your specific aircraft.
Our solid metal construction and Teflon lined conduit provide precise positive control even after years of service in the harshest environments.
For more information, go to McFarlane Control Features.
McFarlane rod ends, conduit clamps, adel clamps, and wire clamps also available!
