    I have an idea in my head, but not seeing behind the panel of a KitFox, I don't know if it would work. My thought has the three throttle's connected to some solid linkage, a pivoting bar perhaps, bearings on the ends attached to the frame. Each throttle is connected to a lobe coming off this pivoting bar. They all move in unison 100%. Then another lobe coming off the bar is the connection point for the throttle cable(s). I'm quite sure it could be made failure proof.

    However, as others have pointed out, once you have the muscle memory to fly from either seat, this all become irrelevant.

    Avidflyer told my story almost exactly. Except I owned a CGS Hawk for 15 years. Transitioning from center seating, left hand slide type throttle and right hand flying to left seat, right hand Vernier throttle and control stick in left hand felt strange at first but it only took a few minutes to get comfortable with the different arrangement. It's no big deal. My advise is to learn to fly it as it is and you'll get comfortable with it in no time. James Thomas

    I have a Kitfox 3 that was issued it's Airworthiness Certificate in 1991. It has an early Rotax 912. The initial setup for the throttle was a rod that was hinged on the left and right side between the instrument panel and the firewall. It had cables running from it to each carb, and one central cable to the instrument panel with a vanier control knob. Prior to my custodianship, this arrangement was removed and a split cable with a single knob from the instrument panel to both carbs was installed. In the other setup, I imagine getting the carbs to sync was a problem.

    Just a little back story.

    My first Kitfox, a model 3, had one of the earliest Rotax 912 engines.

    While it did not have a dual throttle handle, it did have a pivot bar behind the panel that had two thin throttle cables coming off each end of the bar going through the firewall to operate each individual carburetor. It worked but required
    more upkeep, more carb syncing and of course it had more failure points. I soon removed it for a much simpler safer heavier duty split throttle cable that gave me a direct connection to the carbs as used on the later model fours. Much better and simpler system.
