Building aircraft throttle quadrants for 45 years

Welcome to Baxter Quadrants!!


Baxter Quadrants has been a family business for more than 50 years.  We are sad to annouce that Rock Smith, our 2nd generation owner of the company who inherted it from Dick Baxter passed away on September 17, 2020.  Ryan Smith, Rock's son, has inherted Baxter Quadrants making it now a 3rd generation compnay.  Ryan will be putting in the same effort and love for the company and continuing on with its traditions, care, and quality of work that has been expected since the company started back in the late 1960's.

 
 Six different body sizes
128+ different configurations

 Dick Baxter made his
 first quadrant

   Baxter Quadrants has over 128 configurations of aircraft throttle quadrants.
Our models start with the light weight and compact 1/2 size up to the Extra Large nonreversing internal model with a 3" throttle throw.
Large nonreversing internal with a 2.5" throw, standard size nonreversing  has a 1.7" throw. Large reversing internal has a 3+" throw.
They start with a single control up to three functions with a friction control and a T-bar throttle handle.
Twin engine quadrants start with a single function to the new three function six arm quadrant.

  Our quality quadrants have been in use for over 45 years in a wide variety of experimental and ultralight aircraft.
All quadrants are made using aircraft-grade 6061-T6 or 2024-T3 aluminum and AN standard hardware.
All sizes and models may be used in side mount, center mount, or dual-control hookup.
