Vernier-Assist Mixture Controls 0.061" dia solid wire end

McFarlane invents a new type of vernier engine control.
This brand new type of control has all the fine adjustment benefits of an old style push-button release vernier control, with the simplicity, responsiveness and jam-proof safety of a friction lock control.

These light weight controls use a patented roller action and do not use a positive lock thread engagement. Coarse adjustments are made by pushing the knob inwards or pulling the knob outwards. Fine adjustments are made by rotating the knob clockwise or counter clockwise. For extreme conduit routing or heavy carburetor load installation, slight inward or outward assist pressure could be required during rotation.

We currently offer these new controls for use on non-certified aircraft only. However, we plan to obtain FAA-PMA approval to offer the new Vernier-Assist mechanism as an option on many of our currently approved controls for Cessna and Piper, as well as our popular MC600 universal mixture control.

• Light weight and compact behind the dash.
• Good hand space around the knob.
• Safer - Our roller action cannot jam.

Vernier action with a 3/8" panel hole!

The new Vernier-Assist mixture control offers vernier action in a light weight, compact package. It is a drop in replacement for many existing non-vernier mixture controls because it requires a 3/8" panel hole. It also only extends about 3.5 inches behind the dash making it ideal for aircraft with tight space constraints. Available in 4, 6 & 10 foot lengths.
