Product Details

Quadrant Style Throttle Controls for Dual Carburetor 912/914 Series Rotax Engines
Innovative design allows a neat, clean installation without a clunky splitter box


These controls feature the same high quality construction and smooth operation as our popular MCT100D panel mount controls, but they are designed for use with a quadrant.


  • Quality stainless steel construction
  • High temperature Teflon lined conduit for smooth, consistent control 
    (Cheapy controls with poly liners will not tolerate engine temperatures)
  • Available in 4, 6, 8, 12 foot and custom lengths
    • May be trimmed to length
  • Convenient dual conduit clamp for simple mounting
  • Versatile threaded conduit terminals for easy adjustment (M6x1-6g x 1 inch thread)
  • Adjustable cable stops to limit travel
  • Viton boot to dampen vibration and seal out dust on the quadrant end
  • Manufactured to the same quality standards as McFarlane's FAA-PMA controls


Includes throttle hardware kit P/N 6408 with lightweight throttle return springs P/N 7140 to prevent throttle creep.



  • Slip Fit Conduit Terminals: 2 each with M6x1-6g x 1.00 inch thread
  • Conduit: 0.188 inch OD Teflon lined wound conduit
  • Inner Wire: Heavy duty 0.062 inch diameter, 1x7 stainless steel twisted wire per MIL-DTL-87161
  • Travel (stroke): 4 inch maximum
  • Design Work Loads: Pull: 25 lbs maximum (not designed for push loads)
