Overview

Vernier-Assist™ Throttle Controls for Dual Carburetor 912/914 Series Rotax Engines

Dual Throttle Control with 1/16" dia 1x7 twisted stainless steel wire ends.

Innovative design allows a neat, clean installation without a clunky splitter box

This 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.
  • Light weight and compact behind the panel
  • Safer - No vernier threads to jam!
  • US Patent No. 8,485,057
These light weight controls use a patent pending drive mechanism. The roller action vernier provides smooth, jam-proof coarse and fine adjustment without a release button. 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.

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

Amazing product, I am very happy by the excellent quality of this throttle control. One down side, some control stop have very small hardware, it would be nice to get a couple of those spare screws in the kit.
