Potential Alternate:

FAA-PMA Approved Buttonless Vernier-Assist now available for your throttle!

Not only do we offer Vernier-Assist for non-certified aircraft and an extended line of FAA-PMA approved controls, the breakthrough design is now approved on throttle controls for Cessna, Piper, Beechcraft, Grumman, and Bellanca. You asked for it and now we have it!

Fine adjustments are made by rotating the knob clockwise or counterclockwise and coarse adjustments by pushing and pulling without the hassle of a release button. The McFarlane Vernier-Assist™ throttle controls use a patented roller action.

• Jam-proof safety
• Precision power adjustments
• Smooth friction control
• Light and compact
• Standard vernier action, without the button!

Part Numbering Note:

Part numbers for Vernier-Assist™ are the same as McFarlane's original push-pull FAA-PMA approved controls, except the "MC" prefix changes to "MCVA". Examples:
