Vernier-AssistTM Throttle Controls for Dual Carburetor 912/914 Series Rotax Engines
Innovative design allows a neat, clean installation without a clunky splitter box
McFarlane invents a new type of vernier engine control
This 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 counterclockwise. For extreme conduit routing or heavy carburetor load installation, slight inward or outward assist pressure could be required during rotation.
Specifications:
MCTV Throttle Series: The new Vernier-Assist throttle control is adjustable for friction and vernier engagement and is available with three different end configurations. Requires a 3/4" panel hole. Available in a variety of standard lengths or can be custom fabricated to your unique requirements.
Installation Instructions: Standard Throttle and Dual Throttle Styles

These controls are not for use on certified aircraft, or for flight controls or flight control trim tabs.
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.
